23. Call the niDMM Cal Adjust Gain VI.
24. Output –1 A on the calibrator.
Allow the calibrator output to settle
before proceeding
.
25. Call the niDMM Cal Adjust Gain VI.
26. Output 0 A on the calibrator.
27. Wait 5 seconds before making a measurement to allow thermal EMF
to settle.
28. Call the niDMM Cal Adjust Offset VI.
