III. Instrumentation
(1) Open the battery cover, and insert the
battery in position.
(2) Choosing a suitable adapter and plug
into the Sound-Level Calibrator.
(3) With suitable plug of microphone, and
plug into the adapter all the way down
of the Sound-Level Calibrator.
(4) Turn on power switch and set sound
level to 94dB or 114dB Position.
(5) Read the level on the microphone
instrument under test and adjust the
sensitivity control for the correct
indication of the Sound-Level
Calibrator level selected in step.
IV. Test Procedure
(1) Use the Sound-Level Calibrator as
specified in this manual; otherwise, the
protection provided by this meter may
be impaired.
(2) When using Sound-Level Calibrator,
environment noise level should less
then 10dB of output sound.
(3) Environment conditions
a. Altitude up to 2000 meters.
b. Relative humidity up to 90%.
c. Operation ambient 0~40 ℃
(32~104℉).
(4) Replace the battery for keep
measuring correctly, if LED indicator
light off.
(5) If long time not in use, we recommend
to take out the battery to decrease the
