cvu_custom_cable_comp
This command determines the delays needed to accommodate custom cable lengths.
Usage
cvu_custom_cable_comp(int instr_id);
The instrument identification code of the CVU (
)
Details
The custom cable length measure gathers a specific set of timing coefficients to be applied during the
C-V testing for a custom length cable. They are used to compensate the calibrated measurements
made from the CVU.
Custom cable lengths are any lengths that are not 0 m, 1.5 m, or 3 m.
Once this command is run, these values are applied if you select a cable length of Custom in Clarius
Tools > CVU Connection Compensation.
Possible return values are:
• 0: OK
• -907: LPOT/LCUR fail
• -908: HPOT/HCUR fail

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.
