Prerequisites for Construction of a Device for Measurements of Electric Field Strength with Determination of the Measurement Error

A new solution is proposed for construction of a device for measurement of electric field strength with determination of the measurement error. The device is based on a dual-type sensor, which makes it possible to reduce the error, expand the spatial range of measurement, and instrumentally determine the measurement error from two simultaneous single-point measurements of the field strength obtained with errors of different signs. The ability of the device to instrumentally determine the measurement error is considered for the first time.
