Frequently Asked Questions - DL-161S VOLTCRAFT
How to replace the sound level meter battery?
Use a pointed and blunt object (e.g., mini screwdriver) to carefully remove the battery compartment cover. Insert a lithium battery 3.6 V 1/2 AA, observing polarity, then replace the cover until it clicks into place. Save data before removing the battery.
How to use the sound level meter without a computer?
The product can operate stand-alone. Point the microphone at the sound source from a distance of 1 m, then press and hold the record button to start or stop recording. Data is stored internally. Refer to the manual for details on stand-alone recording.
How to connect the sound level meter to a computer?
Make sure the software is installed (see next question). Plug the product into a USB port on the computer using the USB-A connector. Open the software and follow the on-screen instructions to establish the connection. Do not disconnect during a data transfer.
How to install the software provided with the sound level meter?
Insert the CD-ROM into the drive. Installation should start automatically. Otherwise, open the setup.exe file. Follow the on-screen instructions. For the latest version, download it from www.conrad.com/downloads by searching for the item number.
How to set up alarms on the sound level meter?
Alarms (high and low limits) are configured via the provided software. Open the software, connect the sound level meter, then access the alarm settings. You can set thresholds. Once configured, the ALM LEDs (red) indicate exceedance: 2 flashes for exceeding the high limit, 1 flash for the low limit.
What is the meaning of the LED indicators?
The ALM LED (red/yellow) indicates alarms and manual stop. The REC LED (green) indicates recording. For example: REC green flashing during measurement at the configured frequency; ALM red 2 flashes = exceeding high limit; ALM yellow flashes every 10 s after manual stop. Refer to the full table in the manual.
How to calibrate the sound level meter?
You need a class 2 acoustic calibrator (sold separately) generating a 94 dBA signal at 1 kHz. Connect the microphone to the calibrator, start the test signal, record it, then compare the measurement with the software. If a deviation is found, use the software to adjust. Refer to the software help for the calibration module.
What are the recommended operating conditions?
Operating temperature: 0 to +40 °C, relative humidity ≤ 90% non-condensing. Altitude ≤ 2000 m. Avoid direct sunlight, flammable gases, shocks and moisture. Storage: -10 to +60 °C, 10 to 75% RH.
How to clean the sound level meter?
Use a dry, lint-free cloth. Do not use harsh cleaning products, rubbing alcohol, or chemical solutions. Never immerse the device in water. Regular cleaning helps prevent malfunctions.
What to do if the sound level meter does not turn on?
First check the battery status: the red and green LED flashing every 10 seconds indicates a low battery. Replace it with a lithium battery 3.6 V 1/2 AA, observing polarity. If the problem persists, consult the manual or contact technical support.
