Simpson TS113 Electric, Multimeter for Railroad Servicing

The simpson volt-ohm-milli ammeter railroad Test set is a rugged, reliable instrument that has been designed for use by trained and qualified technicians associated with the railroad signaling and communications field. In construction and general principle, it follows closely the proven simpson pattern based on the experience of many years of successful Multimeter manufacture AC current transformer facilitates minimal voltage drop on time measurement at any rate in excess of 30 pulses per minute an adjustable pointer stop for observation of peak reading stabilization a Current-limiting diode prevents overload damage.
