Selecting Frequency Weighting & Response Time
1.
When the meter is powered on, press and hold the POWER button
until SET1 appears, indicating the meter is in Frequency Weighting
selection mode.
2.
The default setting will be dBA. To toggle between dBA and dBC,
press the POWER button. ("A" Weighting should be selected for a
general noise sound level, and "C" Weighting should be selected for
measuring high level noise. "C" Weighting is a standard weighting
of the audible frequencies commonly used for the measurement of
Peak Sound Pressure Level. If the "C" Weighted level is much higher
than the "A" Weighted level, then there will be a large amount of low-
frequency noise.)
3.
Press and hold the POWER button to confirm your selection and skip
to SET 2 which allows a user to select the desired Response Time.
4.
Press the POWER button to toggle between FAST and SLOW. (If
the sound source consists of short bursts, set the response to FAST
(125ms). To measure average sound level, select SLOW (1 second).)
5.
Press and hold the POWER button to confirm your selection and
release it once the 3 second countdown begins to resume
normal operation.
Note: If "OL" appears on the LCD display, sound measurement is
currently out of range.
