3. Zero the calibrator with the ohms-only zero (OHMS ZERO) operation. Refer to the
calibrator documentation for more information about zeroing the calibrator. This step can
be skipped if an OHMS ZERO has already been executed on the calibrator as required by
the calibrator for the specified accuracy.
4. Set the calibrator output for 4-wire compensation (COMP 4-wire).
5. Set the calibrator resistance output to 100 Ω. This is the first calibration point.
6. Set the calibrator to operate mode (OPR).
7. Open a calibration session on your module using the DAQmx Initialize External
Calibration VI. The default password is
NI.
8. Call the DAQmx Adjust 4357 Calibration VI.
9. Set the calibrator to output a resistance of 350 Ω. This is the second calibration point.
10. Call the DAQmx Adjust 4357 Calibration VI.
