2. Enable the output by pressing , and the button will be lit. The OFF annunciator
will change to CV.
3. Using the numeric keypad or the voltage adjust knob and enter a voltage value. The
voltage display will now show the value you entered. If entering with numeric keypad,
press first, then enter the value and press .
4. If the button is not already lit, press it once and the voltage display will show
the measured voltage at the output, which may fluctuate slightly from the voltage value
entered in the previous step.
5. (Optional) You may also verify the output voltage by connecting the (+) and (-) terminals
to an external voltmeter. The measured value should match or be comparable to the
entered voltage value.
Current Check
Follow the steps below to check basic current output of the power supply.
1. Turn on the power supply. The display will show the OFF annunciator above the voltage
display. Be sure that the output is disabled (the should not be lit when it is off).
If not, press to disable output.
2. Short the (+) and (-) output terminals with test leads, shorting bar, or clip. (Refer to
“Table 2 - Wire Gauge Rating” to select appropriate test leads)
3. Using the numeric keypad or the current adjust knob, enter a small current value (i.e.
1.000 A). If entering with numeric keypad, press first, then enter the value and
press . The current display will now show the value you entered.
4. Enable the output by pressing , and the button will be lit. The OFF annunciator
will change to CC.
5. If the button is not already lit, press it once and the current display will show the
measured current at the output, which may fluctuate slightly from the current value
entered in step 3.
6. (Optional) You may also verify the output current by connecting the (+) and (-) terminals
to an external current meter capable of measuring the current that you set. The
measured value should match or be comparable to the entered current value.
7. Press the power switch to turn off the power supply and remove the short on the
output terminals.
