Classic track circuit trouble shooting tool. Across the railroad industry, this product is successfully used as the common method to test track insulation of all types. It is further used to identify pockets of low ballast resistance; high resistance track wire connections in signal bonds, power bonds, impedance bonds, etc.; to test track circuit commissioning and testing shunts for proper resistance; test lightning arrestors for carbon-trace paths, etc. On both test frequencies (3.0kHz and 24.0kHz), will read resistance from Zero ohms to 10 Ohms, in 0.01 ohm steps; 11 to 50 Ohms, in 10th Ohm steps. Maximum resistance read is 150 ohms. Will indicate resistances above with symbol >150.

For identifying direction of source, frequencies and voltages of AC interference with track circuits, includes a spectrum analyzer that reads 0Hz to 20,000Hz signals above 70mV in level. Both frequencies of the signals detected and their voltages are shown in the spectrum analyzer display. Integral Voltmeter for track circuit trouble-shooting reads AC and DC voltages to 17 Volts, simultaneously. Ideal for working
with Style C (AC/DC) Track Circuits. Runs on internal, 12VDC, 1.2AH, rechargeable gel cell. Operating temperature range: -40degF/C to 140 degF/60 degC (battery dependent). Comes with 10A Probe Leads; built-in rechargeable battery; Universal Charger and zippered, padded, nylon case, with extra-large lead storage pocket.
