RCM4 Rail Current Analyser
A hand-held, easy-to-use instrument for measuring current levels and frequencies in railway track circuits. Signal analysis is performed by a mix of FFT and zero-crossing analysis algorithms. Results are displayed in bar-chart and numerical formats in rms Amps. Non-linear calibrations, out-of-limits warnings, etc are handled by internal look-up tables.
The instrument can be pre-configured for a variety of Line signalling combinations.
This instrument is no longer manufactured, but please contact us for information about repair and calibration facilities.
