OUTPUT

Annunciators

Power Supply Status Annunciators

(These five annunciators indicate the status of the power supply).

Indicate which output channel has been selected for front panel control and/or display. (Only one output annunciator can be on at a time.)

CV - Indicates that the selected output channel is in the constant voltage mode.

CC- Indicates that the selected output channel is in the positive constant current mode ( + CC) or the negative current limit ( - CC) mode.

UNR - Indicates that the selected output channel is unregulated; i.e., it is not regulated by CV or CC control loops.

OCP ENBLD - Indicates that the overcurrent protection function for the selected channel is enabled.

ERR - Indicates that a programming or hardware error has occurred and that the ERR bit in the serial poll register has not been cleared.

System Control Keys (These four control keys affect the entire power supply and are independent of the output selected).

ADDR - Displays the power supply’s GP-IB address. You can change the address using the numeric entry keys. You cannot query or change the address remotely (over the GP- IB).

ERR- Displays a programming or hardware error message and clears the ERR bit in the serial poll register.

STO - Used in conjunction with the numeric entry keys to store the present output voltage and current settings for all outputs in the specified internal register (1 to 10). Each register contains voltage and current settings for all output channels.

RCL - Used in conjunction with the numeric entry keys to recall the settings from the specified internal register (1 to 10). All outputs are set to the recalled values.
