Fed up of sending multimeters away for re-calibration and paying someone else to perform the task?
Our ACT CALMASTER allows you to perform in-house testing and re-calibration of your own multimeters, simply and quickly, saving you time and money. CALMASTER is used in conjunction with your own calibrated multimeter. It enables you to quickly compare the accuracy between the calibrated meter and the meter under test. If the accuracy is out, CALMASTER allows you to adjust and re-calibrate the meter under test to match the calibrated meter.
