The shield digital electrical measuring device Shch20.3 is designed to measure current or voltage in DC circuits for operation as part of the technical means of nuclear power plants, as well as in other industries. The device can be used in a set with primary converters for measurement of non-electrical quantities, if the ranges of the output electrical signal of primary converters correspond to the ranges of the input signal of the devices.
The device provides the following possibilities: selection of the input signal measuring range, change of the reading range and unit name; setting of the discrete-analog DUT colour signalling zones, which are formed by the number of single indicators of each colour set at the order; parameter programming by means of the built-in button. The device is made in a metal case of panel mounting.
