The Megger DET4TC2 (1000-345) is a dry-cell battery powered 4-terminal tester with selectable test frequencies, greater measurement sensitivity, and attached rod technique and stakeless measurement capability.
The DET4TC2 Tester includes a current measuring function for ART (Attached Rod Technique) testing capabilities. With this added function, on-site grounds can be tested separately without having to remove the utility connection. The DET4TC2 also provides stakeless testing capability. This method allows the operator to use the instrument like a clamp-on ground tester in applications where that method is viable, while also being able to operate as a fall of potential tester if required.
The DET4TC2 Tester is rated to IP54, making it truly an outdoor instrument. It is designed to meet stringent safety standards and is rated CAT IV 100 V. The DET4TC2 ground tester has been designed to be easy to use: a large selector switch makes selection of 2, 3 or 4 pole tests easy with gloved hands. A large, clear, easy to read LCD and thumb-sized test button also makes the instrument particularly well-suited to the outdoor conditions of ground testing. In addition to this ease of use feature, the instrument automatically checks the connection and conditions of the P spike, C spike, and also the level of ground noise, indicating the status on its display. It also includes a voltmeter to enable measurement of ground voltage.
The DET4TC2 can measure resistance from 0.01 ohms to 200,000 ohms; this measurement range is a key capability for soil resistivity testing. Also, to allow accurate testing in noisy environments, the instrument is capable of rejecting noise up to 40 V peak to peak.
The DET4TC2 is powered by eight AA batteries which are widely available and also give excellent testing time; the status of these batteries is given by a bar graph on the LCD display, allowing the operator to decide when to change the batteries before they expire.
By using the optional ICLAMP, the user can augment the traditional fall-of-potential measurement method with ART (Attached Rod Technique), which allows electrode testing without disconnection and also leakage current measurements down to 0.5 mA. A second optional clamp, the VCLAMP, enables true stakeless (clamp-on) measurements to be made in situations where driving stakes is not practical.
The DET4TC2 also features a backlit display, which extends the operational environment of the instrument to cable cellars and other dark locations. The tester also has selectable 25 V or 50 V output for compliance with IEC 61557-5. The 25 V output is required for testing in agricultural environments.
The DET4TC2 can perform bonding tests (using an AC signal) to determine that an adequate connection has been made from equipment to the grounding system, and it can also perform soil resistivity tests. This additional function can be used in prospecting, locating, and designing new grounding electrodes and systems. Furthermore, the addition of built-in current clamp capability enables fall of potential testing of attached grounds (ART) without lifting the utility connection and the addition of voltage clamp technology enables stakeless testing from the same instrument.
