Megger DET4TC 4 Pole Ground Resistance Tester New
Available for rentals please call
Two more NEW Ground Testers added to the Megger Family of Ground Testers
The two new models (DET4TC and DET4TCR) as well as the DET3TC all 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). The new DET4TC and 4TCR also provides a stakeless testing technique. It 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.
The complete kit of instrument, test leads, stakes, batteries and calibration certificate are delivered in a tough polypropylene carry case everything you need to start testing in one package. (Certificate not included with analog model). Optional terminal adapters are available for acceptance of a variety of test leads.
All models are rated to IP54, making them truly outdoor instruments. They are designed to meet stringent safety standards and are rated CAT IV 100V. 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 or analog (DET3TA) display 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 connection and conditions of the P spike, C spike, and also the level of ground noise, indicating the status on the display. (The analog model allows the operator to check the condition of the spikes). The instruments also include a voltmeter to enable measurement of ground voltage. Four of the models (the DET3TD, 3TA, 3TC and 4TD) can measure resistance from 0.01 ohms to 2 k½, while the DET4TC and 4TCR can measure resistance from 0.01 ohms to 20 k½. Also, to allow accurate testing in noisy environments, the instruments are capable of rejecting noise up to 40V peak to peak.
The Megger digital and analog ground testers are 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. (On the analog model, battery status is indicated by selecting the function on the selector switch). Also, the new DET4TCR is powered from rechargeable AA cells. The battery charger is built in and the instrument is supplied with an AC/DC adapter. For all instruments, the battery status is displayed using a bar-graph. The new DET4TC and DET4TCR also have additional capabilities. By using the optional ICLAMP the user can augment the traditional fall-of-potential measurement
