Output Check
Voltage Check
Follow the steps below to check basic voltage output with no load connected.
1.
Turn on the power supply. The display will show the
OFF
annunciator above the voltage
display.
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
on the rear panel to an external voltmeter. The measured value should match or be
within 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
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 either the (+) and (-)
terminals on the rear panel to an external current meter capable of measuring the
current that you set. The measured value should match or be within the entered
current value.
