Calmaster is said to be a quick and accurate solution for in-house testing and re-calibration to meet BS ISO9000 requirements.
It compares accuracy between the calibrated meter and meter under test. It will verify the accuracy of resistance, voltage and current readings and allow the user, if necessary, to adjust and re-calibrate the meter under test to match the calibrated meter’s specifications.
Variable, fine and coarse controls enable the user to adjust resistance and voltage values of the meter under test.
