The gain and offset calibration results displayed for Channel 1, Channel 2, Channel 3
and Channel 4 are independent of the following conditions:
Time base
50 or 1 M input impedance
BWL on or off
Variable gain
Offset
Trigger mode and coupling
The internal calibration is checked at DC 1 M, and for the six gain settings :
2 mV, 5 mV, 10 mV, 20 mV, 50 mV, .1 V/div.
