To adjust the power supply

The oscilloscope power supply has both a +3.3 V adjustment, and a

+5.1 V / -5.2 V balance adjustment. Other oscilloscope voltages are based on the +3.3 V adjustment.

In this procedure, you will use a digital multimeter to measure the +3.3 V and +5.1 V / -5.2 V test points, and adjust the power supplies to be within tolerance, if necessary.
