Abstract
PURPOSE: To prevent a max./min. value pointer from working excessively by providing an automatic regulating circuit on an input circuit to a meter, thereby controlling automatically a rise of input quantity to measure.
CONSTITUTION: An automatic regulating circuit consisting of a nonlinear resistance circuit 10 and a condenser 20 is provided on an input circuit to a meter M. The automatic regulating circuit works to suppress a rise of input current to a moving coil of the meter M in proportion with the rise of voltage wave form to measure getting high.
