Factory Adjustment Procedure
To perform the factory adjustment procedure, do these steps:
1. Connect the oscilloscope to an AC power source.
NOTE. You must connect the oscilloscope and the test equipment to the same AC
power circuit. Connect the oscilloscope and test instruments into a common
power strip if you are unsure of the AC power circuit distribution. Connecting
the oscilloscope and test instruments into separate AC power circuits can result
in offset voltages between the equipment, which can invalidate the adjustment
procedure.
2. Locate the hole that provides access to the CAL switch on the rear panel.
