MEASURING DEVICE Russian patent published in 2012 - IPC G01R17/10 

FIELD: physics.

SUBSTANCE: measuring device includes seven switches, one switching device, five multiplexers, three analogue-to-digital converters, five dividers, one multiplier, three nonvolatile memory registers, four adders and a control unit. This enables to determine systematic, additive and multiplicative errors which are then eliminated from the operating measuring signal. Switching from the mode of determining the additive and multiplicative error component values to the normal measurement mode is carried out by the control unit through a given ambient temperature change interval or a given time interval.

EFFECT: high accuracy of measuring devices.
