The top line of the LCD indicates the active memory location, e.g.
ViewVAL Mem
where n
is the memory location previously chosen. The bottom line of the LCD indicates the parameter
on the left
(Iset
,
Vset
,
OVset
,
OCset
,
TIMEval
,
NEXT STEP
), the parameter’s value on the
right, and data entry status
(=_=_=)
in the middle. To modify time values see PAR.3.2.16.1.1.
Press ENTER to accept displayed value, or enter new value and press ENTER to accept new
setting (the LCD displays the next parameter). Press CLEAR to exit Program Edit mode without
changing value. Use
or key to scroll forward or backward to view next or previous param-
eter or memory location. For a program to run once, then stop, see PAR. 3.2.16.6; to cycle a
program continuously, see 3.2.16.4. After all program values have been set, press CLEAR or
ENTER to exit Program Edit mode. Setting up a program can be made easier by copying the
Memory Location Worksheet (Table 3-5) and filling in the values before programming the power
supply.
3.2.16.1.1 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 the existing location or enter the new loca-
tion 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
(:_:_:)
.
3.2.16.1.2 TIME INTERVAL ACCURACY
The accuracy of the time interval is ±1% through the entire time interval range.

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***
.
3.2.16.3 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.
