Preparing the Power Supply
12 E3632A User’s Guide
3 Check that the front- panel voltmeter properly responds to
knob control for the 15 V/7 A range.
Turn the knob clockwise or counter- clockwise to check
that the voltmeter responds to knob control and the
ammeter indicates nearly zero.
4 Ensure that the voltage can be adjusted from zero to the full
rated value .
[1]
Adjust the knob until the voltmeter indicates 0 V, and
then adjust the knob until the voltmeter indicates 15.0 V.
Current output check
The following steps check the basic current functions with a
short across the power supply’s output.
1 Turn on the power supply.
The power supply will go into the power- on/reset state,
the output is disabled (the OFF annunciator turns on), the
15 V/7 A range is selected (the 15V annunciator turns on),
and the knob is selected for voltage control.
2 Connect a short across the (+) and (–) output terminals with
an insulated test lead.
3 Enable the output.
The OFF annunciator turns off and the 15V, OVP, and OCP
annunciators are lit. The CV or CC annunciator turns on
depending on the resistance of the test lead. The blinking
digit can be adjusted by turning the knob. Notice that the
display is in the meter mode. Meter mode means that the
display shows the actual output voltage and current.
4 Adjust the voltage limit value to 1.0 V.
Set the display to the limit mode (the Limit annunciator
will be flashing). Adjust the voltage limit to 1.0 V to
assure CC operation. The CC annunciator will turn on.
[1] You can use the resolution selection keys to move the flashing digit to the right
or left when setting the voltage.
