Frequently Asked Questions - SL100 SE VOLTCRAFT
How to change the battery of the SL100 SE sound level meter?
Turn off the device, loosen the screw of the battery compartment on the back, slide the cover off, and replace the old battery with a new 9 V battery (type 1604A). Close carefully.
What to do if the screen displays 'BAT'?
The 'BAT' symbol indicates low battery. Replace it immediately to avoid measurement errors. Use a 9 V battery type 1604A.
Why doesn't the device turn on?
Check the battery status and its proper contact. If the battery is discharged or incorrectly inserted, the device will not turn on. Replace the battery if necessary.
How to calibrate the SL100 SE sound level meter?
Turn on the device, select dBA, the Hi or Lo range and FAST time weighting. Connect the microphone to a sound calibrator set to 94 dB/1 kHz. The display should show 94.0 dBA. If not, open the battery compartment and adjust the trimmers A(Lo) or A(Hi) with a screwdriver until 94.0 dBA is displayed.
What is the difference between dBA and dBC?
The dBA filter simulates human ear sensitivity (attenuates low frequencies). The dBC filter is a linear measurement without filtering, representing the actual sound level. Use dBA for measurements close to human perception and dBC for technical measurements.
How to use the MAX function?
Press the 'MAX' button to activate maximum hold. The display shows 'MAX'. In continuous measurement, only the highest value is displayed. Press again to return to normal mode.
What does the 'OVER' display mean?
The 'OVER' display indicates that the measured value exceeds the selected measurement range. Switch to the other range (Hi/Lo) using the 'Hi/Lo' button. The Lo range covers 30-100 dB, the Hi range 60-130 dB.
How to clean the sound level meter?
Use a clean, lint-free, antistatic, slightly damp cloth. Do not use abrasive, chemical or solvent-based products. Avoid excessive moisture.
Can I use the sound level meter in the rain?
No. Measurements must not be carried out in the presence of water or high humidity, nor in stormy conditions. This could damage the device and falsify results.
How to dispose of the product at end of life?
Do not dispose of the device with household waste. It must be taken to a collection point for electrical and electronic equipment. Remove the battery and dispose of it separately according to local regulations.
