The Megger DET4TCR2 boasts extensive measurement ranges for resistance (0.01Ω to 200kΩ), current (1mA to 20A), and ground voltage (1 to 100V). The gadget can eliminate background voltage noise up to 40V peak to peak, which helps accuracy. The various frequency choices also aid in this respect. The Megger DET4TCR2 is equipped with an AC/DC adaptor as standard, and its AA batteries are fully rechargeable. There is a bar graph that shows the battery level. The user can be confident that this earth tester will work as intended because it meets all safety requirements, including Cat VI to 100V under IEC61010-1 and an IP54-standard weatherproof enclosure. The Megger DET4TCR2 Rechargeable Earth Tester is a member of the DET4 series and offers sophisticated ground-testing features together with an intuitive user interface. It can measure leakage current and ground noise voltage in addition to conducting two-, three-, and four-pole ground tests. With frequencies of 94Hz, 105Hz, 111Hz, or 128Hz, the voltage output can be adjusted to either 25V or 50V. The Megger DET4CR2 is quite adaptable because it has three current output options: 4.5mA, 0.45mA, or 0.045mA. Easy to use functionality is yet another useful aspect of the Megger DET4TCR2. Its large dial navigator and test button, the size of a thumb, make it easy to use even when wearing gloves. Two-pole testing eliminates the need for a shorting link and makes it incredibly easy to transition between various test modes thanks to its clever design. For earth testing in outdoor environments, the 3.5" illuminated LCD screen clearly displays results, and the entire equipment performs flawlessly. To optimise your purchase, you might want to look into the Megger DET4TCR2 Professional Earth Testing Kit, which includes the same clamps as well as extra ground-testing accessories, or the Megger DET4TCR2 Rechargeable Earth Tester Kit with Clamps, which has extra clamps that enable ART and stake-less testing.
