Track circuit measuring

Made in France

Measure and control of voltages and currents

The VS IV, digital selective voltmeter, is a selective frequency digital multimeter, movable and autonomous.

It measures and publishes on a LCD backlit screen:

  • The value of voltages or currents of UM71 track circuits as well as their modulation frequencies ;
  • The value of voltages or currents of CV SJB track circuits ;
  • The value of voltages or currents of 8700 Hz added to ITE pulses ;
  • The duration of ITE pulses.

The VS IV, digital selective voltmeter, allows track circuit measure
