Megger DET4TCR2 Earth/Ground Resistance and Soil Resistivity Tester, 4-Terminal, with Clamps and Rechargeable Battery, 0.01-200,000 Ohms Resistance Range

Rechargeable battery powered 4-terminal tester with selectable test frequencies, greater measurement sensitivity and attached rod technique and stakeless measurement capability. It can measure resistance from 0.01 ohms to 200 k ohm. 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. It include additional capabilities. By using the optional ICLAMP the user can augment the traditional fall-of-potential measurement method with ART (Attached Rod Technique), which allows electrode testing without disconnection and also leakage current measurements down to 0.5 mA. A second optional clamp, the VCLAMP, enables true stakeless (clamp-on) measurements to be made in situations where driving stakes is not practical. It also feature a backlit display, which extends the operational environment of the instrument to cable cellars and other dark locations. Finally, all units have selectable 25 V or 50 V output for compliance with IEC 61557-5. The 25 V output is required for testing in agricultural environments. Rp limit: 200k ohm (50V output voltage). Rc limit: 200k ohm (50V output voltage). Limits reduced to 100k ohm for 25V output voltage. Limits reduced to 5k ohm for 0.01 ohm resolution. Earth voltage range: 0 - 100 V. Earth voltage accuracy: 2 percent +/-2 V. 3-1/2 digit high contrast LCD, backlit. Stakeless testing capability, which allows the operator to use the instrument like a clamp-on tester in applications where the method is viable. Multiple, user selectable test frequencies allows the operator to find the most effective frequency for making the measurement. Included accessories are hard carry case, 4 Right-angle terminal adapters, leads (49 ft, 33 ft, 33 ft, 10 ft) and spikes, field calibrator, ICLAMP and VCLAMP, Earth/ground kit, C/N 6320-245 and alkaline batteries.
