Abstract

PURPOSE: To prevent drift of output signal, omitting A/D converter by picking-up input signal to the processor as time width signal, by refreshing the hold circuit for output with data memory in the processor.
CONSTITUTION: With automatic control, a change-over switch SW is connected to the side A, output of processor 5 is output through D/A converter 6 and hold circuit 7 as control output es. In this case, measuring signal em and setting signal es are obtained as time width signal through a comparator 32, 33 which the lamp signal obtained with the block 4 is applied at one input terminal respectively, its time width is converted to the digital value. With manual control, output of manual regulator 8 is applied to the hold circuit, its output is set to the data memoryof the processor 5 through the comparator 31, thus the hold circuit is refreshed.
