Sound Level Meter (SLM-BTA, discontinued)

Specifications and User Guide

Troubleshooting

  • Primary Test (stand alone): Use the Power button to turn on the device. The LCD panel should display a reading of sound level, in dB.
  • Secondary Test (connected to an interface): Connect the device to an interface and run the data-collection program. For Logger Pro, open a file in the Probes & Sensors folder under the Experiment list. A reading should appear on the main screen of the data-collection program.

Note: The older Sound Level Meter does not auto-ID, which makes that version of the sensor incompatible with the Graphical Analysis app.
