The 77-Series tone tracer is a continuous or alternating tone generator that tests for continuity, polarity, voltage and resistance. It generates a distinctive audible tone detectable with headset or inductive amplifier. Tracer is compatible with ESS, Step and Crossbar. Output tone is isolated from all dc voltages. All tests may be detected, traced or located either by audio or LED indicator. Simply attach the leads to wire or cable via alligator clips or modular plug.
High-powered 77HP/6A (A) features +7 dBm output for reception up to 50,000 feet and through low-resistance circuits. Includes modular connector and two J.S. Popper 6A type (piercing) clip leads. The 77 CS case is optional. One-year warranty.
