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.
