DET4TC2 & det4tcr2 digital ground testers description megger det4 family of ground testing instr uments offers a comprehensive solution to your ground stak e and soil resistivity testing needs. the basic kit option comprises, the instr ument, test leads, stak es, batteries and calibration cer - tificate are delivered in a tough car ry case which has space to accommodate all the instrument accessories - everything you need to start testing in one kit. the DET4TC2 and det4tcr2 are designed for extended temperature range use with an ip54 rated enclosure making them genuinely outdoor instruments. the instrument provides all the functions required for ground system testing: variable frequency 2 pole, 3 pole, 4 pole, attached rod technique (art), stakeless, leakage current and ground noise voltage measurement. the instr ument is easy to use with a large rotar y selector switch and one-press test button, both of which permit operation with gloved hands. unlike some instruments, the design negates the need for a shorting link when making two pole measurements. there are no hidden functions with the instrument: clearly labelled auxiliary controls are used to select the test frequency (94 hz, 105 hz, 111 hz and 128 hz), output voltage (50 v or 25 v where local standards apply) and to switch the backlight on or off. the optional iclamp augments the traditional fall-of- potential measurement method with art (attached rod technique) which allows electrode testing without disconnection and also leakage cur rent measurements down to 1 ma. a second optional clamp, the vclamp, enables tr ue stak eless measurements to be made in situations where driving stakes is not practical. the clear , easy-to-read display provides excellent contrast and viewing angle making the instrument ideally suited to outdoor use. the display is backlit, extending the operational environment of the instrument to cable cellars and other dark locations. the instrument offers a wide measurement range of 0.01 to 200 k , ground noise voltage measurement from 1 v to 100 v and ground cur rent from 1 ma to 20 a. accurate results can be obtained in electrically noisy environments since the instrument is capable of rejecting noise voltages of 40 v peak to peak and the user can select different test frequencies to minimise the effect of interference. the DET4TC2 digital ground tester is powered from 8 aa batteries which are widely available and deliver excellent testing time. the det4tcr2 is powered from rechargeable aa cells. the battery charger is built in and the instrument is supplied with an ac/dc adaptor. for both instruments, the battery status is display using a bar-graph. the megger ground testers comply with stringent safety standards and are rated to 100 v cat iv. they also have selectable 25 v or 50 v output for compliance with iec 61557-5. n ip54 rated n 2, 3 and 4 point testing n attached rod technique (art) n stakeless measurements n user selectable test frequency n dry cell or rechargeable versions n user selectable output voltage n simple one button operation n robust carry case n backlit display n delivered with calibration certificate DET4TC2 & det4tcr2 digital ground testers
