Frequently Asked Questions - SLM 10 PCE Instruments
How do I calibrate the PCE Instruments SLM 10 sound level meter?
To calibrate, use an external sound calibrator (94 dB at 1 kHz). Insert the microphone into the calibrator, turn the calibrator on, and adjust the calibration screw on the meter (if available) until the display reads 94.0 dB. For best accuracy, calibrate before each use.
What is the difference between A-weighting and C-weighting?
A-weighting filters low frequencies to approximate human hearing sensitivity, ideal for environmental noise. C-weighting has a flatter response, used for peak or impact noise. The SLM 10 allows you to select either weighting depending on your measurement purpose.
How do I change the battery on the SLM 10?
Turn off the meter and slide the battery cover open at the back. Replace the old 9V battery with a new one (type 6F22 or equivalent). Ensure correct polarity. Close the cover securely. Dispose of old batteries properly.
Can I use the SLM 10 outdoors?
Yes, but always attach the supplied windscreen to the microphone to reduce wind noise. Avoid using the meter in heavy rain or extreme humidity. The operating temperature range is 0°C to 40°C.
What do the 'MAX' and 'MIN' hold functions do?
Press the 'MAX' button to capture and hold the highest sound level measured since pressing. Press 'MIN' to hold the lowest level. Press again to return to real-time measurement. Use these functions to monitor peak or trough noise levels.
How do I set the time weighting (Fast/Slow)?
Press the 'F/S' button to toggle between Fast (125 ms response) for fluctuating sounds and Slow (1 s response) for steady noise. The current setting is usually indicated on the display.
What does the 'dB' resolution mean?
The SLM 10 measures sound pressure levels with a resolution of 0.1 dB. This means the display updates in increments of 0.1 dB, providing fine granularity for accurate readings.
Why does my meter show 'ERR' or a dashed display?
An 'ERR' message may indicate an overload (sound level above 130 dB) or an open microphone connection. Check that the microphone is properly attached and not blocked. Reduce the measurement range if applicable (though SLM 10 auto-ranges). If the problem persists, contact support.
Can I connect the SLM 10 to a computer?
The standard SLM 10 does not have a data output port. It is a standalone meter with manual reading. For data logging, consider the PCE-SLM 10 data logging version (if available) or use an external data recorder.
How do I clean and maintain the SLM 10?
Use a soft, dry cloth to clean the exterior. Do not use solvents or water. Store the meter in a dry, dust-free environment when not in use. Remove the battery if storing for extended periods. Calibrate regularly for accurate readings.
