jDisplaykAnnunciators

14-character vacuum fluorescent display for showing output measurements and programmed values.

Annunciators light to indicate operating modes and status conditions: CV The dc source output is in constant-voltage mode.

CCThe dc source output is in constant-current mode. Unr The dc source output is in an unregulated state. Dis The dc source output is disabled (off).

OCP The overcurrent protection state is enabled.

Prot One of the dc source's output protection features is activated. Cal The dc source is in calibration mode.

Shift The Shift key is pressed to access an alternate key function. Rmt The selected interface (HP-IB or RS-232) is in a remote state. Addr The interface is addressed to talk or to listen.

Err There is a message in the SCPI error queue.

SRQ The interface is requesting service from the controller.

lRotary Control

mOutput Connectors

The rotary control lets you set the output voltage or current as well as menu parameters. Press á and â to select the resolution, then adjust the value with the knob.

Optional front panel binding posts let you connect loads to the front of the unit. Before using the front panel binding posts, make sure that the output terminals are jumpered for Local sensing.

nLineoSystem KeyspFunction Keys

This turns the dc source on or off.

The system keys let you:

Return to Local mode (front panel control) Set the dc source HP-IB address

Set the RS-232 interface communication baud rate and parity bit Display SCPI error codes and clear the error queue

Save and recall up to 4 instrument operating configurations

Function access command menus that let you: Enable or disable the output

Select metering functions

Program output voltage and current Display the protection status state Set and clear protection functions Set the output state at power-on Calibrate the dc source

p and q scroll through the front panel menu commands

q Entry Keys	Entry keys let you:
	Enter programming values
	Increment or decrement programming values
	ã and ä select the front panel menu parameters
