Details
Contact check measurement calibration does not require range information.
Typically, calibration points one and two will be 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 will be activated immediately but are not written to nonvolatile storage. Use
smu
X
.cal.save()
to save the new constants to nonvolatile storage. The active calibration constants will stay in
effect until the instrument is power cycled or a calibration set is loaded from nonvolatile storage with the
smu
X
.cal.restore()
function.
This function will be disabled until a successful call to
smu
X
.cal.unlock()
is made.
