Install the power supply and connect the load as described in Section 2. Installation. Ensure that the power supply is set up for local control as described in “Shipped Configuration (Local Control Mode)” on page 59. Then, set the output voltage and current limit at the front panel with the following procedure.

1.Turn both the voltage and current controls fully counter-clockwise.

2.Turn the AC power ON.

3.Press the STANDBY switch to its IN position to disable the power supply output. The red Shutdown (S/D) LED turns on.

4.Press and hold the V/I CHECK button to display the voltage and current control settings on the voltmeter and ammeter displays.

5.Adjust the voltage control to the desired voltage (the compliance voltage for applications using current mode operation).

6.Adjust the current control to the desired current limit setting.

7.Release the V/I CHECK button.

8.Press the STANDBY switch to its OUT position to apply power to the load. The S/D LED turns off.

Note:The control circuits have been designed to allow you to set output voltage and current up to 5% over the model-rated maximum values. The power supply will operate within these extended ranges, but we cannot guarantee full performance to specification.
