Railroad Testers
A railroad tester is multimeter designed specifically for use in railroad signaling and communications testing. Railroad testers measure the signal parameters of railroad coding equipment.

Railroad testers directly measure code parameters like Peak Hold, Peak Follow, Rate, and On Time in any AC or DC range. Testers may include cab filter options to allow measurements for selected cab frequencies without shutting down equipment.

Typical railroad resters are analog to display rapidly changing measurements. They report up to 500 counts per minute and are accurate within 3 percent.

TS113 Series Image
  • 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
  • Includes Black Padded Nylon Carrying Case and Test Lead Set
The Simpson TS-113 Volt-Ohm-Milliammeter 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 experience of many years of successful multimeter manufacture
2000 Series Image
  • Auto-Polarity on All DC Functions with Red NEG Indicator
  • Ohmmeter Voltage Mode Detects AC or DC Foreign Voltages
  • Multi-Turn Ohmmeter Adjust for More Accurate Setting of Ohmmeter Zero
  • Power Saving Sleep Feature Prevents Draining of the Batteries if Accidentally Left On
  • Dry Contact Requires No Adjustment to Measure Relay Contact On Time. Measure Rate Directly without Counting Power Swings. Can Detect and Hold 2 msec Momentary Closures
The 2000 Series Railroad Testers from Triplett Test Equipment and Tools are specialized Test Sets designed to perform standard maintenance tasks (using Volts, Ohms, and Amps measurements) as well as specialized tasks requiring measurements on railroad coding equipment.
The 2000 Series is compatible with older test technologies, yet is easier to use, and offers test features not found on earlier test sets. Fewer jacks, more ranges, and a logical front panel layout all contribute to the 2000 Series' ease of use. A precision multi-turn Ohms Adjust Control facilitates accurate resistance measurements. Also, the measurement of relay contact On Time has been simplified and expanded requiring no adjustments.
Code Parameter measurements have been made simpler and more accurate. No longer is it necessary to count pointer swings to measure.
On Time can be measured on live signals as well as relay contacts. Peak Levels can be determined quickly and automatically. Adjustments to the code equipment peak level can be made without constantly readjusting the Test Set.
Some models offer Cab filters, allowing measurement of the individual Cab Signal carrier frequencies, whether coded or un-coded.
  • Selectable DC Amps Polarity (Auto, Positive, Negative). Will Measure Pulse Code Transmit and Receive Currents Independently
