more bars on the Battery Indicator the batteries will need to be replaced.
Remove the battery cover on the back and insert a new 9V Battery.
AC/DC Signal Output Jack
The meter is equipped with an AC/DC output jack to connect and
integrate with external systems. For example, the AC output can be used
with a frequency analyzer or oscilloscope to identify the frequency level
during a measurement. The DC output is used to identify the dB level
during a measurement.

AC Output Voltage Range
1 Vrms at FS (full scale)
(FS refers to the upper limit of the selected
dB level range. For example if 30-90dB is
the selected level range, 1Vrms = 90dB)
DC Output Voltage Range
10 mV/dB
