Output attenuation shall be set at 0 dB: go to Menu →
setting → amplier setting → Output attenuation
Gain shall be set to 32 dB and V
rms
shal be set according
to the amplier model: go to Menu → setting → amplier
setting → Input gain/Sens.
Channel output current offset calibration
Go to: Menu → Display → Output meters.
Feed channel with a 1 kHz @ 2 V

(2,82 V
peak
) sine wave
stationary signal.
No load on the output stage.
Check on the display if the V
rms
value has sets approx
80 V
rms
By acting on the channel potentiometer (Fig. 76) set the
output current at 0 the A
rms
.
By pressing the right push button, change the channel
and repeat the step.
