3.3.14.1.1 MODIFYING PROGRAMMED TIME INTERVAL
The TIME key offers a quick and easy way to change the time for any memory location. With the
power supply in command entry status , press TIME key. The unit displays
TIME @ mem =
01
indicating the current step to be changed. To change a different step, enter the step number
using the numeric keys. To proceed, depress ENTER. The LCD displays
TIMEval nn
where
nn is the time value set for the selected location. Press ENTER to accept displayed value, or
enter new value (between 0.01 and 300 seconds) and press ENTER to accept new value or
press CLEAR to exit without changing value. The unit returns to command entry status .
The accuracy of the time interval is +5% (specified time interval may be exceeded by a maxi-
mum of 5%).
3.3.14.2 RUNNING A PROGRAM
With the power supply in command entry status , press RUN key. The LCD bottom line indi-
cates the start address of the program. Press ENTER key to run the program starting with that
address. To change the starting address, enter new value and press ENTER to run the pro-
gram. Press CLEAR to exit without running the program
3.3.14.3 STEPPING THROUGH A PROGRAM
The STEP function is useful for examining a program that has just been created or edited before
running in real-time. With the power supply in command entry status , press STEP key. The
LCD bottom line indicates the start address of the program; press ENTER to begin stepping at
that address. To change the starting address, enter new value and press ENTER to begin step-
ping at the new address, press CLEAR to exit without stepping through the program.
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 status.
Press STEP to execute location bb. The LCD will again display the location just executed, volt-
age and current measurements, and the NEXT STEP location. Continue to press STEP to exe-
cute the program one step at a time, or press CLEAR to exit Step function.
3.3.14.4 CYCLING A PROGRAM
To cycle a program, modify the program (see PAR. 3.3.14.1) 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.
3.3.14.5 RUNNING A PROGRAM ONCE
To set up a program to stop after running once, modify the program (see PAR. 3.3.14.1) 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 continue to
provide the output specified by the last location (in the above example, location 14).
