To check over current trip, press the menu key and the item key one time. This places the power

supply in data entry mode to set over current trip. Using the up/down arrow keys, enter an over

current trip set point at half the rating of the power supply. Once the over current trip set point

has been entered, press the enter key to save the information.

Press the start switch and slowly increase the current set point. Over current trip should operate

at the over current trip set point. The over current trip (OCT) indicator should turn on, the power

and current control indicators should turn off, and the supply should shut down. Press the clear

key. Now set the over current trip set point to maximum which is 110% the full scale rating of

the power supply. Again start the supply and observe that the power supply operates normally.

If any of these events do not occur, the supply is defective and should not be operated.

Depending on the circumstances, either warranty service or trouble shooting, as described in

Section 7.2, is required.
