[a] Q: Quick performance verification test points.
[b] Select 6½ digit resolution.
[c] For 2-wire ohms, an additional 4W of error must be added.
Zero offset calibration using a multifunction calibrator is NOT recommended.
The calibrator and cabling offset can be large and unstable causing poor offset
calibration of the internal DMM.
