Enhances capabilities with clamps for ART and stake-less .Features Megger DET4TC2 Earth Tester as primary instrument. Includes additional professional ground testing kit
The Megger DET4TC2 Digital Earth Tester combines comprehensive ground-testing capabilities with simple operation and user friendly functions. It is part of the Megger DET4 range and offers two-, three- and four-pole testing; leakage current measurement; and ground noise voltage assessment. The user has a choice of test voltages at 25V and 50V with a range of different frequencies as well as three different current outputs so the user can perform extremely comprehensive testing using only this instrument.
The Megger DET4TC2 is extremely user-friendly and can be easily operated with gloves on thanks to its large dial switch and big push buttons. There is no need to introduce a shorting link when performing two-pole testing and it is easy to switch between different voltage, current and frequency outputs. Results are easily legible on the instrument’s large, backlit screen.
The impressive measurement ranges include 0.01Ω to 200kΩ for resistance, 1V to 100V for ground noise voltage, and 1mA to 20A for ground current. The Megger DET4TC2 can still give accurate results in noisy voltage environments as it can negate interference of up to 40V peak to peak whilst the user can select a frequency to limit other interference.
The Megger DET4TC2 runs from eight AA batteries and is safety-rated as Cat IV up to 100V as well as meeting all relevant standards. Overall, it meets all ground-testing requirements and is also distinguished by its accuracy in noisy environments. The standalone product comes with a calibration certificate, a hard carry case, a stake and wire kit (15m, 10m, 10m, 3m), and right-angle terminal adapters.
The additional ICLAMP allows attached rod technique (ART) testing whilst the VCLAMP attachment allows stake-less measurement for situations where driving in stakes is impractical. For these additional clamps and a professional ground-testing set, you may wish to consider the Megger DET4TC2 Professional Earth Testing Kit.
