401 Impedance Bond Integrity Tester

 Easily portable Tester used to test conventional impedance bonds (not Wee-Z type impedance bonds). Allows user to determine the impedance of a bond at selectable test frequencies of 60 Hz and 156 Hz. Indicator flashes at 1-2 ohms. Meter reading covers a non-inductive resistance range of zero to 100 ohms. Operates on one 9V batter (included). Push-button controlled LED's light meter for 15 seconds at a time for nighttime use. Comes complete with zippered, padded case and leads equipped with BU-11 batter clips for gripping impedance bond terminal lugs.

Model 400 Train Stop Inductor Tester

 Tester is designed to identify the impedance range of the inductor choke coil with a Laminated Test Bar accessory simulating the on-train receiver. A reading above or below the acceptable range indicates a bad inductor. This test simulates a live, operational environment which is the most complete form of test.

To help insure that the Tester internal batter is not depleted unnecessarily, the power switch is a dependent push-button. The power switch must be depressed to conduct a test. At all other times the Tester is turned off. The Model 400 Train Stop Inductor Tester comes in a rugged, fiberglass-reinforced, poly-vinyl case complete with leads, charger for the build-in, lead-acid gel cell, and removable, padded shoulder harness.

577 Cab Signal Code Analyzer
Handy tool for setting up and maintaining coded track circuits in cab signal territory. Connects directy to the track for track measurement, or for convenience, has test leads with clips to connect to track wire terminals in the bungalow or case.

Nominal internal hard shunt helps the 577 Cab Signal Code Analyzer deliver accurate information on the capacity of the track circuit to maintain proper current levels. Display provides usable information as the tests are being made. "No Code" LED indicates (on) when no code or no track circuit is present.

Input filtering is used to roll off the higher frequency signals on the track, either above 400Hz or above 200Hz depending on the filter option ordered. These filters will limit the influence of adjacent track circuits if those frequencies are sufficiently higher than the filter frequency. Rugged construction. Unit is housed in a weather resistant, gasketed 10 in by 10 in. by 5 in. (nominal) case. Heavy duty, low resistance, twist lock connectors couple track leads to the Analyzer.

  1. Rugged, Compact
  2. Easy-To-Use
  3. Provides code rate indicators (LED's) and code rate readout
  4. Displays code rate percent on and off
  5. Displays track circuit frequency
  6. Low pass filter options remove interference above a select frequency
  7. Requires track current to be 1 AMP to operate, measures current to 20 AMPS
  8. Connection Mode re direct track connection, track wire terms in case, and no load bridge
  9. Heavy-duty, 10 ft, #6 awg welding cable track leads, base or head clamps
