<p>PURPOSE:To enable the measuring and monitoring of several kinds of electric values to be measured with one measuring apparatus as desired by determining a plurality of electric values to be measured and contents of output processing through a programming depending on a voltage signal and a current signal as input source. CONSTITUTION:The voltage signal and current signal of the circuit 1 to be measured are fetched with a PT2 and CT3 and inputted into a input processing section 8. When an electric value to be measured and monitored are designated with a mode setting device 11 of a measuring mode input block 18, a program is executed corresponding to a mode of arithmetic processing blocks 20a, 20b and 20c as specified the measuring mode processing discrimination block 19 of a CPU9. The results of processing of the arithmetic processing blocks are delivered to an output processing block 21 and outputted to an electric value indicator 13, a relay contact output terminal 14, a lamp display 15 and an alarm display 16 through an output processing section 10. Thereafter, the procedure is returned to the measuring mode input block 18 and the same processing is repeated.</p> |
