WARNING:
Before connecting wires to the output terminals, turn
OFF the power supply to avoid damage to the
instrument and the device under test (DUT). For
safety, load wires must have a wire gauge size large
enough to prevent overheating when the power
supply operates at maximum short circuit output
current. It will also prevent large voltage drops from
resistances in the wires.
2.3 Preliminary Check
Complete the following steps to verify that the power supply is ready for use.
1. Verify AC Input Voltage
Verify and check to make sure proper AC voltages are available to power the instrument.
The AC voltage range must meet the acceptable specification as explained in “2.1 Input
Power and Fuse Requirements”.
2. Connect Power and Self Test
Connect AC power cord to the AC receptacle in the rear panel and press the power
switch to the |(ON) position to turn ON the instrument. It will run through a self test
procedure with the screen shown in below:
Self-test Errors
The following errors will be displayed if self-test did not complete successfully:
