VS IV selective voltmeter

Measurement and control of voltages and currents

The VS IV, Selective Digital Voltmeter, is a digital multimeter with selective frequency, portable and autonomous.

It measures and displays on a backlit LCD screen:

• The value of the voltages or currents of the UM71 type track circuits as well as their modulation frequencies
• The value of voltages or currents of CV SJB type track circuits
• The value of the voltages or currents of the 8700 Hz superimposed on the ITE pulses
• The period of the ITE pulses
