Measurement and Instrumentation A DC potentiometer is the best means available for the measurement of DC voltage because It is based on null balance technique. It is possible to standardize before a measurement is undertaken. None of above. The precision in measurment is independent of the type of the defector used. It is based on null balance technique.
