Simple question - how often should multimeters be calibrated? Annually? 3 year?

    Depends if your buying Chinese stuff which don't give you correct readings

    most stuff is re branded Chinese stuff,

    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.
