The Megger DET3TC Digital Ground Tester is rated to IP54 making it truly an outdoor instrument. Designed to be easy to use – the DET3TC offers a large selector switch making selection of a 2 pole or 3 pole test easy with gloved hands – and the design makes the fitting of shorting links to perform 2 pole tests a thing of the past.
Using the optional clamp around the ground rod connection allows the testing of the rod without the need for disconnection, leaving the earthing system intact during testing (ART). A large, clear, easy to read LCD display and thumb sized test button again makes the instrument particularly suited to the outdoor conditions of ground testing.
In addition to this ease of use, the Megger DET3TC Digital Ground Tester also automatically checks the connection of the P spike and C spike, indicating the status on the display. The instrument also includes a voltmeter to allowing for the measurement of the ground voltage. The Ground Tester can measure resistance from 0.01 Ω through to 2000 Ω and earth voltages up to 100 V. To allow accurate testing in noisy environments the instrument is capable of rejecting noise of up to 40 V peak to peak.
The DET3TC is designed to meet stringent safety standards and are rated CAT IV 100 V.
