Functional Tests
Before connecting the unit to an AC outlet, make sure that the power switch is in the
OFF position and that the voltage and current controls are turned fully counter
clockwise. Check that the J3 mating connector on the rear of the unit is in place with
jumpers connected for local operation as shown below. (This is the default
configuration as shipped from the factory). Connect the unit to a 230 Vac grounded
outlet and switch the unit on. After a short power on delay the front panel meters
should light up with both displays reading zero.

Operation
To check voltage mode operation, proceed as follows:
1. Connect a DVM, rated better than 0.5% accuracy, to the rear output terminals,
observing correct polarity.
2. Rotate the CURRENT control 1/2 turn clockwise. Slowly rotate the VOLTAGE
control clockwise and observe both the internal and external meters. Minimum
control range should be from zero to the maximum rated output. Compare the
test meter reading with the front panel voltmeter reading. Check that the green
voltage mode indicator led is ON.
3. Set the POWER switch to OFF.
