Set calibration generator for Std Ampl output of 50 mV dc.
Set:
CH 1 VOLTS/DIV 10 mV
CH 1 Input COUPLING Dc
CHECK—the readout is between 49.0 mV and 51.0 mV.
Set CH 1 VOLTS/DIV to 0.1 V.
Set calibration generator for Std Ampl output of 0.5 V.
CHECK—the readout Is between 0.495 V and 0.505 V.
Set CH 1 VOLTS/DIV to 1 V.
Set
calibration
generator
for
Std

output
of
5
V.
CHECK—the readout Is between 4.95 V and 5.05 V.
Disconnect Std Ampl signal from the CH 1 input.
