Basic Tests
The functional test procedures described in this section include power-on and front
panel function checks as well as voltage and current mode operation checks.
Equipment
Required
• Digital Voltmeter (DVM) rated better than 0.05% accuracy.
• DC shunt 1mV/A ( ± 0.25%) with connecting wire. The recommended current
ratings for the DC shunt and the wire must be at least 10% more than the output
current of the power supply.
WARNING
The factory setting for Power ON is 0V and 0A. These settings can be changed by
end users. If you suspect that the power supply has been used by someone else
since it was received from the factory, be prepared for the unit to power ON with a live
DC output.
