Product Information

Full details

This Draper Tools Noise Level Measuring Instrument (MPN: 31992) is designed for professionals who need precise sound level measurements, offering detailed analysis with frequency and time weighting filters. Its key benefit lies in its dual logging capabilities – long-term recording or real-time PC analysis, providing comprehensive data for environmental or workplace noise assessments. A potential caveat is the need for a separate noise level calibrator for accurate adjustment, which is not included.

FAQs

What is the difference between dB(A) and dB(C) weighting?

dB(A) weighting approximates the human ear's response to sound at typical listening levels, used for assessing noise annoyance and health risks. dB(C) weighting is flatter and captures more low-frequency sound, useful for measuring peak sound levels or assessing industrial noise.

Do I need to calibrate this device?

Yes, for accurate measurements, regular calibration with a standard noise level calibrator (sold separately) is recommended, especially for official or critical assessments.

What is included in the package?

The package includes the noise level measuring instrument, software, a USB cable, batteries, and a carrying case.

Can I use this device to measure very high noise levels?

The instrument is designed for professional use and covers a range of sound levels. Refer to the product manual for specific measurement range and maximum SPL (Sound Pressure Level) capabilities.

How do I transfer recorded data to my PC?

Connect the instrument to your PC using the supplied USB cable and use the included software to download the recorded data.

What kind of batteries does it use?

The instrument is supplied with batteries. Please refer to the device's manual for the exact battery type and replacement instructions.

Can the analogue outputs be used for continuous monitoring?

Yes, the analogue DC and AC outputs can be connected to external logging or monitoring equipment for continuous data acquisition.

Troubleshooting

Device does not power on

Ensure batteries are correctly installed and charged. Check battery contacts for corrosion.

No reading on the display

Verify that the microphone is not obstructed. Check that the correct measurement mode (dB(A) or dB(C), Fast/Slow) is selected.

PC software does not detect the device

Ensure the USB cable is securely connected at both ends. Reinstall the USB drivers and the software. Try a different USB port.

Inaccurate readings

Calibrate the device using a certified noise level calibrator. Ensure the device is not used near strong electromagnetic interference sources.

Long-term recording not saving data

Check the available storage space on the device. Ensure the recording function was properly initiated.
