If my new meter calibration says that the instrument was received by IL out of tolerance, do I need to make adjustments to my previous readings to compensate?
A. Since we have no way of knowing exactly when the changes in your readings occurred, this is not a simple answer. If there were no repairs or replacement parts, your most recent reading could be adjusted to match current readings. If your calibration factor went up, you divide your previous reading by the % of change in your calibration factor. If your calibration factor went down, you multiply previous readings by the percentage of change in you calibration factor.
