PeterJames Posted November 17, 2017 Share Posted November 17, 2017 We purchased a calibration test kit and test our own meters for calibration yearly, and we by a new meter each year with a calibration certificate to test our meters against. The old meters we test for calibration and then use them as spares or replacement for failed meters. Quote Link to comment Share on other sites More sharing options...
