XI. MEASUREMENT
(1) Open battery cover and install a 9V battery in the battery
compartment.
(2) Turn the power on and select the desired response Time and Weighting.
If the sound source consists of short bursts or only intermittent sound
peaks, set the response to FAST. To measure an average sound level,
use the SLOW setting. Select A-weighting which filters out low
frequencies to approximate the response of the human ear at lower
SPL's. C - Weighting filters less low frequencies to approximate the
response of the human ear at higher SPL's. (a flatter response.)
(3) Select desired Level Range.
(4) Hold the instrument comfortably in your hand or mount to a tripod and
point the microphone at the suspected noise source. The sound
pressure level will be displayed.

instrument captures and holds the maximum and minimum noise
level for a long period using any of the time weightings and ranges.
Press the MAX /MIN button for 2 seconds to clear the MAX/MIN
reading. MAX/MIN ” symbol disappears.

be used for an extended period.
