5.
If the
button is not already illuminated, press it once and the display will show
the measured voltage at the output. This voltage may fluctuate slightly from the voltage
value entered in the previous steps.
6.
(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.
7.
Verify channels 2 and 3 according to steps 1 through 6.
Current Check
Follow the steps below to check current output of the power supply.
1.
Turn off all output channels (
not illuminated). The display will show the <
>
annunciator for all channels on the display.
2.
Short the (+) and (-) output terminals for CH1 with test leads or a shorting bar.
3.
Set the power supply to settings mode (press
so that it is not illuminated).
4.
Press the
button
first and then enter the value (i.e. 1.000 A) on the keypad and
press
the
button. The current display will now show the value you entered.
5.
Enable the output by pressing the
button. The <
> annunciator will be
replaced with a
next to the value entered indicating the power supply is in constant
current mode. This numeric value may fluctuate slightly from the current value entered
in step 4.
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.
Verify channels 2 and 3 according to steps 1 through 6.
8.
Press the power switch to turn off the power supply and remove the short on the output
terminals.
