ANALOG OUTPUTS
The meter is equipped with an analog output feature. The analog output jack
is located on the meter’s side panel and requires a 3.5mm stereo phono plug.
(1-AC Output, 2-DC Output, 3- Ground)
AC analog output
The AC output is a retransmitted representation of the meter’s measurement (note that the output
factors in the meter’s frequency weighting selection ‘A’ or ‘C’).
Output voltage: 1Vrms at full scale of the selected range.
Output impedance: 100
Ω
approx.
DC analog output
The DC output signal reflects the frequency weighting selected (‘A’ or ‘C’).
Output voltage: 10mV (±1mV) per displayed dB.
Output impedance: 1K
Ω
approx.
Calibration
Frequent calibration is recommended and is often required by noise
standards and directives.
1.
Turn the meter ON
2.
Put the meter in the ‘A’ weighting mode
3.
Put the meter in the ‘SLOW’ response mode
4.
Place the calibrator onto the microphone.
5.
Turn the calibrator ON.
6.
Adjust the meter’s CAL potentiometer located on the side panel
so that the meter’s display matches the output of the calibrator
(typically 94dB or 114dB).
Battery Replacement
1. The battery icon will appear on the display when the battery needs replacing.
2.
Turn the meter OFF and slide the rear battery cover off.
3.
Install the 9V battery and replace the cover.
