2.7 Output verification

The following procedure verify that the power supply outputs the correct
voltage and current levels and properly responds to entries from the front
panel.

Press Power key to turn on the power supply.
On/Off
Press key to enable the output.
Set the voltage value.
Adjust the voltage, then press
METER mode), make sure that the set value and output value are same,
and if the current displayed on the VFD is nearly 0A.
Make sure the voltage can be adjusted from zero to the maximum rated
value.
Check the other two channels by the same method.
NOTE
Meter Meter
when key is gray, the power supply is in SET mode, then the VFD displays the set
voltage and current; when the key is lit, then the power supply is in METER mode, the actual
voltage and current display on the VFD. When the output is OFF, the "OFF" indicate will display
at the current display area.
Press Power key to turn on the power supply.
On/Off
Press to disable the output, ensure the output is OFF.
Connect a short across (+) and (-) output terminals with an insulated test
lead, use a wire sufficient to handle the maximum current.
Adjust the voltage value to 1V.
On/Off
Press to enable the output.
Adjust the current.
Set some different current values, in METER mode, check whether the
voltage value on VFD is near 0v, and the current on it is close to the value
you set.
Make sure that the current can be adjusted from 0 to full rated value.
Disable the output and then remove the short wire.
Check the other two channels by the same method.
