setup. (See Figure 2 on page 3.)
2.
Set the oscilloscope to:
vertical to 1 V/division
horizontal to 20 ms/division
averaging to 64
3.
Set the calibration generator to:
output frequency = 10 Hz
5 V
p-p
square wave output
output into 1 M
Ω
load
4.
Locate R9 (the DC gain adjustment).
WARNING.
To reduce risk of electric shock, use only the provided insulated adjustment tool when making adjustments.
Hazardous voltages may be present inside the compensation box.
