Output Checkout
The following procedures check to ensure that the power supply develops its
rated outputs and properly responds to operation from the front panel. For
complete performance and verification tests, refer to the
Voltage output checkout
The following steps verify basic voltage functions with no load.
1
Turn on the power supply.
The power supply is in a power-on / reset state; the output is disabled (the OFF
annunciator turns on).
2
Enable the outputs.
The OFF annunciator turns off. Notice that the display is in the meter mode.
“Meter mode” means that the display shows the output voltage and current
limit.
3
Check that the front-panel voltmeter properly responds to knob control.
4
Turn the knob clockwise or counter clockwise to check that the voltmeter
responds to knob control and the ammeter indicates nearly zero.
5
Ensure that the voltage can be adjusted from zero to the full rated value by
adjusting the knob.
NOTE
If an error has been detected during the output checkout procedures, the
ERROR
annunciator will be turned on. See
Appendix A: List of Error Codes
information.
NOTE
When the power supply is turned on, the last memory will be shown on the
display.
