devclr
This command sets all sources to a zero state.
Usage
int devclr(void);
Details
This command clears all sources sequentially in the reverse order from which they were originally
forced. Before clearing all Keithley supported instruments, GPIB-based instruments are cleared by
sending all strings defined with the
kibdefclr
command.
devclr
is implicitly called by
clrcon
,
devint
,
execut
, and
tstdsl
.
For C-V testing, this command turns off the DC bias voltage.

2. Clears the matrix crosspoints by calling
clrcon
.
3. Clears the trigger tables by calling
clrtrg
.
4. Clears the sweep tables by calling
clrscn
.
5. Resets GPIB instruments by sending the string defined with
kibdefint
.
6. Resets the active instrument cards.
Instrument cards are reset in the following order:
