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: 100Ω 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: 1KΩ approx.
Calibration
Frequent calibration is recommended and
is often required by noise standards and
directives.
1. Turn the meter ON
Put the meter in the 'A' weighting mode
2.
Put the meter in the 'SLOW' response mode
3.
4. Place the calibrator onto the microphone.
5. Turn the calibrator ON.
Adjust the meter's CAL potentiometer located
6.
on the side panel
so that the meter's display matches
the output of the calibrator (typically
94dB or 114dB).
