Current output check
The following steps check the basic current functions with a
short across the power supply’s output.
1 Turn 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 adjusted 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.
