2.4 Initial 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 230Vac grounded outlet (115Vac outlet if previously
configured for 115Vac operation as per instructions in section 2.3.1) and switch the unit on. After a short power
on delay the front panel meters should light up with both displays reading zero.

Connector J3 Configuration for Local Operation
To check voltage mode operation, proceed as follows:
• Connect a DVM, rated better than 0.5% accuracy, to the rear output terminals, observing correct
polarity.
• 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.
• Set the POWER switch to OFF.
To check current mode operation, proceed as follows:
• Rotate the VOLTAGE and CURRENT controls fully counterclockwise.
• Rotate the VOLTAGE control 1/2 turn clockwise.
• Connect a high current DC ammeter across the rear output terminals, observing correct polarity.
Select leads of sufficient current carrying capacity and an ammeter range compatible with the unit's
rated current output. The ammeter should have an accuracy of better than 0.5%.
• Set the POWER switch to ON.
• Rotate the CURRENT control slowly clockwise. The control range should be from zero to the
maximum rated output. Compare the test meter reading with the reading on the front panel ammeter.
Check that the red current mode indicator led is ON.
• Set the POWER switch to OFF.
