VOLTS Shows present output voltage of the Agilent SAS.

AMPS Shows present output current of the Agilent SAS.

Status Annunciators

CV The Agilent SAS is in constant-voltage mode. (Applies in Fixed mode only)

CC The Agilent SAS is in constant-current mode.

Unr The Agilent SAS output is unregulated; the output is neither CV or CC.

Dis The Agilent SAS output is disabled.

OCP The Fixed mode overcurrent protection (OCP) function is enabled. (Applies in Fixed mode only.)

Prot A protection circuit has caused the Agilent SAS to shut down. (Press to determine the reason.)

Err An error has been generated as a result of remote operation. (Press to display the error code).

Cal The Agilent SAS is in calibration mode.

Shift The shift key has been pressed.

Rmt The Agilent SAS is in the remote mode (controlled over the GPIB).

Addr The Agilent SAS is addressed to listen or talk.

SRQ The Agilent SAS is requesting service from the controller.

ôOutput Rotary Controls

Voltage

knob Rotate clockwise to increase the output voltage or the voltage limit in constant current mode. Use to

rapidly set an approximate output value. (Applies in Fixed mode only)

Current

knob Rotate clockwise to increase the output current or current limit in constant current mode. Use to rapidly set

an approximate current value. (Applies in Fixed mode only)

í SYSTEM Keys

When the Agilent SAS is under remote control, press to enable local operation. This control can be

defeated by a lock-out command over the GPIB

Press to display the Agilent SAS’s GPIB address. You can change the address with the ENTRY keys

Use to display error codes generated during remote operation. (Select by pressing .)

Use to restore a previously saved Agilent SAS state. Use ENTRY keys through to specify which

location to recall.

Note: Location 0 may contain the Agilent SAS turn-on state. See "Turn-on operation" in this chapter.

Use to save the Agilent SAS’s present state to nonvolatile memory. (Select by pressing .)

Use ENTRY keys to specify the location where you want to store the state. You may use locations

through .

This unlabeled blue key is the Shift key. Press to access the shifted (alternate) key functions.
