Short Circuit Tracer
By Distributed By MCM (MODEL 1000)
MCM Part #72-11650
A highly efficient test tool for quickly locating short circuits on PCBs.
The unit is designed as an aid for finding the most difficult fault on PCBs which is a short across two tracks that travels across a large part of the board e.g. a short across a supply line that connects to a number of ICs.
The unit emits an audible tone that reduces in frequency as the short is approached and increases in frequency as the probe is moved away.
