Product Review

This logic probe provides convenient and precise measurement of logic circuits. It displays logic levels (high or low), pulses and voltage transients down to 25 nanoseconds. High intensity LED readouts provide instant response to the logic state. Tests all logic families (ttl, lsi, CMOS, ect), captures pulses to 25ns(20mhz), audio beeper with two sounds hi and low, memory function, colored LED's for different functions, input overload protection, logic probe is circuit powered and reverse polarity protection.
