How often do you get your meters, clamp meters, multi meters, duspols, meggers, voltage detectors, etc tested against a known standard ?
In New Zealand for Low Voltage 240/415 Volts these are tested once a year, unless your meter gives suspect readings, or sustained damge, water etc, it will get retested sooner as long the user drops it off at our test lab.
For HV work all equipment gets tested every half year.
For electrical leads, depending upon where they are used periods are 3, 6, 12 or 60 months. as per AS/NZS 3760;2001.
I'm just doing the 6, 12 monthly tests on multimeters from the line crews who are on a refresher course at the moment.
