The new ground testing instrument family from Megger offers a unique solution to your ground stake testing needs. The complete kit of the instrument, test leads, stakes, batteries and calibration certificate are delivered in a tough polypropylene carry case - everything you need to start testing in one kit. The ground rod tester is rated to IP54 making it truly an outdoor instrument.
The ground tester has been designed to be easy to use - a large selector switch makes a selection of 2 poles 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 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 allow you to measure 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 the peak. The Megger digital ground tester 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 you to decide when to change the batteries before they expire. The Megger ground testers are designed to meet stringent safety standards and are rated CAT IV 100 V.
