ABSTRACT The noisy amplified signal from a photoelectric device is passed through an electronic low-pass filter before having its direct current component read on a meter. The cut-off frequency of the low-pass filter is adjusted in known manner by rotation of a control knob, so as to suitably match the cut-off frequency to the noisiness of the signal with a view towards speeding up the stabilization of the meter reading. To overcome the slugish- ness of the system, the same control knob is briefly pushed, thereby overriding the low pass control. The method of using the system to speed up meter reading is described. - 1 -
