ABSTRACT:
An electronic measuring device achieves an improvement in measurement accuracy while at the same time compensating for influences on the measurements, by providing for a correction factor to be stored in a correction element when the measuring device is first set up. During operation, provision is made for a test voltage to be received and compared with a reference value stored during setting. If there is a difference between the two values, a new correction factor is produced which compensates for any measurement signal effect. The measuring device is particularly suitable for electricity meters.
