Data records
- The manufacturer's page for the TDR2050 was read on the date given in the value. Value: 2026-10-27.
- The manufacturer lists the TDR2050 as a two-channel cable fault locator for power applications, a time domain reflectometer. Value: time domain reflectometer.
- The TDR2050 has an AutoFind function that adjusts range and gain and moves the cursor to detected disturbances, and a FindEnd function that identifies the end of the cable.
- The TDR2050 applies distance dependent gain, which increases the gain along the returned trace to compensate for attenuation on longer cables.
- The TDR2050 is a time domain reflectometer designed for locating faults in electrical power supply cables.
- The TDR2050 has a built-in input protection filter and is designed for use on energized systems up to its rated voltage.

- The manufacturer states the operating temperature range of the TDR2050. Value: -15 °C to +50 °C (5 °F to 122 °F).
- The manufacturer states the output pulse voltage of the TDR2050 into an open circuit. Value: Up to 20 volts peak to peak into open circuit; pulse widths determined by range and cable.
- The manufacturer states the velocity factor range the TDR2050 accepts. Value: 0.2 to 0.99 in steps of 0.01.
- The manufacturer states a weight for the TDR2050. Value: 1.7 kg.
- The datasheet lists EN 60950-1 among the standards it names under safety for the TDR2050. Value: EN 60950-1.
- The datasheet lists BS EN 61326-1, light industrial, under electromagnetic compatibility for the TDR2050, with a minimum performance of B for all immunity tests. Value: BS EN 61326-1.
- The datasheet lists EN 62133 among the standards it names under safety for the TDR2050. Value: EN 62133.
- The datasheet states the TDR2050 is designed to IEC 61010-1 to protect the user when it is connected to live systems. Value: IEC 61010-1.
- The datasheet lists UN 38.3 among the standards it names under safety for the TDR2050. Value: UN 38.3.
- The catalog name of the model is written Megger TDR2050. Value: Megger TDR2050.
