The Morehouse Calibrator is simply inserted into a hardness tester in place of the usual metal specimen. The load is applied to the Brinell Calibrator, and the resulting deflection is read on the indicator. The error of the hardness tester load is determined by dividing the deflection of the Calibrator under load by the difference between the actual deflection and what the deflection should be for the calibrated load.
