When the instrument is under no load, select a channel and ensure the output current setting for this channel is not at zero.
-
Turn on the channel output, then ensure the channel is in Constant
Voltage output mode. -
Set some different voltage values on this channel; check if the actual
voltage value displayed is close to the set voltage value, and also that the actual current value displayed is nearly to zero. -
Check that if the output voltage can be adjusted from zero to the maximum rating.
When it is set to the maximum or minimum, a beep is heard, indicating that the limit has been reached. -
Current Output Inspection
The following steps check basic current functions with a short across the
power supply’s output:
