Current output check
The following steps check the basic current functions with a short across the
power supply’s output.
1Turn on the power supply.
Make sure that the output is disabled. The OFF annunciator is turned on.
2 Connect a short across the (+) and (–) output terminals with an insulated
test lead.
Use a wire size sufficient to handle the maximum current. Refer to Table 1-7 for
more information
3 Enable the output.
The CV or CC annunciator turns on depending on the resistance of the test
lead. Notice that the display is in the meter mode.
4 Adjust the voltage limit value to 1.0 V.
Set the display to the limit mode (the Limit annunciator will be flashing).
Adjust the voltage limit to 1.0 V to assure the CC operation. The CC
annunciator will turn on. To return to the normal mode, press the key
again or let the display time- out after several seconds.
5 Set the knob to the current control to check that the front panel ammeter
properly responds to the knob control.
Turn the knob clockwise or counter- clockwise when the display is in the meter
mode (the Limit annunciator is turned off). Check that the ammeter responds
to the knob control and the voltmeter indicates nearly zero (the voltmeter will
show the voltage drop caused by the test lead). The flashing digit can be
adjusted by turning the knob.
6 Ensure that the current can be ad justed from zero to the full rated value.

7 Turn off the power supply and remove the short from the output terminals.
[1] You can use the resolution selection keys to move the flashing digit to the right or left when setting
the current.
