Abstract
A microcomputer surveillance system is operative to monitor the output signal of a power supply to determine if an alarm limit has been reached and to center the alarm limits around an operating point of the power supply. Sensed output signals are converted to signal frequencies and transmitted optically to counters which accumulate counts indicative of the output signal. A microcomputer controller uses these counts to set alarm limits and determine if an alarm limit has been exceeded.
