The Megger TDR2000/3 Dual Channel Power Plus Time Domain Reflectometer and Megger TDR2000/3P Dual Channel Power Plus Time Domain Reflectometer differ only in regards to their supplied test lead sets.
The Megger TDR2000/3 Dual Channel Power Plus Time Domain Reflectometer is supplied with two pairs of 2m test leads with 4mm shrouded connections to miniature crocodile clips.
The Megger TDR2000/3P Dual Channel Power Plus Time Domain Reflectometer is supplied with two pairs of 1.5m retractable sheath fused test leads.
The Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers can be used to locate faults on metallic paired cables. The velocity factor can be set to a value between 0.2 and 0.99 allowing the reflectometers to be programmed to accommodate a variety of cable test requirements.
Depending on the value of the velocity factor and the cable type, the Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers have a maximum range of 20km/ 65 kft. The Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers can be programmed to display readings in either metres or feet and have a minimum resolution of 0.1m/ 0.3 ft.
The high-resolution and the large, WVGA displays' white backlights and user-selectable colour palettes increase the ease and clarity with which key events within the trace can be identified. The Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers feature two user-selectable colour palettes, default and outdoors, as well as a custom slot allowing the user to specify the colour of up to seven screen elements. The various colour schemes ensure that the Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers can be tailored to suit the environment and/or application, as well as accommodate for eye conditions such as colour blindness.
In addition to this, the Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers feature an IP54 rated, compact, durable design ensuring that they are suitable for use in rugged indoor and outdoor environments. They are also equipped with a rechargeable Li-ion battery capable of providing the cable fault locators with up to twelve hours of power, making these instruments suitable for prolonged testing on challenging work sites.
Accessing the required settings, features, functions and modes is simple due to the intuitive and easy-to-use interface consisting of directional control buttons and soft keys. The user can override the Auto Selection function to program the Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers to his/her preferences specifying the gain and pulse as well as impedance output. The Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers are capable of issuing the following impedance outputs: 25Ω, 50Ω, 75Ω, 100Ω and 125Ω. Overriding the Auto Selection function to program the Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers manually is particularly useful when trying to identify hard-to-determine faults.
Alternatively, the Auto Selection function (unless overridden as mentioned above) will configure the Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers’ settings to ensure they are set to the most effective parameters for testing each cable. It will select the most relevant gain and pulse for each range as well as match the output impedance to the cable using an automatic impedance matching feature.
Further to this, the Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers include a number of modes and features designed to improve the ease and efficiency of locating faults along cables.
This mode automatically adjusts the gain and range ensuring that the Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers' parameters are configured to identify the cable fault using the most efficient method.
When the button for the AutoFind Mode is pressed it will move the cursor to the first event on the cable; when pressed a second time it will move the cursor to the next detected disturbance.
Dual Trace and Dual Cursor
The dual trace and dual cursor capabilities provide the user with complete control over the Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers whilst also ensuring that he/she receives an instant indication of the distance between two points. These features add to the adaptability and flexibility of the Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers.
This feature facilitates a comprehensive examination of trace conditions allowing the user to identify key events quickly, accurately and reliably.
Up to one-hundred traces can be saved to the Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers’ internal memories. Saved traces can be viewed via the instruments' displays using the recall function thereby enabling further analysis and/or comparison with the active trace.
Additionally, it is possible to download data to a PC or laptop via a USB port using the included USB lead and Megger TraceXpert Software. As well as downloading and uploading data, the Megger TraceXpert Software can be used to create reports.
The Megger TDR2000/3/3P Dual Channel Power Plus Time Domain Reflectometers are accurate, adaptable and dependable cable fault locators. They are suitable for testing a range of metallic paired cables in a variety of outdoor and indoor environments.
