3) Set the voltage value
Set a different voltage value.
Make sure that the set value and output value are the same. Also check if the
output current value is zero or close to zero A.
4) Ensure that the voltage can be adjusted from zero to the maximum rated value.
Current Output Check
The following steps check the basic current functionality by shorting the power supply’s output.
1) Turn on the power supply.
2) Disable the output by pressing the
Out on/off
. The ON annunciator is turned off.
3) Connect a short across the (+) and (-) output terminals with an insulated test lead. Use a wire size
sufficient to handle the maximum current.
4) Enable the output.
5) Adjust the voltage value to 1.0 volt. Ensure that the CC annunciator is lit (power supply is in CC
operation mode)
6) Adjust the current value. Set a different Current value and check if the actual Current value is the same
as the set Current value. Also verify that the output voltage value is nearly zero.
7) Ensure that the current can be adjusted from zero to the full rated value.
8) Turn off the power supply and remove the short wire from the output terminals.
1.5 If the power supply does not turn On
Use the following steps to help resolve problems you might encounter when turning on the instrument.
1. Verify that there is AC power applied to the power supply.
Verify that the power cord is firmly plugged into the power receptacle on the rear panel of the power supply.
Make sure the power outlet you are using is working properly and verify that the power supply is turned on.
2. Verify the power-line voltage setting.
Make sure the voltage selector switch is set according to the present line voltage (110 VAC or 220 VAC).
Change the voltage setting if it’s not correct.
3. Verify that the correct power-line fuse is installed.
