Measuring system for integrated current values - has decade counter summing pulses representing current values

摘要

Electrical current values, integrated with respect to time, are measured using an analogue/digital counter, supplying an output corresponding to the current value at that point in the integration period, supplied as a potential to the inputs of a diode matrix, via a code converter. The diode matrix is connected to a storage register, supplied with clock pulses via a control unit, determining the integration period and supplying pulses corresponding to the current values to a decade counter, for of the latter.
