ACT Meters Ltd – CALMASTER In-house Calibration Test Box

Used in conjunction with your own calibrated multimeter, CALMASTER compares accuracy between the calibrated meter and meter under test. It will verify the accuracy of resistance, AC/DC voltage and DC current readings and allow the user, if necessary, to adjust and re-calibrate the meter under test to match the calibrated meter’s specifications.

CALMASTER features variable, fine and coarse controls that enable the user to adjust resistance and voltage values of the meter under test and has pre-selected settings for current. In-house calibration certificates may be completed for future reference once the necessary adjustments have been made. With CALMASTER, re-calibration costs are now just limited to one multimeter per year, helping to reduce downtime and postage costs.

The unit is supplied with an AC mains and quality multimeter test leads for the master and meter under test.
