4.6 Output

4.6.1 AC OUT

The sound level meter is provided with two analogue outputs: DC OUT and AC OUT.
The DC OUT or AC OUT should be connected to another device or system using the
concentric cable. The input resistance of the terminal device or system should be
approx. 5 kΩ.
The AC OUT port is located at the bottom of the sound level meter. The microphone
signal is sent directly, without the possibility of adjustment. Maximum output voltage
is 5 V (±7 V ), maximum output current is ±15 mA.

☆ Hint: If the input resistance of the terminal device or system is not sufficient, use
an adapting system with impedance characteristics. The AC OUT can only be used
to record the own noise or monitor the values below the lower limit of the meter's lin-
ear measuring range.

4.6.2 DC OUT

The DC OUT is used to send an analogue DC signal being proportional to the meas-
urement result at a ratio of 10 mV/dB. For instance, if the result is 93.8 dB, the output
supplies a voltage of 938 mV. This option is recommended for filtering or creating the
average value of output signal to dampen the noise.

The Output menu allows you to choose the measurement data
sent to the DC OUT. For the level meter and 1/1-octave modes,
the options specify the DC output of the level meter and the
1/1-octave DC output.
The menu also offers the Printer option. Press the navigation
keys <▲> and <▼> to choose the option.
The Level Meter DC Out can be set as signal output for the level
meter mode. Press the navigation keys <▲>, <▼>, <◄>
and <►> to choose an option.
Filter: A, B, C and Z (flat)
Detector: Fast, Slow, Pulse
Mode: SPL, LEQ, Peak
1/1 Octave DC Out defines the output signal in the 1/1-octave
mode. The following options are available: LAeq, LBeq, LCeq,
LZeq, 31.5 Hz, 63 Hz, 125 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz,
4 kHz, 8 kHz, 16 kHz. Press the navigation keys <◄> and <►> to
choose an option.
