annunciator turns off.

Press

 

AMPS 1.000

Dis turns off and CC turns on. The output current is restored.

 

 

 

 

If you have a shorting wire of sufficient capacity, you may continue testing up to the maximum rated current of the power supply (see "Performance Specifications"). When finished, go to the next step.

Press

 

AMPS 0.000

 

Dis turns on and output current drops to zero.

 

Turn off the power supply and remove the short from the output terminals.

Checking the Save and Recall Functions (All Models)

The Series 668xA/669xA supplies have four nonvolatile memory storage locations (0 through 3). The supplies of all other series have five (locations 0 through 4). Proceed as follows:

■Make certain that the output is on (Dis annunciator is off).

■ Set the voltage output to 5 by pressing

.

■

Save this value to location 1 by pressing

.

■

Return the output voltage to 0 by pressing

(This step is based on the fact that a newly shipped power

supply has the *RST parameters stored in location 0 (see "Chapter 5 - Front Panel" for more information).

■Press and notice that the output voltage returns to the value stored in location 1.

Determining the GPIB Address (All Models)

When the power supply is turned on, the display shows ADDR n, where n is the power supply GPIB address. Any time you

want to see the address, press .

The display will indicate ADDR 5, which is the factory default. If the address has been changed, then a different number will appear (see “Setting the GPIB Address” in “Chapter 5 - Front Panel”).

In Case of Trouble

Line Fuse

If the power supply appears "dead" with a blank display and the fan not running, first check your power source to be certain line voltage is being supplied to the power supply. If the source is normal, the power supply line fuse may be defective. On
