Safety Precautions

1 Safety Features and Precautions

You have selected an instrument which provides you with a high level of safety.

This instrument fulfills the requirements of applicable EU guidelines and national regulations. We confirm this with the CE marking. The relevant declaration of conformity can be obtained from GMC-I Messtechnik GmbH.

The TRMS digital multimeter has been manufactured and tested in accordance with the following safety regulations: IEC 61010-1:2010/DIN EN 61010-1:2011/VDE 0411-1:2011.

When used for its intended purpose (see page 10), safety of the operator, as well as that of the instrument, is assured. Their safety is however not guaranteed, if the instrument is used improperly or handled carelessly.

In order to maintain flawless technical safety conditions, and to assure safe use, it is imperative that you read the operating instructions thoroughly and carefully before placing your instrument into service, and that you follow all instructions contained therein.

The multimeter is equipped with an automatic socket blocking mechanism for your safety, and in order to safeguard your instrument. This mechanism is linked to the rotary switch and only allows access to those jacks which are actually required for the selected function. It also prevents the user from turning the rotary switch to impermissible functions after the measurement cables have already been plugged in.

Measuring Categories and their Significance per IEC 61010-1

CAT Definition
I	Measurements in electrical circuitswhich are not directly connected to the mains:for example electrical systems in motor vehicles and aircraft, batteries etc.
II	Measurements in electrical circuitswhich are electrically connected to the low-voltage mains:with plugs, e.g. at home, in the office or laboratory etc.
III	Measurements in building installations:stationary power consumers, distributor terminals, devices connected permanently to the distributor
IV	Measurements at power sources for low-voltage installations:meters, mains terminals, primary overvoltage protection devices

The measuring category and the maximum rated voltage which are printed on the device apply to your measuring instrument, for example 1000 V CAT III.

For the application of measuring cables see page 66.

Observe the following safety precautions:

- The multimeter may not be used in potentially explosive atmospheres.

- The multimeter may only be operated by persons who are capable of recognizing contact hazards and taking the appropriate safety precautions. Contact hazards according to standard exist anywhere, where voltages of greater than 33 V RMS or 70 V DC may occur. Avoid working alone when taking measurements which involve contact hazards. Be certain that a second person is present.

- Maximum allowable voltage between the voltage measuring terminals, and between all connections and earth is 1000 V for measuring category III, or 600 V for measuring category IV. Exception SECULIFE HITAM/HITMD: 600 V CAT III and 300 V CAT IV.

• Be prepared for the occurrence of unexpected voltages at devices under test (e.g. defective devices). For example, capacitors may be dangerously charged.
• Make certain that the measurement cables are in flawless condition, e.g. no damage to insulation, no interruptions in cables or plugs etc.
• No measurements may be made with this instrument in electrical circuits with corona discharge (high-voltage).
• Special care is required when measurements are made in HF electrical circuits. Dangerous pulsating voltages may be present.
• Measurements under moist ambient conditions are not permitted.
• Be absolutely certain that the measuring ranges are not overloaded beyond their allowable capacities. Limit values are included in chapter 8, "Technical Data", in the table entitled "Measuring Functions and Measuring Ranges" in the "Overload Capacity" column.
• The multimeter may only be operated with installed batteries or rechargeable batteries. Dangerous currents and voltages are otherwise not indicated, and the instrument may be damaged.
• The instrument may not be operated if the fuse cover or the battery compartment lid has been removed, or if its housing is open.
• The input for the current measuring range is equipped with a fuse link (exception: METRAHIT BASE). Maximum permissible voltage for the measuring circuit (= rated voltage of the fuse) is 1000 V AC/DC. Use specified fuses only (see page 59)! The fuse must have a breaking capacity of at least 30 kA.

Opening of Equipment / Repair

The equipment may be opened only by authorized service personnel to ensure the safe and correct operation of the equipment and to keep the warranty valid.

Even original spare parts may be installed only by authorized service personnel.

The instrument is switched off automatically if the measured value remains unchanged for a long period of time (maximum measured value fluctuation of approx. 0.8% of the measuring range per minute, or 1 °C or 1 °F per minute), and if none of the keys or the rotary switch have been activated before a selected period of time in minutes has elapsed (see "RPFF" parameter on page 49.)

Shutdown is acknowledged with a brief acoustic signal.

Exceptions include:

Transmission and memory mode operation, continuous operation and whenever a dangerous voltage is applied to the input (U > 55 V AC or U > 70 V DC).

Disabling Automatic Shutdown

The instrument can be set to continuous operation.

Simultaneously press the this end.

The “Continuous On” function is indicated at by means of the ON display to the right of the battery symbol.

The “Continuous On” setting can only be cancelled by changing the respective parameter, and not by switching the instrument off (see “RPoff” on page 49).

4 Control Functions

4.1 Selecting Measuring Functions and Measuring Ranges

The rotary switch is linked to the automatic socket blocking mechanism, which only allows access to two connector jacks for each function. Be certain to remove the appropriate plug from its respective jack before switching to and from the "A" functions. The socket blocking mechanism prevents the user from inadvertently turning the selector switch to impermissible functions after the measurement cables have been plugged in to the instrument.

4.1.1 Automatic Range Selection

The multimeter is equipped with auto-ranging for all measuring functions, except for temperature measurement, diode and continuity testing, and the MHz measuring function. Auto-ranging is active as soon as the instrument is switched on. The instrument automatically selects the measuring range which allows for highest possible resolution of the applied quantity. When the instrument is switched to frequency measurement, the previously selected voltage measuring range remains active.

The Auto-Ranging Function

The multimeter is switched automatically to the next higher range at ±(1999d+1d1200d) , and to the next lower range at ±(1100d-1d990d) .

Exception, capacitance measurement:

The multimeter is switched automatically to the next higher range at ±(199d+1d20d) , and to the next lower range at ±(10d-1d099d) .

4.1.2 Manual Measuring Range Selection

Auto-ranging can be deactivated and measuring ranges can be selected manually in accordance with the following table by pressing the MAN / AUTO button.

The desired measuring range can then be selected with the ◀ or ▷ scroll key.

The instrument is automatically returned to range selection when the MAN / AUTO key is pressed, the rotary switch is activated or the instrument is switched off and back on again.

4.1.3 Quick Measurements

Measurements performed using a suitable fixed measuring range are executed more quickly than those which utilize automatic range selection. Quick measurement is made possible with the following two functions:

• Manual measuring range selection, i.e. selection of the measuring range with the best resolution (see chapter 4.1.2).
  or
• With the DATA function (see chapter 4.4). In this way, the appropriate measuring range is selected automatically after the first measurement and the second measurement is executed more quickly.

The selected measuring range remains active for the subsequent series of measurements with these two functions.

4.2 Zero Offset / Relative Measurements

Depending upon deviation from the zero point, zero balancing or a reference value for relative measurements can be stored to memory:

Deviation from zero– With short-circuited measurement cables for V, Ω, A– With open input for capacitance unit of measure F	Display
0 to 200 digits ZERO ΔREL
>200 to 5000 digits ΔREL

The applicable reference or correction value is deducted individually for the respective measuring function as an offset from all subsequent measurements, and remains in memory until deleted, or until the multimeter is switched off.

Zero balancing and reference value adjustment can be used for auto-ranging, as well as for manual measuring range selection.

Zero Balancing

Plug the measurement cables into the instrument and connect the free ends to each other, except for capacitance measurement in which case the ends of the cables are not connected to each other.
Briefly press the ZERO | ESC key.
The instrument acknowledges zero balancing with an acoustic signal, and the "ZERO REL" symbol appears at the LCD. The value measured at the moment the key is pressed serves as a reference value.
Zero balancing can be cleared by once again pressing the ZERO | ESC key.

Note

As a result of TRMS measurement, the multimeter displays a residual value of 1 to 30 digits with short-circuited measurement cables as the zero point for V AC / I AC or V(AC+DC) / I (AC+DC) measurements (non-linearity of the TRMS converter). This has no influence on specified accuracy above 2% of the measuring range (or 3% in the mV range).

Setting the Reference Value

- Plug the measuring cables into the instrument and measure a reference value (max. 5000 digits).

Control Functions

Briefly press the ZERO | ESC key. The instrument acknowledges storage of the reference value with an acoustic signal, and the "ZERO ΔREL" or the "ΔREL" symbol appears at the LCD. The value measured at the moment the key is pressed serves as a reference value.
The reference value can be cleared by once again pressing the ZERO | ESC key.

Notes Regarding Relative Measurement

• Relative measurement effects the digital display only. The analog display continues to read out the original measured value.
• In the case of relative measurement, / F or AC quantities may also appear as negative values.

4.3 Display (LCD)

4.3.1 Digital Display

Measured Value, Unit of Measure, Type of Current, Polarity

The measured value with decimal and plus or minus sign appears at the digital display. The selected unit of measure and type of current are displayed as well. A minus sign appears to the left of the value during measurement of zero-frequency quantities, if the plus pole of the measured quantity is applied to the “⊥” input. The “D.d SP” parameter can be used to determine whether leading zeros will be appear or be suppressed at the measured value display (see chapter 6.4).

Overranging

If the upper range limit of 12,000 digits is exceeded “DL” (overload) appears at the display.

Exceptions: "OL" appears as of 1200 digits for capacitance measurement, and as of 5100 digits for diode testing.

4.3.2 Analog Display

Measured Value, Polarity

The analog display demonstrates the dynamic performance of a moving-coil mechanism. This display is especially advantageous for observing measured value fluctuation, and for balancing procedures.

Two different display modes can be selected in the "SET" menu with the help of the "R.d SP" parameter (see chapter 6.4):

- Bar graph - Pointer: The current measured value is tracked in real-time.

The analog scale displays a negative range of 2 scale divisions for the measurement of zero-frequency quantities, allowing for precise observation of measured value fluctuation around zero. If the measured value exceeds the negative range of 2 scale divisions, polarity is reversed at the analog display.

Scaling of the analog scale is automatic. This is very helpful for manual measuring range selection.

Overranging

Overranging in the positive range is displayed by means of the right triangle symbol.

Refresh Rate

In the bar graph and pointer modes, the analog display is refreshed 40 times per second.

4.4 Measured Value Storage: DATA (auto-hold / compare)

An individual measured value can be automatically “frozen” with the DATA function (auto-hold). This is useful, for example, when contacting the measuring points with the test probes requires your full attention. After the measuring signal has been applied and the measured value has settled in in accordance with the “condition” listed in the table below, the measured value is frozen at the digital display and an acoustic signal is generated. The test probes can now be removed from the measuring points, and the measured value can be read from the digital display. If the measuring signal falls below the value specified in the table, the function is reactivated for storage of the next value.

Measured Value Comparison (DATA Compare)

If the currently frozen value deviates from the first saved value by less than 100 digits, the acoustic signal is generated twice. If deviation is greater than 100 digits, only a brief acoustic signal is generated.

Note

The DATA function has no effect on the analog display, at which the current measured value continues to appear. However, when the digital display if “frozen”, the decimal point is fixed as well (fixed measuring range, symbol: MAN). The selected measuring range should not be manually changed as long as the DATA function is active.

The DATA function is deactivated by pressing and holding the DATA/MIN/MAX key (for approx. 1 second), when the measuring function is changed or when the instrument is switched off and back on again.

DATA Function	Press DATA / Min/Max	Condition Response from Instrument
		Measuring Function	Measuring Signal	Display		Acoustic
				MV Digital	DATA
Activate Brief blinks Once
Save (stabilized measured value)		V, A, F, Hz, MHz, %	>10% of R	Is dis-played	Static	Once Twice 2)

		Ω ➕	=OL

Exit Long				Is cleared	Is cleared	Twice

1) Reactivation results from falling short of specified measured value limits.
^2) Two acoustic signals are generated the first time a measured value is saved as a reference value. For subsequent data hold, two acoustic signals are only generated if the currently frozen value deviates from the first saved value by less than 100 digits.
Key: MV = measured value, R = measuring range

Control Functions

Example

The voltage measuring range is set manually to 10 V.

The first measured value is 5 V, which is stored to memory because it is greater than 10% of the measuring range (= 1 V), and is thus reliably above the background noise level. As soon as the measured values drops to less than 10% of the measuring range, i.e. amounts to less than 1 V which corresponds to removal of the test probes from the measuring point, the instrument is ready to store a new value.

4.4.1 Saving Minimum and Maximum Values - MIN/MAX Function

Minimum and maximum measured values applied to the measuring instrument's input after the Min/Max function has been activated can be "frozen" at the display. The most important use of this function is the determination of minimum and maximum values during long-term measured value observation.

The Min/Max function can be activated in all measuring functions.

The Min/Max function has no effect on the analog display, at which the momentary measured value continues to appear.

Apply the measured quantity to the instrument and set the measuring range with the MAN / AUTO key before activating the Min/Max function.

The Min/Max function is deactivated by pressing and holding the DATA/MIN/MAX key (for approx. 1 second), when the measuring function is changed or when the instrument is switched off and back on again.

Note

As opposed to the DATA function, the Min/Max function can also be used for temperature measurement.

Min/Max Function	Press DATA / Min/Max	Min. and Max. Measured Values	Response from Instrument
			Display		Acoustic Signal
			Measured Value Digital	Max. Min.
1 Activate and save	2 x brief are saved		Momentary measured value	Max and min.	2 x

3 Return to 1	Brief	Same as 1, stored values are not deleted	Same as 1	Same as 1	1 x
Stop Long Are deleted			Momentary measured value	Is deleted	2 x

4.5 Measurement Data Recording (METRAHIT X-TRA/OUTDOOR and SECULIFEHIT AM/MD only)

The METRAHIT X-TRA/OUTDOOR/SECULIFEHITAM/MD is capable of recording measurement data using an adjustable sampling rate for long periods of time in the form of measurement series. Data are stored to a battery backed memory module, and are retained even after the multimeter is switched off. The system acquires measured values relative to real-time.

Stored measured values can subsequently be read out with the help of METRAwin 10 software. The only prerequisite is a PC which is connected by means of an interface cable to the USB X-TRA bi-directional interface adapter, which is in turn plugged onto the METRAHIT X-TRA/OUTDOOR or SECULIFEHITAM/MD. See also chapter 7.

5 Measurements

5.1 Voltage Measurement

Notes Regarding Voltage Measurement

• The multimeter may only be operated with installed batteries or rechargeable batteries. Dangerous voltages are otherwise not indicated, and the instrument may be damaged.
• The multimeter may only be operated by persons who are capable of recognizing contact hazards and taking the appropriate safety precautions. Contact hazards exist anywhere, where voltages of greater than 33 V RMS may occur. The test probes may only be only gripped up to the finger guard. Do not touch the metallic test probes under any circumstances.
• Avoid working alone when taking measurements which involve contact hazards. Be certain that a second person is present.
• Maximum permissible voltage between the connector sockets, (9 and 10) and ground (8) is 1000 V for measuring category III, and 600 V for measuring category IV. Exception SECULIFE HITAM/HITMD: 600 V CAT III and 300 V CAT IV.
• Be prepared for the occurrence of unexpected voltages at devices under test (e.g. defective devices). For example, capacitors may be dangerously charged.
• No measurements may be made with this instrument in electrical circuits with corona discharge (high-voltage).

• Special care is required when measurements are made in HF electrical circuits. Dangerous pulsating voltages may be present.

• Be aware of the fact that dangerous voltage spikes are not displayed during measurement with the low-pass filter. We recommend measuring voltage without the low-pass filter first, in order to be able to detect any dangerous voltages.

• Be absolutely certain that the measuring ranges are not overloaded beyond their allowable capacities. Limit values are included in chapter 8, “Technical Data”, in the table entitled “Measuring Functions and Measuring Ranges” in the “Overload Capacity” column.

^2) Input resistance of approx. 1 MΩ. Erroneous displays resulting from capacitive coupling during voltage measurement in power supply systems are reduced to a minimum in this way.

5.1.1 Direct and Pulsating Voltage Measurement, V DC and V (DC+AC)

Note

Only to observe for METRAHIT TECH: Set the CL, P parameter to OFF in the current clip setup menu. Otherwise all measured values are displayed in amperes, and are corrected by the amount resulting from the selected transformation ratio for an interconnected clip-on current sensor.

In accordance with the voltage to be measured, turn the rotary switch to V or V.
Connect the measurement cables as shown. The “⊥” connector jack should be grounded.

Note

An intermittent acoustic signal warns the operator if the measured value exceeds the upper range limit in the 1000 V range.

Make sure that a current measuring range ("A") has not been activated when the multimeter is connected for voltage measurement! If the fuse's blowing limits are exceeded as a result of operator error, both the operator and the instrument are in danger! With the rotary switch in the V position, the multimeter is always set to the 1 V measuring range immediately after it is switched on. As soon a the MAN / AUTO key is pressed, and assuming the measured value is less than 90 mV, the multimeter is switched to the mV measuring range.

Measuring Ranges:

$$ \mathrm{V} =: 1 0 0 \mathrm{mV} \dots 1 0 0 0 \mathrm{V} $$

$$ V \approx : 1 0 0 \mathrm{mV} \dots 1 0 0 0 \mathrm{V} $$

5.7 Current Measurement

Notes Regarding Current Measurement

• The multimeter may only be operated with installed batteries or rechargeable batteries. Dangerous currents are otherwise not indicated, and the instrument may be damaged.
• Set up the measuring circuit in a mechanically secure fashion, and secure it against inadvertent breaks. Select conductor cross-sections and lay out connections such that they do not overheat.
• An intermittent acoustic signal warns of current greater than 10 A. An continuous acoustic signal warns of current greater than 16 A.
• The input for the current measuring range is equipped with a fuse link. Maximum permissible voltage for the measuring circuit (= rated voltage of the fuse) is 1000 V AC/DC. Use specified fuses only! The fuse must have a breaking capacity of at least 30 kA.
• If the fuse for the active current measuring range blows, "FUSE" appears at the digital display, and an acoustic signal is generated at the same time.
• If a fuse should blow, eliminate the cause of overload before placing the instrument back into service!
• Fuse replacement is described in chapter 9.3.
• Be absolutely certain that the measuring ranges are not overloaded beyond their allowable capacities. Limit values are included in chapter 8, “Technical Data”, in the table entitled “Measuring Functions and Measuring Ranges” in the “Overload Capacity” column.

Device and Measuring Parameters

7 Interface Operation (METRAHIT X-TRA/OUTDOOR/SECULIFEHIT AM/MD only)

The METRAHIT X-TRA/OUTDOOR is equipped with an infrared interface for the transmission of measurement data to a PC. Measured data are optically transferred through the instrument housing by means of infrared light to an interface adapter (accessory), which is attached to the multimeter. The adapter's USB interface allows for the establishment of a connection to the PC via an interface cable. Beyond this, commands and parameters can be transmitted from the PC to the multimeter as well. The following functions can be executed:

• Configuration and read-out of measuring parameters
• Measuring function and measuring range selection
• Start measurements
• Read out stored measured values

7.1 Activating the Interface

The interface is automatically activated for receiving operation (multimeter receives data from the PC) as soon as the interface is addressed by the PC, assuming that the “,56b” parameter has been set to “,ron” (see chapter 7.2), or the instrument is already switched on (the first command wakes up the multimeter, but does not yet execute any further commands).

The “continuous transmission” operating mode is selected manually as described below. In this operating mode, the instrument continuously transmits measurement data to the PC via the interface adapter, which can then be displayed with the help of a terminal program.

Starting Continuous Transmission Operation with Menu Functions

The ↓ symbol blinks at the display in order to indicate interface operation.

Stopping Continuous Transmission Operation with Menu Functions

The ↓ symbol is cleared from the display.

Automatic Activation and Deactivation of Transmission Mode Operation

If the sampling rate is 10 seconds or longer, the display is switched off automatically between samples in order to prolong battery service life. The only exception is when the multimeter is set to continuous operation.

As soon as an event occurs, the display is automatically switched back on.

7.2 Configuring Interface Parameters

r56b - status of the infrared receiver in the stand-by mode

There are two possible switching statuses for the infrared interface when the multimeter is switched off:

, non: IR appears at the display and the infrared interface is active, i.e. signals such as making commands can be received, and power is consumed even though the multimeter is switched off.

, roFF: IR does not appear at the display and the infrared interface is switched off, signals cannot be received.

(1, rStb = 1, roFF = default setting)

Addr - Address

If several multimeters are connected to the PC via an interface adapter, a separate address can be assigned to each instrument. Address number 1 should be selected for the first instrument, 2 should be assigned to the second and so forth.

(15 = default setting)

9 Maintenance and Calibration

Attention!

Disconnect the instrument from the measuring circuit before opening the battery compartment lid or fuse cover in order to replace batteries or fuses!

9.1 Displays – Error Messages

Message Function Meaning
FUSE	Current measurement Blown fuse
	In all operating modes Battery voltage has fallen below 1.8 V
OL	Measurement Indicates overflow

9.2 Batteries

Note

Removing the Batteries During Periods of Non-Use

The integrated quartz movement draws power from the batteries even when the instrument is switched off. It is advisable to remove the batteries during long periods of non-use for this reason (e.g. vacation). This prevents excessive depletion of the battery, which may result in damage under unfavorable conditions.

Note

Battery Replacement for METRAHIT X-TRA/OUTDOOR/SECULIFE HITAM/MD

Stored measurement data are lost when the batteries are replaced. In order to prevent data loss, it is advisable to backup your data to a PC with the help of METRAwin 10 soft-

ware before replacing the batteries.

The selected operating parameters remain in memory, although date and time must be reentered.

Battery

The current battery charge level can be queried in the “Info” menu:

:2.756866

Make sure that no battery leakage has occurred before initial start-up, as well as after long periods of storage. Continue to inspect the batteries for leakage at short, regular intervals.

If battery leakage has occurred, carefully and completely clean the electrolyte from the instrument with a damp cloth, and replace the batteries before using the instrument.

If the “” symbol appears at the display, the batteries should be replaced as soon as possible. You can continue working with the instrument, but reduced measuring accuracy may result.

The instrument requires two 1.5 V batteries in accordance with IEC R 6 or IEC LR 6, or two equivalent rechargeable NiCd batteries.

Replacing the Batteries

Attention!

Disconnect the instrument from the measuring circuit before opening the battery compartment lid in order to replace the batteries.

Set the instrument face down onto the working surface.
Turn the slotted screw on the lid with the battery symbols counterclockwise.
- Lift off the lid and remove the batteries from the battery compartment.
Insert two new 1.5 V mignon batteries into the battery compartment, making sure that the plus and minus poles match up with the provided polarity symbols.
When replacing the battery compartment lid, insert the side with the guide hooks first. Tighten the screw by turning it clockwise.
Please dispose of depleted batteries in accordance with environmental protection regulations!

9.3 Fuse (METRAHIT X-TRA/OUTDOOR, METRAHIT TECH, METRAHIT PRO and SECULIFEHITAM/MD only)

Testing the Fuse

The fuse is tested automatically:

• When the instrument is switched on with the rotary switch in the A position
• When the instrument is already on and the rotary switch is turned to the A position

- In the active current measuring range when voltage is applied. If the fuse is blown or has not been inserted, “FuSE” appears at the digital display. The fuse interrupts the current measuring ranges. All other measuring ranges remain functional.

Replacing the Fuse

If a fuse should blow, eliminate the cause of overload before placing the instrument back into service!

Attention!

Disconnect the instrument from the measuring circuit before opening the fuse cover in order to replace the fuse!

Set the instrument face down onto the working surface.
Turn the slotted screw on the cover with the fuse symbol counterclockwise.
- Lift off the cover and pry the fuse out using the flat side of the fuse cover.
Insert a new fuse. Make sure that the fuse is centered, i.e. between the tabs at the sides.
When replacing the fuse cover, insert the side with the guide hooks first. Tighten the screw by turning it clockwise.
→Dispose of the blown fuse with the trash.

Attention!

Use specified fuses only!

If fuses with other blowing characteristics, other current ratings or other breaking capacities are used, the operator is placed in danger, and protective diodes, resistors and other components may be damaged.

The use of repaired fuses or short-circuiting the fuse holder is prohibited.

Note

Testing the Fuse with the Instrument Switched On

After inserting the fuse with the instrument switched on, the instrument must be switched off briefly and then switched back on, or briefly switched to a non-current measuring range and then back to the "A" measuring range. If contact is poor or the fuse is blown, FUSE appears at the display.

9.4 Housing Maintenance

No special maintenance is required for the housing. Keep outside surfaces clean. Use a slightly dampened cloth for cleaning. Avoid the use of cleansers, abrasives or solvents.

9.6 Recalibration

The respective measuring task and the stress to which your measuring instrument is subjected affect the ageing of the components and may result in deviations from the guaranteed accuracy.

If high measuring accuracy is required and the instrument is frequently used in field applications, combined with transport stress and great temperature fluctuations, we recommend a relatively short calibration interval of 1 year. If your measuring instrument is mainly used in the laboratory and indoors without being exposed to any major climatic or mechanical stress, a calibration interval of 2-3 years is usually sufficient.

During recalibration* in an accredited calibration laboratory (DIN EN ISO/IEC 17025) the deviations of your instrument in relation to traceable standards are measured and documented. The deviations determined in the process are used for correction of the readings during subsequent application.

We are pleased to perform DAkkS or factory calibrations for you in our calibration laboratory. Please visit our website at www.gossenmetrawatt.com ( Company DAkkS Calibration Center or FAQs Calibration questions and answers).

By having your measuring instrument calibrated regularly, you fulfill the requirements of a quality management system per DIN EN ISO 9001.

* Verification of specifications or adjustment services are not part of the calibration. For products from our factory, however, any necessary adjustment is frequently performed and the observance of the relevant specification is confirmed.
