Introduction

The TDR500/3 is a hand held, compact Time Domain Reflectometer for locating faults on metallic cables. It has a minimum resolution of 0.1 m/0.3 ft and a 5 km/15 kft maximum range depending on velocity factor selected and cable type.

Four output impedances are available (25, 50, 75, and 100 Ω) and a velocity factor between 0.2 and 0.99 will meet any cable test requirements

The TDR500/3 has a simple selection option which together with a 4 way control switch offers an intuitive operation for the user.

 


Measuring Functions

  • Ranges: 10m,25m,100m,250m,1000m,2500m,5000m (30ft,75ft,300ft,750ft,3000ft,7500ft,15000ft);
  • Accuracy: +/-1% of range +/- pixel at 0.67VF. (NB. The measurement accuracy is for the indicated cursor position only and is conditional on the velocity factor being correct);
  • Resolution: 1% of range;
  • Input protection: This device complies with IEC61010-1 for connection to live systems up to 150V CAT IV when used with the optional fused lead set.
  • Output pulse: 5 volts peak to peak in open circuit. Pulse widths determined by range and cable;
  • Gain: Set for each range with three user selectable steps (in manual operating mode);
  • Velocity factor: Variable from 0.2 to 0.99 in increments of 0.01;
  • TX null: Automatic.

 

 

 


Other features

An AUTO selection option ensures that the most effective parameters are selected depending on the range required, aiding rapid diagnosis of the TDR trace. A clear operator controlled cursor allows instant measurement of the distance to the fault.

A trace HOLD feature also allows the operator to hold a trace on the screen, something not seen on most other handheld TDRs. Extra high resolution together with whitelight backlight and grey scale tones give the graphical display a vibrancy, aiding the user in identifying key events on the trace.
