WebOct 26, 2024 · Potentiometer calibration for an ammeter Calibration-of-Ammeter. As was already said, we will utilize a suitably steady DC supply voltage to prevent calibration mistakes that do not cause voltage variations over the duration of the experiment. The amount of current flowing across the entire circuit may be changed using a rheostat. Calibration of Voltmeter, Ammeter & Wattmeter using Potentiometer The calibration is the process of checking the accuracy of the result by comparing it with the standard value. In other words, calibration checks the correctness of the instrument by comparing it with the reference standard. See more The circuit for the calibration of the voltmeteris shown in the figure below. The circuit requires two rheostats, one for controlling the voltage and another for adjustment. The voltage ratio box is used to step-down the … See more The figure below shows the circuit for the calibration of the ammeter.
