FIELD: physics.
SUBSTANCE: method is realised by providing the measuring device with two switching devices, five switches, four multiplexers, two analogue-to-digital converters, five dividers, one multiplier, three nonvolatile memory registers, two adders and a control unit, which enables to exclude systematic additive and multiplicative errors from the operating measuring signal.
EFFECT: high accuracy of measuring devices using tensometric bridge sensors connected to an instrumentation amplifier powered by direct current, owing to elimination of systematic additive and multiplicative errors through independent measurement of these errors and removal from the overall result during normal measurement of the useful signal.
