3.2.15.1.1 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 LCD displays
TIME@nn
(=_=_=)
where nn is the current memory location of the TIME function. Press CLEAR to exit
without changing setting. Press ENTER to validate existing location or enter the new location
and then press ENTER. The display now shows
TIMEval = n.n s
where n.n is the time value
set for the selected location. The default time interval for all 40 steps is 0.01 second. Enter new
value (between 0.01 and 655.35 seconds) and press ENTER to accept new value or press
CLEAR to exit without changing value. The unit returns to command entry status
(:_:_:)
.
Refer to PAR. 3.2.15.1.2 if accuracy of time values is important.
3.2.15.1.2 TIME INTERVAL ACCURACY
The accuracy of the time interval is ±1% through the entire time interval range.
3.2.15.2 RUNNING A PROGRAM
With the power supply in command entry status
(:_:_:)
, press RUN key. The LCD bottom line
indicates 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.
When the program is running, the LCD displays the actual voltage and current, however if all the
steps are programmed for 0.01 second, the LCD reads
*** RUNNING PROGRAM***
.
3.2.15.3 STEPPING THROUGH A PROGRAM
Programmed voltage is present at the output as steps are executed.
The STEP function is useful for examining a program that has just been created or edited before
running it 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 stepping 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 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).
