12. PRINTING DATA (OPTIONAL – PROVA 300XP PRINTER)
1. Using thermal printer cable connecting the meter and the printer.
2. Turn on the printer.
3. Setting the meter printing interval time.
Press
button turn off the meter.
Press and hold down
INTEG
TIME
button then turn on the meter, enter to sampling
interval time setting mode, the “ intr ” symbol is displayed.
A flashing cursor indicates the currently parameter (the second), press
and
buttons to set desired sampling interval time (from 5 second to 255
seconds).
Press
INTEG
TIME
button to stored the setting and exit this mode.
4. Press and hold down
button, then press
button turn on the meter, enter to
printing data mode.
13. OUTPUT CONNECTORS
13-1 AC Output:
An AC signal corresponding to the frequency-weighted signal is available at this
connector.
Output voltage: 2Vrms
±
100mVrms (scale upper limit)
Output impedance: approx. 5k
Ω
Load impedance:
≧
1M
Ω
The output voltage when the instrument is in calibration mode
(-6dB from scale upper limit, 1000Hz sine wave) is 0.5Vrms.
13-2 DC Output:
A level-converted DC signal generated by RMS detection and logarithmic
compression is available at this connector. The signal reflects the frequency and
time weighting settings of the instrument.
Output voltage: 10mV
±
0.1mV/dB
Output impedance: approx. 5k
Ω
Load impedance:
≧
1M
Ω
The output voltage when the instrument is reading 94dB is nominally 0.94V DC.
