The Megger DET4TC2 + ETK50C (1012-521) 4-Terminal Ground Resistance Tester and 50m Cable Reel Earth Test Kit offers both a testing instrument and complete set of accessories for a full ground resistance and soil resistivity testing operation.

The Megger DET4TC2 4-Terminal Ground Resistance Tester includes a current measuring function for Attached Rod Technique (ART) testing capabilities. With this added function, on-site grounds can be tested separately without having to remove the utility connection. Stakeless testing capability is also provided by the unit in which this method allows the operator to use the instrument like a clamp-on ground tester in applications where the method is viable. If required, the unit can be operated as a fall-of-potential tester.

The IP54 rating of the DET4TC2 makes this an outdoor instrument in which it is also rated to CAT IV 100V for stringent safety standards. Easy to use, the tester can be operated even while wearing gloves in order to make the selection of 2, 3, or 4-pole testing via the large selector switch. The large, clear, and easy-to-read LCD and thumb-sized test button enable easy outdoor testing. The tester automatically checks the connection and conditions of the P spike, C spike, and also the level of ground noise. The included voltmeter enables measurement of ground voltage.

The Megger DET4TC2 offers additional capabilities in which, with the usage of accessories within the ETK50C kit, can offer heightened testing abilities. By using the ICLAMP Current Clamp, the user can augment the traditional fall-of-potential measurement method with Attached Rod Technique (ART). ART allows for electrode testing without disconnection and also leakage current measurements down to 0.5 milliamps. The VCLAMP Voltage Clamp enables true stakeless (clamp-on) measurements to be made in situations where driving stakes is not practical.

The backlit display of the DET4TC2 4-Terminal Ground Resistance Tester extends the operational environment of the instrument to cable cellars and other dark locations. This unit features a selectable 25 or 50 voltage output for compliance with IEC 61557-5. The 25 voltage output is required for testing within agricultural environments.

The Megger ETK50C 50m Cable Reel Earth Test Kit is an accessory kit designed for complete earth electrode testing and soil resistivity surveys. Housed in a holdall, the kit is well protected and easy to transport. The test leads are fitted and retained on reels with a smooth action. Operation is simple in which the user can run out the test lead from the instrument to the test point, clip the end directly into the spike, and perform the test. Once the test is complete, the test leads can be unclipped and winded back in.

The ETK50C kit is supplied with a tape measure to ensure accurate placement of test spikes or pins. The reels can be daisy-chained together to provide longer lengths in manageable chunks. This daisy-chaining ability makes the reels lighter and easier to carry for the user.
