The LCD top line shows
LOC
to indicate local mode,
aa
bb
where aa is the memory location
just executed, bb is the NEXT STEP location, and shows
CV
(constant voltage) or
CC
(constant
current) to indicate the actual operating mode. The LCD bottom line shows the output voltage
and current measurements for the location just executed, and
(:_:_:)
indicates command sta-
tus. Press
STEP
to execute location bb. The LCD will again display the location just executed,
voltage and current measurements, and the NEXT STEP location. Continue to press
STEP
to
execute the program one step at a time. The
OUTPUT ON/OFF
key can be used to turn the out-
put on or off when in step mode.
Press
CLEAR
, or
RESET
to exit Step function:
CLEAR
keeps the output at the values estab-
lished by that step (as permitted by the load).
RESET
restores the power on defaults (Figure 3-
1).

CYCLING A PROGRAM
To cycle a program, modify the program (see PAR. 3.2.16.1) and go to the last memory location
to be executed and set the NEXT STEP address to the Starting address, causing the program to
loop and repeat indefinitely. For example, if the last location is 14, and the starting location is 05,
press
EDIT PROG
, enter
14
, then press
ENTER
. Press
until LCD reads
ViewVAL Mem14
NEXT STEP (=_=_=)
. Enter
5
and press
ENTER
. When the program runs, it will start at loca-
tion 05, continue to 14, then loop back to the location 05, and repeat indefinitely.
3.2.16.5
RUNNING A PROGRAM ONCE
To set up a program to stop after running once, modify the program (see PAR. 3.2.16.1) and go
to the last memory location to be executed and set the NEXT STEP address to 0. For example,
with the power supply in command entry status
(:_:_:)
, press
EDIT PROG
. Enter the last
memory location you want executed (e.g. 14), then press
ENTER
. Press
key until LCD reads
ViewVAL Mem14 NEXT STEP (=_=_=)
. Enter 0 and press
ENTER
. The program will now
stop after memory location 14 is executed. When the program stops, the power supply will con-
tinue to provide the output specified by the last location (in the above example, location 14).
3.2.16.6
STOPPING A RUNNING PROGRAM
There are three ways to stop a program that is running:
• Press CLEAR key: the program stops after finishing the step (location) that was being
executed when the key was pressed. The power supply output remains at the values
specified by that step.
• Press RESET key: The program stops immediately and power on defaults are restored
(see PAR. 3.2.8).
• Press OUTPUT ON/OFF key: the output is disabled (programmed to zero) and the pro-
gram immediately stops at the step (location) that was being executed when the key
was pressed. Pressing the OUTPUT ON/OFF key again restores the output to the val-
ues specified by the step in effect when the program was stopped.
3.2.16.7
SAMPLE PROGRAM
Table 3-5 shows a sample program designed to cycle continuously; if the NEXT STEP value for
location 3 is set to 00, the program will run once and stop.
