Function or Indication

Display

Shows present output voltage of the power supply.

Shows present output current of the power supply.

Status Annunciators

The power supply is in constant-voltage mode. The power supply is in constant-current mode.

The power supply output is unregulated (output is neither CV or CC). The power supply output is disabled.

The overcurrent protection function is enabled.

A protection circuit has caused the power supply to shut down. (Press to determine the reason.)

An error has been generated as a result of remote operation. (Press to display the error code). The power supply is in calibration mode.

The shift key has been pressed.

The power supply is in the remote mode (controlled over the GPIB). The power supply is addressed to listen or talk.

The power supply is requesting service from the controller.
