CdB Tester

Track circuit tester with shunt measurement

This Tester allows to carry out a series of measurements related to the particular signal of the track circuit.

Through the scrolling of a simple menu it is possible to focus the measures in:

  • Code measures
  • Axis current measurements
  • Measurements on disc relays
  • Automatic search and verification of the shunt resistance

The visualization of the measured data takes place via an alphanumeric liquid crystal display with 4 lines by 20 characters. The backlighting on command favors its use even in poor light conditions.

The presence of high-brightness LEDs on the keyboard allows you to immediately view the validation of the frequency and code measurements.

The instrument is equipped with an auto-off function after five minutes, thus preserving the state of charge of the batteries.

The Tester is supplied complete with:

  • Track Connection Accessories (Magnets)
  • Batteries and chargers
  • Disc relay contact
  • Current clamps
  • Resistive box for shunt verification
