(3) Do not store or operate the instrument in high temperature
and high humidity environments.
(4) Keep the microphone dry and avoid severe vibration.

low humidity environment when not in use.
VII. Measurement
(1) Open the battery cover and install a 9V battery in the
battery compartment.
(2) Turn power ON and select the desired response time
and weighting. If the sound source consists of short
bursts, or the meter is only catching sound peaks, set
response to FAST. To measure average sound levels,
use the SLOW setting.
Select A-weighting for general noise sound level and
C-weighting for measuring sounds with high low
frequency content.
(3) Select desired level.
(4) Hold the instrument comfortably in your hand and point
the microphone at the suspected noise source. Read the
sound pressure level from the display.
(5) When MAX/MIN (maximum/minimum hold) mode is
chosen, the instrument captures and holds the maximum
and minimum noise level values indefinitely. The MAX/MIN
function operates on all settings, regardless of the
response time, weighting, or range.
Press the MAX/MIN button for two seconds to clear the
MAX/MIN reading. The “MAX/MIN ” symbol will disappear.
(6) Turn OFF the instrument and remove the battery when
not is use.
