Full scale is defined as 32 mV on the 2 mV/div range and the 1 mV/div range.
Full scale on all other ranges is defined as 8 divisions times the V/div setting.
d Press the [Acquire] key.
e Then press the Acq Mode softkey and select Averaging.
f Then press the #Avgs softkey and set it to 64.
Wait a few seconds for the measurement to settle.
4 Add a measurement for the average voltage:
a Press the [Meas] key.
b Press Source; then, turn the Entry knob (labeled
on the front panel) to select the channel you are
testing.
