MC151 Current calibrator
Powertek
If calibrator is out of limits is in some points of this test, appropriate function and range should be
recalibrated. It is not necessary to recalibrate all functions, but only this one, which does not meet
specification. See chapter Calibration mode, where recalibration procedure is described.
