A four-terminal ground/earth resistance tester kit combining the DET4TC2 instrument with the ETK50C accessory reel set, enabling 2-, 3-, and 4-pole testing, stakeless and Attached Rod Technique (ART) modes, and soil resistivity surveys in one robust system.
A four-terminal ground/earth resistance tester kit combining the DET4TC2 instrument with the ETK50C accessory reel set, enabling 2-, 3-, and 4-pole testing, stakeless and Attached Rod Technique (ART) modes, and soil resistivity surveys in one robust system.
Designed to negate the need for a shorting link when making two-pole measurements, this ground tester also offers labeled auxiliary controls used to select the test frequency (94, 105, 111, and 128 Hz), output voltage (50 or 25 V where local standards apply), and to switch the backlight on or off.
