For more details regarding the technical specifications of the microphones that can be combined with the XPT800 sound level meter, please consult the relevant manuals or contact the Manufacturer.
4.6.2 Preamplifier
The MP800 preamplifier performs the task of amplifying the weak signal provided by the microphone. The peculiar dynamic performance combined with low noise enables the detection of both very low and high level sound signals using a single measurement range. The MP800 preamplifier is also equipped with a CTC (Capacitive Transducer Calibration) calibration device, which allows the drifts of the entire measurement chain, including the microphone, to be kept under control by means of a charge-sharing scheme.
Available models are listed in chapters “5.2 Standard configuration” on page 27 and “5.3 Options and accessories” on page 29.
Heater
The MP800 preamplifier is equipped with an internal heater, which can be activated from the GUI. Use of the heater is recommended to reduce condensation on transduction chain components in outdoor uses with high humidity levels and low temperatures.
Automatic detection
A chip inside the preamplifier stores certain information about the transduction chain (e.g., the pre-amplifier serial number) that is automatically detected by the XPT800 sound level meter, allowing the user to use different transduction chains without the need for setting operations.
4.6.3 Instrument
The signal from the preamplifier reaches the input of the A/D converter. The analog signal is converted into numerical form by the A/D. The exceptional resolution of the converter, which extends over a range of more than 140 dB, allows high accuracy to be maintained over a single measurement range of about 125 dB where digitization error is negligible. In the DSP, levels with broadband frequency weightings (A, B, C, and Z) and levels with both octave and third-octave constant percentage bandwidth weightings are calculated in parallel. Peak levels are also calculated. The levels calculated by the DSP are transmitted to the microprocessor for further processing, display, storage.
The microprocessor supervises all instrument processes: management of the electrical calibrator, memory, TFT touch display, keyboard, network and communication devices (LAN, Wi-Fi, 4G), GPS, codec, and interfaces (RS232C and USB).

4.6.4 Outdoor microphone unit (optional)
Info
For more information, see the outdoor microphone unit manual provided with the unit.
The WSO microphone unit is suitable for prolonged time surveys in outdoor environments, including unattended fixed locations. The unit is adequately protected from rain and wind, and the heated pre-amplifier provides stability of acoustic parameters over time and allows surveys in a wide range of environmental conditions.
The preamplifier of Senseca sound level meters, coupled with the outdoor microphone unit, is equipped with a circuit for electrical calibration of the preamplifier-microphone capsule chain, which uses a charge-sharing technique.
The unit free-field frequency response meets class 1 specifications according to IEC 61672 (and IEC60651).
The WSO microphone unit must always be placed vertically to allow the rain shield to perform its function and can be used to detect both airborne and ground-borne noise. Senseca sound level meters make spectral corrections to measurements to ensure class 1 tolerances according to IEC61672 in every situation.
The easy disassembly and reassembly of the unit allows periodic verification of electroacoustic characteristics to be carried out in the same way as with a standard measuring microphone, using a standard 12 " microphone calibrator.

8 Viewing modes
Info
Display modes are available by accessing the MEASURE menu from the ICON MENU.
XPT800 calculates all broadband acoustic parameters in parallel with all available weighting filters. It allows parameter calculations with linear, exponential and moving averages. It also allows real-time and parallel calculations of broadband parameters with spectra in octave or third-octave bands. Functions for statistical analysis allow 7 percentile levels of broadband parameters and frequency spectra to be calculated in octave or third-octave bands; in addition, level distribution and cumulative functions are calculated.
The set of acoustic parameters selectable for display in the various graphical screens is completely independent of the set of parameters or groups of parameters selected for storage and datalogging. The parameters available for display are the full set while the parameters subject to storage are user-selectable through specific panels (see datalogging setup section).

9 Getting started: Main Functions
The most frequently used functions are described below; for a complete discussion of the instrument operation and settings, see the section “10 Advanced functions” on page 66.
9.1 Calibration
Sound level meter calibration (adjustment) should be carried out periodically, normally before and after each measurement session, in order to ensure the validity of the measurements made by the sound level meter, as the sensitivity of the microphone and the response of the electronic circuits may vary slightly over time or may be affected by environmental conditions such as temperature, atmospheric pressure and humidity.
Acoustic calibration also includes internal electrical calibration. Electrical calibration enables the alignment of electrical parameters in the measurement chain
Info
- More information on calibration settings can be found in the chapter "10.1 Setting the calibration parameters" on page 66".
- Before starting the calibration procedure, carefully read the calibrator manual provided with the calibrator.
Notice!
- It is recommended to use the model HD2020 calibrator, supplied upon request
- Another class 1 calibrator conforming to IEC60942 and with 1/2" cavity can be used, after verifying compatibility and technical specifications.
- When using class 1 calibrators alternative to the HD2020 model, the nominal emission level stated in the calibration certificate must be verified, and the "Cal_Level" parameter in use in the menu related to the calibration setup must be adjusted. If stated by the manufacturer, corrections per load volume should be considered.
Before performing an acoustic calibration:
- make sure that the environment in which you are operating is suitable: no sudden noise, no vibration are present on the supporting surface, thermal stability of the instrument;
- make sure that the microphone and especially the microphone diaphragm are clean; in case a check of the condition of the microphone capsule is to be performed, refer to “14.2 Microphone cleaning (microphone diaphragm)” on page 94;
- in case of accessories installed on the instrument, such as a windshield if any, or if you want to customize the calibration settings, refer to section "10.1.1 Setup" on page 66;
- make sure that there is no measurement in progress; if it is, it must be stopped before starting calibration.
To perform a calibration:
1 Turn off the sound calibrator.
2 Carefully insert the microphone all the way into the cavity of the calibrator.
3 Turn on the XPT800 sound level meter.
4 Follow any specific recommendations in the calibrator manual in this regard.
| 5 In the ICON MENU, press the SYS-FUNC icon to access the system app menus.6 Access the CALIBRATION, PROCEDURE pages in succession.7 Set in the "Expected" field, if not yet set in the calibration setup (CALIBRATION > SETUP > Level), the nominal value stated by the manufacturer or taken from calibration certificate, of calibrator output (e.g., 94.00) at 1KHz frequency.8 Press "Play" to start the reading.9 If the level is enough stable, press "CAL" to start the adjustment procedure.10 The "CAL" button remains inactive until the calibration procedure is finished, so calibration corrections are not allowed. |  |
11 When done, turn off the sound calibrator, slide the microphone out of the cavity.
When the calibration is completed, the date, time and correction are updated. Access to the Calibration history panel is allowed only after the calibration is completed.
9.2 Setting the duration of a measurement
Notice!
If the measurement duration is not set, the measurement will not be interrupted unless manually or when the memory or battery runs out.

Info
It is also possible to:
- perform subtraction between two parameters, see chapter "9.5 Subtraction of two acoustic parameters" on page 58.
- set alarms and exceedances, see chapter "9.7 Set alarms on exceedances" on page 60.
9.4 Set acoustic parameters to be stored
The XPT800 sound level meter allows parallel storage of a very large set of acoustic parameters with sampling down to 10ms. Through the Time History, Report, Events, Globals storage groups, the user has logging tools that allow recording of sound phenomena both with high temporal resolution and with integrated sampling over medium or long times thus being able to quantify sound emissions on an hourly or daily basis, for example, or with hourly moving average integrations. In addition, storage of time histories and calculated acoustic parameter values of occasional events is also possible independently of continuous storage of levels, saving the user, if necessary, from storing data not of interest. The Time History, Report, Events, and Globals storage groups can be used simultaneously, providing the acoustician with a versatile logging tool that can be adapted to any need.
Info
All modified settings remain stored in the "current" and reloaded at power-up. The current setup, if modified, will be followed by an asterisk to indicate to the user that an unsaved change has occurred. If the user wishes, he/she can store the complete set of settings in a setup file by accessing APPLICATION MANAGER which is the application from which to manage the storage of the customized settings, see chapter "10.4 Custom measurement setups" on page 71.

10 Advanced functions
10.1 Setting the calibration parameters
The XPT800 sound level meter, with the standard transduction chain consisting of the MP800 preamplifier and model MP800 class 1 free-field microphone, is adjusted at the factory and delivered calibrated. Adjustment with a class 1 sound calibrator should be carried out periodically, normally before and after each measurement session, to ensure the validity of the measurements made by the sound level meter, as the sensitivity of the microphone and the response of the electronic circuits may vary slightly over time or may be affected by environmental conditions such as temperature, atmospheric pressure and humidity. In addition, XPT800 has an internal compensation function for environmental conditions corrections.
10.1.1 Setup
The instrument allows settings of the following parameters:
• Acoustic Field corrections;
• Windscreen and Outdoor microphone protection corrections (Shield correction);
- Emission level of sound calibrator used (Level);
- Calibration mode, manual or automatic.
To setup the calibration parameters of the instrument:
| 1 In the ICON MENU, press the SYS-FUNC icon to access the system and measure configuration menus.2 Access the CALIBRATION and SETUP pages in succession.3 Set the desired parameters. | SYSTEM APPS<SETUPELECTRIC cal. corr. 0.00dBElectric cal. level 91.0dB :Calibration mode MAN :El. calibration OFF :Electric cal. timer: 1h :Microphone input MIC :Environmental corr. ON :Shield correction WS90 : |
Acoustic field
With the supplied MC800 microphone, which has a frequency response optimized for "Free Field" (FF), if the parameter is set to "Free Field" (FF), correction is applied accordingly. Correction by random incidence can be enabled by setting the parameter to "Random Incidence" (RI). This setting is necessary for surveying in accordance with ANSI standards. For example, in case you choose a microphone with frequency response optimized for "diffuse field," the normal setting is "Random Incidence" (RI). You can enable correction for making free-field measurements by setting the parameter to "Free Field" (FF). This setting is necessary for measurements in accordance with IEC standards.
Correction applied for the use of WS90 or WSO windscreens (Shield correction)
Allows the sound level meter's frequency response to be corrected when either the windscreen WS90, supplied with the sound level meter, or the outdoor protection kit WSO is used. When this parameter is set to WS90, WSO the sound level meter's frequency response is corrected for the pres-
ence of the windscreen or outdoor protection respectively.
Calibrator emission level (Level)
This is the nominal emission value of the acoustic calibrator used for adjustment of readings; it is stated by the manufacturer or obtained from calibration certificate. The instrument must be set to the same level by setting precisely the Cal_level parameter; the possible range is 90.00 ÷ 130.00 dB.
Correction applied after calibration (Correction)
The current correction level is shown after a successful calibration procedure. The correction level expressed in dB, indicates the level difference applied by the calibration algorithm from the factory calibration.
Calibration mode
The following options are available:
- Manual (MAN);
• Automatic (AUTO).
Automatic: when Calibration Mode is set to AUTO, the instrument uses detectors to automatically detect the presence of a calibration tone in the signal coming from the microphone. When the calibration tone is detected, a pop-up prompts the user to perform calibration.
Info
For a complete description of the available parameters and options, see the section "19 Appendix B – Parameters" on page 104.
10.1.2 Calibrations History

10.3.1 Audio recording mode
By acting on the "Log_audio_mode" parameter, audio logging can be set to:
- disabled (OFF): durante la registrazione dei dati non avviene nessuna registrazione audio;
- continuous audio recording (CONT): the audio signal is stored without interruption until the end of the measurement with datalogging.
- event-driven audio recording (TRG); audio recording, during a measurement with datalogging, is activated only when the set trigger condition is reached and is deactivated when the trigger condition is no longer satisfied.
Continuous audio recording
During "continuous" audio recording, the audio signal is stored without interruption until the end of the measurement.
Event-based audio recording
During "event-driven" audio recording, the audio signal is stored only when the set trigger condition is reached and is deactivated when the trigger condition is no longer met. It is possible, during the same measurement, to record another audio if the set trigger condition is met again.
To enable event-based audio recording, it is also necessary to set and activate the exceedances on the desired parameter as well, as described in the chapter “9.7 Set alarms on exceedances” on page 60.

11 Managing measurement data files
Each time a measurement with logging is performed, a folder is created in the active storage device containing data files with the extension *.dodl and other file types.
The folder path is as follows:
Unit_name:\XPT800_My_serial_number\Measure\yyyyMMdd_hhmmss\
If the parameter SETTINGS > DATALOGGER> SETUP> Log_sequence = OFF, the instrument creates a folder with the start date and time of the new acquisition in the name. In this way, each measurement corresponds to a new folder.
If the parameter SETTINGS > DATALOGGER > SETUP> Log_sequence = ON*, the measurements are stored in the same folder and the name of each data file is preceded by a sequential numbering such as: 0001_globals.dodl, 0002_globals.dodl for globals-type data files, or 0001_history.dodl, 0002_history.dodl for time history-type files, and so on for other types of data files such as Reports, Events, etc..
Although the XPT800 instrument has 4GB of available internal memory and a SD memory slot (TBA), other storage options are available:
• USB-C: external storage device
- Cloud: manual or automatic upload of data to NS-Storage web service
11.1 Setting the data file storage unit
The instrument allows you to use the internal eMMC memory or alternatively an external USB-C drive.
Selection of memory to be used is automatic:
- if NO external drive is inserted, the storage location is automatically set to the internal eMMC memory

Connect the XPT800 instrument to a PC (Windows and Mac) using a USB-C cable connected to USB connector. The instrument will now be visible as a memory unit.
It's possible to:
• View system files (System)
• display and copy measurement data files (Measure)
• view configurations (Setup)
• view playback files (Traces)
13 Firmware update and options
The firmware, i.e. the program that manages all the instrument's functions, can be updated by transferring the file from a PC to the XPT800 via the USB-C ports. This allows the functionality of the instrument to be updated.
To proceed with the update, use the FW UPGRADE function accessible from the SYS-FUNC icon.
Warning!
During the procedure the power supply status must be sufficient to perform the update.
- With external power supply, DO NOT remove the power cable until the firmware update is complete.
- With battery power, the battery must be close to 100% to ensure that the boot-loader functions are not interrupted and thus avoid possible FLASH memory write errors.
Info
The BL (boot-loader) accepts that there are also other files in the 'firmware' directory. The files will be evaluated starting with the extension ".hex", then whether the attribute "archive" is set, and finally the contents of the APP table "infoAPP" contained in the file. If there is more than one file in the directory that meets these requirements, the first one proposed by the file manager will be used for update.

14 Maintenance Operations
14.1 Cleaning the Instrument
Clean the device with a soft, clean cloth or, when necessary, slightly moistened with clean water.
Warning!
Take care that no moisture enters the enclosure.
Forbidden!
Do not use sprays, solvents, alcohol-based cleaners or abrasives.
14.2 Microphone cleaning (microphone diaphragm)
To avoid permanent alterations in frequency response and consequent degradation of performance that may invalidate the instrument's compliance with class 1 tolerance limits, the accumulation of dust and dirt particles on the microphone diaphragm must be avoided.
The microphone capsule and diaphragm must be periodically inspected and, if necessary and possible, cleaned. Inspection and cleaning, if necessary, are normally carried out during periodic calibration at the accredited Senseca Italy Srl laboratory.
14.3 Accredited periodical calibration
This must be performed at Senseca Italy's UNI CEI EN ISO/IEC 17025 accredited laboratories or at another accredited laboratory for the calibration of sound level meters and octave or third octave filters.
Periodic calibration must be carried out in accordance with international technical standards.
Notice!
It is recommended to calibrate the unit annually.
15 Troubleshooting Guide
15.1 Formatting eMMC memory (FORMAT)
Warning!
Before formatting, all folders in the eMMC memory must be backed up.
Formatting the eMMC memory results in the deletion of the following contents:
- microphone serial number
- system configuration
- access points configurations
• measurement setups in APPLICATION MANAGER - stored measurement data
- generator files
- audio tracks
- calibration history
- any firmware files (*.hex) loaded in the relevant folder
Two equivalent formatting modes are possible:
- formatting from device
- formatting from PC
Formatting from device
| 1 In the ICON MENU, press the SYS-FUNC icon to access the system configuration and measurement menus.2 Access the INITIALISATION and PROCEDURES pages in succession.3 Press on FORMAT. To confirm the operation, press OK, to cancel press CANCEL. |  |
Formatting from pc
The eMMC memory is recognised by the PC as an external drive with the XPT800 model name. The format command available on Windows determines the formatting of data and settings as described in the warning at the beginning of the paragraph. On the next reboot, the sound level meter's operating system restores the device's default settings (please note that the microphone serial number must be restored. See XPT80X_SLM_Config).
Formatting details:
- Format: exFAT
• Size of allocation unit: 32kilobyte - Label: XPT800
15.2 Restoring Parameters to Default Settings (Reset)
Resetting the settings resets the setup parameters to the default settings.
Warning!
The Reset procedure, if a formatting has been performed, does not restore all previous conditions.
The reset procedure does not delete:
- Measurement data files (unit:\XPT800_xxxxxxxxxx\Measure)
- Measurement settings (unit:\XPT800_xxxxxxxxx\Setup)
- Calibration history
To perform a reset, follow this procedure:
1 Ensure that no measuring and recording is in progress.
2 Make sure you have saved any configurations being edited in APPLICATION MANAGER.
| 3 In the ICON MENU, press the SYS-FUNC icon to access the system configuration menus.4 Access the INITIALISATION and PROCEDURE pages.5 Touch on INIT SETUP. To confirm the operation, press OK, to cancel press CANCEL. |  |
15.3 Malfunctions, causes and possible solutions
◆ Calibration procedure fails:
The calibration correction is applied and written in the Curr.Att. field, along with the date and time, only if it is within the expected range. If the calibration procedure fails, the correction is not applied and written.
Failure to apply the correction may be due to the following factors:
- microphone out of nominal specification
• sound calibrator out of nominal specification
• acoustic calibrator off or with incorrect level setting - expected calibration value (expected field) not set correctly with respect to the calibrator used.
Possible solutions:
- Ensure that the instrument is not exposed to high noise and/or vibration and that the acoustic calibrator and sound level meter are firmly aligned, and the microphone is fully inserted into the calibrator cavity.
- Check that the rubber sealing ring inside the calibrator cavity is not damaged and is correctly positioned.
- Repeat after waiting for the end of the stabilization time.
❖ The sound levels measured by the sound level meter appear to be incorrect:
- Check that the preamplifier is fully inserted into the connector on the sound level meter (the push-pull connector "clicks" when correctly inserted).
- Ensure that the microphone capsule is correctly screwed onto the microphone preamplifier.
- Verify that there is no dirt on the microphone protection grid.
- When using a microphone extension cable, try connecting the preamplifier directly to the sound level meter, excluding the cable as a possible cause of malfunctioning.
- Check that the displayed acoustic parameter is correct (we recommend using an instantaneous parameter such as LAFp)
- Check that the microphone protection grid is screwed tightly onto the capsule.
- Ensure that there is no condensation on the microphone capsule or preamplifier. Avoid switching on the sound level meter in conditions where condensation may occur. For measurements in high humidity or rain, use the WSO outdoor microphone protection unit.
- Activate the preamplifier heater.
❖ The sound level meter switches off immediately after the power-up presentation screen:
- Battery is depleted and must be charged, use external power supply as an alternative.
❖ The sound level meter does not communicate with the PC:
- Check that the connection cable is correctly plugged into the USB-C connector on the sound level meter and that it is connected to a USB socket on the PC.
- If the USB interface is used, check that, on the sound level meter, are not activated functions for which the USB port is to be disabled (e.g. Log_Sync or measurement with storage).
✿ Continuous logging cannot be activated. The instrument starts measurements without data recording:
- Out of memory. Download data and/or delete memory.
❖ Manual audio recording does not work:
- Check that the audio logging mode is on TRG (EDIT APP > LOG > AUDIO > Audio logging = TRG).
❖ Automatic audio recording does not start:
- Check that the audio logging mode is on TRG (EDIT APP > LOG > AUDIO > Audio logging = TRG).
- Verify trigger input (EDIT APP > TRIGGER > INPUT > SLM = activate check box for parameter on which trigger thresholds are set).
- Check the activation thresholds values by tapping on the parameter selected for triggers in the SLM screen.
16 Long-term storage
- Switch off the instrument as indicated in chapter "6.3 Switching off" on page 40.
- If the instrument is to be stored for more than 2 weeks, remove the battery as indicated in chapter "5.5.3 Battery insertion and replacement" on page 37.
• We recommend storing the instrument in its case and in a dry environment.
Warning!
In case the instrument is externally powered or charging, do not remove the power cord before turning off the instrument. Removing the power cable with the instrument still on, could result in the loss of unsaved data.

20 Appendix C - Trigger
The trigger function can be managed through parameters which can be set either in EDIT APP > TRIGGER or in the SETTINGS > TRIGGER menu. With this function, it is possible to automatically isolate a sound event during measurement, by identifying a change in sound level or by synchronising with an external signal or manually by pressing a button. The acoustic descriptors used by the trigger function are those selectable in the SLM view (see “9.3 Select acoustic parameters to be displayed” on page 54). The level change that triggers the event identification can be either positive or negative, and the trigger threshold can be set to a different level from the deactivation threshold. The following image shows an example of sound event capture with positive polarity. The sound level (LAeq) exceeds the set activation threshold at the time indicated by cursor V2 and then the stop threshold at the time indicated by cursor V3.

To prevent even short pulses from being identified as sound events, a minimum activation duration (duration filter) of up to a maximum of 10s can be set. If the activation threshold is exceeded for less than the set time, the event is not taken into account. A stop delay can also be set: when the deactivation threshold is reached, the event is delayed for the set time up to a maximum of 3600s. In the example above, as the trigger conditions persist beyond the set minimum duration, i.e. at least until time T1, the action provided by the trigger function begins; this includes the seconds before the trigger threshold is exceeded (pre-trigger). The pre-trigger interval can be set via the parameter Trg_pretrigger. The trigger action is terminated at time T2, with a delay equal to the stop delay starting from the instant identified by cursor V3 corresponding to the crossing of the stop threshold. The trigger to identify an event, can also be activated by means of an electrical signal connected to the Trigger I/O input (20.5 Trigger I/O Input) or by pressing a button from the interface (see 10.5 Customizing markers). In both cases the minimum duration parameter has no effect, and the event starts as soon as the trigger is detected.
20.1 Exceedances settings
One or more of the acoustic parameters set and displayed in the SLM screen can be used to trigger. The parameters selected and activated to generate the trigger will be available as input for the trigger. In the case of several activated parameters, it will be possible to combine them (OR/END logic) together to generate advanced multi-parameter triggers.
| Tap on one of the parameters on the SLM screen to access the panel relating to the parameter on which a trigger is to be activated; from there, use the three dots: to set the relevant parameters such as the exceedance thresholds that trigger on and off, the mode and duration. | P1: √ XLAFp ... Help:LXFp: sound pressure level FastX = A, C + B or Z (selectable) |
20.1.1 Exceedance of SLM parameters
Reaching the set conditions for exceedances can be used to generate a trigger. The trigger, once activated, can generate a specific action (e.g. the automatic recording of an audio signal).
| Set the exceedance activation MODE (see “20.1.2 Exceedance SLM mode (Exc_slm_mode)”)Set activation threshold value (MAX)Set deactivation threshold value (MIN)Set minimum exceedance duration time (duration filter) for trigger activation (see “20.1.4 SLM exceedance duration filter (Exc_slm_duration)”) | MODE: POSMAX: 100.0MIN: 90.0DURATION: 0 |
20.1.2 Exceedance SLM mode (Exc\_slm\_mode)
Through the MODE parameter, it is possible to trigger on SLM acoustic parameters exceedances according to 4 different modes described below. Four values are available: POS, NEG, IN, OUT
POS
The exceedance occurs (trigger ON) when the sound level goes from a lower to a higher value than the Max value (threshold Max) set as the trigger activation threshold and is deactivated (trigger OFF) when the sound level goes from a higher to a lower value than the Min value (threshold Min) set as the trigger deactivation threshold.

NEG
The exceedance occurs (trigger ON) when the sound level goes from a higher to a lower value than the Min (threshold Min) value set as the trigger activation threshold and is deactivated (trigger OFF) when the sound level goes from a lower to a higher value than the Max value (threshold Max) set as the trigger deactivation threshold.
line
| Date | Value | | ---------- | ----- | | 03/04/2024 | 110 | | 09/04/2024 | 105 |Fig. 17 - Trigger mode NEG

20.1.3 Exceedance SLM thresholds (Exc\_slm\_threshold)
User input of two level values Max and Min is required: start threshold or stop threshold depending on the selected mode (POS, NEG, IN, OUT).
Trigger start threshold: the threshold for triggering on the level reached by the selected parameter.
Trigger stop threshold: a separate deactivation threshold for triggering on the level reached by the selected parameter.
20.1.4 SLM exceedance duration filter (Exc\_slm\_duration)
A duration filter is available to eliminate false triggers. An event is only triggered if the over level condition persists for a number of seconds at least equal to this parameter (parameter value 0-10s).
20.1.5 Enabling SLM exceedances (Exc\_slm\_enable)
Enables or disables the use of exceedance on SLM (Trigger Input) parameters
| Red bell = ONGrey bell = OFF | Exceedance on/off | Settings |
20.2 Setup trigger
(EDIT APP > TRIGGER > SETUP or SETTINGS > TRIGGER > SETUP)
General trigger parameters are available for setting on SETUP menu
20.2.1 Pre-trigger
This is the time interval before the trigger occurrence. The event generated by the trigger activation will also include the configurable time interval before the trigger activation. The function makes it possible to also detect or include in the calculations the level increase phase of a sound event or particularly fast events whose phase before the trigger is triggered. (parameter value 0-10s)
20.2.2 Post-trigger duration
After the deactivation threshold is reached, the trigger remains active for a user-settable time. It is possible in this way, for example, to encode the 'tail' of a sound event (parameter value 0-3600s).
20.3 INPUT
(EDIT APP > TRIGGER > INPUT)
The trigger input can be chosen from one or more of the parameters set in the SLM screen and activated for the trigger. The parameters selectable as trigger inputs are only those for which the Exceedance on/off (bell) function has been activated in the setting panel relating to the selected SLM parameter. Parameters selected as trigger inputs can be set to each other in OR or END logic.
20.3.1 SLM
The screen shows 12 parameters (among which there can also be coupled parameters of the type L1 minus L2), 6 related to Par1 and 6 related to Par 2. Only the parameters available for the trigger (Exceedance on) will be active; those not available (Exceedance off) will be visible but deactivated and in grey colour; for the latter, the selection on/off checkbox cannot be activated.
The on/off checkbox can be used to activate or deactivate the parameter for its use as a trigger during measurement.
If the logic between Par1 and Par2 is set to AND, it is possible to select one of the activated SLM parameters in Par2 for the trigger (Exceedance on). Activating the AND logic will only trigger if both Par1 and Par2 reach the values set in the exceedance panel.
20.3.2 MRK
Allows the marker name to be changed and activated by check box.
20.3.3 MIX
Trigger IN (ON/OFF): enables external trigger on Trigger I/O input
20.4 Setting exceedances of a spectrum in octave or third octave bands
The exceedance monitoring function on the octave or third-octave band spectrum allows min and max thresholds to be set for each band (spectrum exceedance mask). The exceeding of one or more bands generates a trigger.
Setting thresholds for each frequency band:
From graphic interface in EDIT APP/TRIGGER/SPECTRUM
- Select the band using the vertical cursor
- Modify the thresholds of the Min and Max fields
- click SAVE (the file exceedances_xOCT.json is modified and stored - see below).
- Click LOAD to load and display the mask (in orange color) with the thresholds set.

20.4.1 Enabling Spectrum exceedances
From graphic interface access the spectrum view (or EDIT APP/SEL.VIEW/SPECTRUM)
- Tap the bell to access the setting
• BANDS: select SINGLE or ALL
SINGLE (reaching the conditions of at least one band generates the surplus)
ALL (reaching of exceedance conditions must be true for all bands)
- Select required MODE (see 20.1.2 Exceedance SLM mode (Exc_slm_mode) on page 113)
- Activate the exceedance switching the cursor to ON
