The following steps check 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 on.
2 Connect a short across (+) and (–) output terminals with an
insulated test lead. Use a wire size sufficient to handle the
maximum current (refer to the American Wire Gauge
standard).
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 volt.
Set the display to the limit mode. Adjust the voltage limit to
1.0 V to assure CC operation. The CC annunciator will be
turned on. To go back to 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 knob control.
Turn the knob clockwise or counter clockwise when the
display is in the meter mode (the Limit annunciator is off).
Check that the ammeter responds to knob control and the
voltmeter indicates nearly zero (the voltmeter will show the
voltage drop caused by the test lead).
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.
