Frequently Asked Questions - TDR2000/2P Megger
How do I set the velocity of propagation (Vp) on the TDR2000/2P?
Press the Vp button and use the arrow keys to adjust the value between 0.2 and 0.99. Refer to the cable manufacturer's specifications for the correct Vp.
What types of cables can be tested with this device?
The TDR2000/2P can test metallic cables such as twisted pair, coaxial, and power cables. It is not suitable for fiber optics.
How do I interpret the waveform on the screen?
The waveform shows reflections caused by impedance changes. A positive pulse indicates an open circuit, while a negative pulse indicates a short circuit. The distance is calculated based on the time delay and Vp setting.
What is the maximum range of the TDR2000/2P?
The maximum range is 20 km, but actual performance depends on cable type, condition, and Vp setting.
How do I change the batteries?
Turn off the device, remove the battery compartment cover on the back, and replace the 8 AA batteries (or rechargeable NiMH). Ensure correct polarity.
Is the TDR2000/2P water-resistant?
No, it is not water-resistant. Avoid exposure to moisture and rain. Use only in dry conditions.
How do I test for an open circuit?
Connect the TDR to the cable, select an appropriate range and pulse width. An open circuit will show a positive reflection at the fault location.
How do I test for a short circuit?
Connect the TDR to the cable, select appropriate settings. A short circuit will display a negative reflection on the waveform.
Can the TDR2000/2P be used on live cables?
No, the device is designed for de-energized cables only. Applying live voltage may damage the unit and cause injury.
What does the display show during operation?
The display shows the waveform, distance scale, Vp setting, and cursor position. The distance to fault is displayed numerically.
