Functional Tests

These functional test procedures include power-on and front panel function checks

as well as voltage and current mode operation checks.

Power-on

Check

1. Ensure that the front panel power switch is in the extended (OFF) position and

the voltage and current controls are in their fully counter-clockwise positions.

2. Ensure that the AC line voltage is within operating range.

3. Plug the line cord into a grounded AC outlet.

4. Push the power switch to turn on the power supply.

After a short power-on delay, the display and the red current mode LED lights. The

meter reading remains at zero.

For more about standard operations, see “Standard Operation” on page 35.

Voltage Mode

Operation

Check

1. Ensure that the front panel voltage and current control are turned fully

counter-clockwise.

2. Set the power switch to ON.

3. Rotate the current control one half-turn clockwise. Slowly rotate the voltage

control clockwise and observe the digital meter. Minimum control range should

be from zero to maximum rated output. Observe the bar graph meter to see that

it tracks as the voltage rises. Verify that the voltage mode indicator light is ON.

4. Set the power switch to OFF.

Current Mode

Operation

Check

1. Ensure that the front panel power switch is set to OFF.

2. Rotate the voltage and current controls fully counter-clockwise.

3. Rotate the voltage control one half-turn clockwise.

4. Connect a short circuit across the output terminals. Use leads of sufficient

current carrying capacity.

5. Set the power switch to ON.

6. Rotate the current control slowly clockwise. The control range should be from

zero to the maximum rated output

. Also check that the current bar graph meter

follows the rise in current and that the current mode indicator light is ON.

7. Set the power switch to OFF.

1. On 7.5-67 model, front panel current is limited to 30 A. Short the rear busbar terminals to test the

full current range is required.
