sound meter that is user-calibrated and has a ½" or
1" microphone. Features 2-point calibration at 94 dB
and 114 dB, and a low battery indicator. Comes with
instructions, 9V battery and a carrying case.

3. OPERATING PROCEDURE
Note: For accurate calibration, background noise
should be less than 10 dB.
• Determine the sound meter’s microphone size.
• Use the 1/2" Microphone Adapter (2) when
calibrating a 1/2" diameter microphone.
• When calibrating a sound meter with a 1"
microphone, pull off the 1/2" Microphone Adapter
(2) to use the 1" Microphone Insertion Socket (1).
• Fully insert the sound meter’s microphone into
the insertion socket.
• Use the 94dB/114dB/Off Slide Switch (4) to turn
the calibrator on and select either 94 dB or 114 dB.
• Be sure the sound meter is set to an appropriate
scale to measure a matching sound of 94 dB
or 114 db.
• Adjust the sound meter according to it’s
calibration instructions.

4. BATTERY INSTALLATION AND REPLACEMENT
• Replace the battery if the Power Indicator (3) does
NOT light when 94dB/114dB/Off Slide Switch (4) is
in the 94 dB or 114 dB position and/or when there is
no audible tone.
• Unscrew the Battery Compartment Ring (5).
• There are wires connected to the Battery
Compartment (6), so SLOWLY lift the center to
access the battery.
• Insert a fresh 9V Alkaline battery.
• Replace the Battery Compartment (6) and tighten
the Battery Compartment Ring (5).
• A fresh Alkaline battery should power your calibrator
for approximately 20 hours of use.
• Remove the battery if the calibrator will not be in use
for a long period of time.
• Tampering with the internal circuitry will void
your warranty.
