Megger DET4TR2 Terminal Earth Tester

Rechargeable battery powered basic 4 Terminal Tester

4-terminal tester Megger's popular 4-terminal ground testing instrument family includes four basic models with different kit variants for each that include select accessories for greater testing flexibility.

Proper grounding provides many varied benefits to both people and facilities. It lessens the chance of injury due to faulty installation, reduces the likelihood of damage from lightning strikes and induced voltages, improves the performance of computer, communication and other sensitive equipment and protects against static electricity from friction. Over time, ground systems can degrade or become ineffective. Corrosion and weather influences exert mechanical strain on ground rods and cause metallic corrosion. Catastrophic events like lightning strikes or large fault currents can cause instant degradation. In addition, soil resistivity can change over time due to environmental conditions and facility expansion can create different ground system needs.

The risks from ground system deterioration include potentially deadly electrical shock situations, plant-wide equipment damage, disruption in the performance of sensitive equipment and heat build-up on a single piece of electrical equipment.
The Megger DET4TR2 can measure resistance from 0.01 ohms to 20 kΩ, a key capability for soil resistivity testing. Also, to allow accurate testing in noisy environments, the instruments are capable of rejecting noise up to 40 V peak to peak. 

All models are rated to IP54, making them truly outdoor instruments. They are designed to meet stringent safety standards and are rated CAT IV 100 V. The ground testers have been designed to be easy to use - a large selector switch makes selection of 2, 3 or 4 pole tests easy with gloved hands - and the design makes the fitting of shorting links to perform 2-pole tests a thing of the past. A large, clear, easy to read LCD and thumb sized test button also make the instruments particularly well suited to the outdoor conditions of ground testing. In addition to this ease of use feature, the instruments automatically check the connection and conditions of the P spike, C spike, and also the level of ground noise, indicating the status on the display. They also include a voltmeter to enable measurement of ground voltage.
