Setting Dwell Time
The dwell time is the amount of time that is delayed between each command during the
execution of an Auto Sequence program. The dwell time can be from 0 to 180 seconds and
can be changed during the program execution. The dwell time has a minimum step size of 1
second.
Command:
[:]PROGram[<channel>][:STEP]:DWELl {?|<dwell time> }
Where:
<dwell time > is an integer value from 0 to 180.
For Example:
:PROG:DWEL 12 Results in 12 seconds of wait time after each command is executed.
Storing an Auto Sequence Program
Loading a program into memory is done by using the
[: ] PROGram [<channel>] [:
RECord] : STARt
command. After the start command has been issued, the power supply will
record all subsequent commands into the auto sequence program buffer. The commands will
be recorded into the buffer until the
: PROGram [<channel>] [: RECord] : STOP
command is issued.
Commands:
[:]PROGram[<channel>][:RECord]:STARt
[:]PROGram[<channel>][:RECord]:STOP
Important:
If the start recording command is executed then any previously
stored Auto Sequence program is deleted.
For example:
:PROG:STAR
:VOLT 12
:OUTP ON
:PROG:DWEL 60
:OUTP OFF
:OUTP ON
:OUTP OFF
:PROG:DWEL 0
:PROG:STOP
This program will send a 12 V square wave with 120 seconds 50% duty cycle. When the
program is finished, the dwell time is restored to 0 seconds.
