Meter Placement
The meter can be used Handheld, Wall mounted, Desk mounted or Tripod mounted. For
wall mount operation, orient the microphone perpendicular to the wall to minimize the
affect of acoustic reflections. For desk mounting, extend the rear legs and lock in place
with the hinged locks. The tripod mounting nut is located on the bottom of the unit.
Remote Microphone (optional)
The optional 15’ remote microphone cable can be used to place the microphone in one
location while viewing the dB levels and/or generating a high limit alarm at another
location. To remove the microphone, unscrew the holding collar and lift the microphone off
the connector. The extension cable can then be plugged into the matching connectors.
Calibration should be performed after the cable is installed.
Alarm Output (optional)
The alarm output drives the optional Remote Alarm Relay Module (cable and relay) when
the LIMIT set point is exceeded. The relay module can be used to power external warning
signs, “QUIET” signs or other indicating devices when the sound level is higher than the
programmed limit. Refer to the manual supplied with the module for connection
information.
