In Fig.38:
1 - LFA is on
2 - OSCILLOSCOPE mode
3 - the connected pair of wires
4 - "hot" buttons
5 - value of dividing the time axis (microsecond or millisecond)
6 - measured value of signal amplitude
7 - vertical scaling of the oscillogram
8 - gain value
9 - bias voltage value
After turning on the OSCILLOSCOPE, the previously set gain and bias voltage are used.
Correction is possible without shutting down the OSCILLOSCOPE.
