Megger-DET4TD2

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. The four basic units are:

Model            Description
DET4TD2      Dry-cell battery powered basic 4-terminal tester
DET4TR2      Rechargeable battery powered basic 4-terminal tester
DET4TC2      Dry-cell battery powered 4-terminal tester with selectable test frequencies, greater measurement sensitivity and attached rod technique and stakeless measurement capability

DET4TCR2    Rechargeable battery powered 4-terminal tester with selectable test frequencies, greater measurement sensitivity and attached rod technique and stakeless measurement capability

The top-end models (DET4TC2 and DET4TCR2) include 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 (as explained further in this document). They also provide 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 basic kit includes the test leads, stakes, batteries and calibration certificate, delivered in a tough polypropylene carry case – everything you need to start testing in one package.
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.
