adjusting the knob.

Current output check
The following steps verify basic current functions with a short across the power
supply output.
1 Turn off the power supply.
2 Connect a short across the (+) and (–) output terminals of Output 1 with an
insulated test lead.
Use a wire size sufficient to handle the maximum current (refer to the American
Wire Gauge standard).
3 Turn on the power supply.
Ensure that all the outputs are disabled (the
OFF annunciator is turned on).
4 Enable the output for Output 1.
Press the
[Output 1 On/Off] button (the OFF annunciator for OUT1 turns off).
Notice that the display is in the meter mode.
NOTE
For subsequent power cycles, the power supply returns to the last power-off
state (when power is applied) by default.
