smuX.contact.calibratelo()
This function calibrates the low/sense low contact check measurement. This function is not available on the
Models 2604B/2614B/2634B.

Function Yes
Usage
smuX.contact.calibratelo(cp1Measured, cp1Reference, cp2Measured, cp2Reference)
X
cp1Measured
cp1Reference
cp2Measured
cp2Reference
Details
Contact check measurement calibration does not require range information.
Typically, calibration points one and two are near 0 Ω and 50 Ω, respectively.
All four measurements (cp1Measured, cp1Reference, cp2Measured, and cp2Reference) must be made
with the active calibration set. If not, corruption of the calibration constants may result.
The new calibration constants are activated immediately but are not written to nonvolatile memory. Use
smuX.cal.save() to save the new constants to nonvolatile memory. The active calibration constants stay in
effect until the instrument is power cycled or a calibration set is loaded from nonvolatile memory with the
smuX.cal.restore() function.
This function is disabled until a successful call to smuX.cal.unlock() is made.
