4 - Turn-On Checkout

Checkout Procedure

The test in this section checks for output voltage and current on the dc source.

NOTE:

To perform the checkout procedure, you will need a wire for shorting the output
terminals together.

The following procedure assumes that the unit turns on in the factory-default state. If you need more
information about the factory default state, refer to the *RST command in chapter 4 of the Programming
Guide. Note that the values shown in the Display column may not exactly match the values that appear
on the front panel of your unit.

If you have not already done so, connect the power cord to the unit and plug it in.

Explanation

1.

Turn the unit on. The dc
source undergoes a self-
test when you first turn it
on.

**********

ADDRESS 5

0.2410V     .0006A

During selftest, all display segments are briefly
lit, followed by the GPIB Address. The display
then goes into meter mode with the Dis
annunciator on, and all others off. In Meter mode
the 

*****V

 digits indicate the output voltage

and the 

*****A

 digits indicate the output

current. The flashing digit on the display
indicates the digit that will be affected if changes
are made to the displayed values using the rotary
control or the 

Ë

 and 

Ì

 keys. You will only see

the changes if the output is ON.

NOTE:

Press the Meter key to exit a menu at any time and return to meter mode. If the Err
annunciator on the display is on, press the 

Shift 

key followed by the 

Error

 key to see the

error number. See table 4-2 at the end of this chapter.

2.

Check that the dc source
fan is on

You should be able to hear the fan and feel the
air coming from the back of the unit.

3.

Press 

Voltage,

<2, 0>, Enter

VOLT 0.000

VOLT <20>

Programs the output to the selected voltage. After
the value is entered, the display returns to Meter
mode. Because the output has not been enabled,
the meter still indicates  0 volts.

4.

Press 

Output On/Off

<20.003V>

0.0006A

Turns the output on. The Dis annunciator should
be off and CV should be on.
