Abstract

PURPOSE:To monitor plural levels efficiently with one level monitor meter, by supplying the control signal, which includes classification information of the monitor output, from a gate synchronizing circuit to gate driving circuits and switches successively. CONSTITUTION:Level monitor outputs 1a-1n are given to gate circuits 2a-2n. Level monitor outputs of the same classification of circuits 2a-2n are connected to one another by connection lines 5a, 5b..., and arbitrary connection points of lines 5a, 5b... are connected to level detection pre-units 6a, 6b... determined by classifications of level monitor outputs. Gate synchronizing circuit 9 generates the control signal consisting of the signal to select gates 2a-2n and the output display signal and supplies the control signal to gate driving circuits 4a-4n. Circuits 4a-4n generate the gate closing signal when the code from gate number setting circuits 3a-3n and the control signal agree with each other, and one output of units 6a- 6n is supplied to level meter 8 by switch 7.
