Indicator
Function or Indication
Display
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.
