Programming
The device accepts this command:
a) Via both interfaces as device message “DCL” or “SDC” (setting
command)
Programming example (HP Basic):
OUTPUT 712;"DCL"
b) Via the IEC bus interface as addressed command SDC
(SELECTED DEVICE CLEAR)
Programming example (HP Basic):
CLEAR 712
c) Via the IEC bus interface as universal command DCL (DEVICE
CLEAR) for all bus users
Programming example (HP Basic):
CLEAR 7
DELAY – Output Off Delay for OCP
Functions
DELAY defines the delay time which must elapse before the
power output is switched off after current regulation has been
triggered (IOUT = ISET) with activated OCP function. If output
current drops back below the selected ISET value before this
delay time has elapsed, the shutdown sequence is aborted and is
started again the next time current regulation is triggered.
If the OCP function has not been activated, the DELAY setting is
of no significance.

DISPLAY, DISPLAY? – Activate / Deactivate Digital Displays
Functions
The 7-segment displays can be deactivated during remote
control operation with the DISPLAY function.
Applications
Since displays need not be refreshed when deactivated, slightly
shorter measuring and response times can be achieved during
interface operation.
Syntax
DISPLAY status
Parameter
Status
One of the following alternatives can be selected from
the group of possible text parameters:
Default setting after RESET (*RST): ON
Programming
Setting
Setting command: DISPLAY status
Example (HP Basic):
OUTPUT 712;"DISPLAY OFF"
! deactivate 7-segment display
Setting query
Query command:DISPLAY?
Response string:DISPLAY status
Possible response parameters for status:
"OFF" 7-segment display deactivated
"ON"7-segment display activated
Fixed response string length: 11 characters
Example (HP Basic):
OUTPUT 712;"DISPLAY?"
ENTER 712;A$
DISP A$
Display: DISPLAY ON
Comment
If the “REMOTE” operating mode is exited, the 7-segment display
is automatically reactivated.
FSET, FSET? – Sequence Function Parameter
Function
In addition to USET, ISET and TSET, FSET is the fourth parameter
for defining the sequence memory.
It determines which function will be executed upon transition to
the respective memory location.
Execution of the parameter is only possible during the course of a
running sequence (similar to the TSET parameter).
When the FSET parameter is transmitted, the current FSET
setting is determined and is saved to the respective specification
by means of the SAVE n command.
The parameters for the FSET command are also part of the
STORE command.
Setting Command
Syntax: FSET txt
Default setting
or after RESET (*RST): NF

OFF 7-segment display deactivated
