METRAVI CET-04 CLAMP ON GROUND RESISTANCE TESTER MODEL NO. CET-04 4 Digits LCD, 28mm Clamp Jaw Dia, Data Hold, Open Clamp Jaw Indication, Range 0.010 to 1000 Ohms. Maximum Resolution 0.001 Ohms. With Leakage Current Measurement up to 20A. Description Widely applied in ground resistance measurement, loop resistance measurement in fields such as electric power, telecommunications, meteorology, oil field, architecture and industrial electrical equipment. Can measure the leakage current of ground wire. Clamp Earth Resistance Tester measures the integrated value of ground resistance and resistance lead. When measuring ground system with loop, there is no need to disconnect the ground wire without auxiliary electrode, which means safer and faster. Clamp Earth Resistance Tester can measure the ground fault which can not be measured by traditional method, can apply in the occasion where traditional methods are unworkable. The latest updated series Clamp Earth Resistance Testers have better performance: Boot up instantly, avoid boot up errors; More reliable battery cover, convenient to change battery; Wider range, larger memory; Optional RS232 interface, available to transfer data to PC and generate report files, easy to analyse or backup data. Clamp Jaw: 32mm Display: 4 digit Backlit LCD Resistance Range: 0.01 to 1200 Ohms Resolution: 0.01 Ohms Current range:0.00-20.00A Resolution: 0.05mA Storage of Measured Data: 99 Data Setting of Resistance Alarm Critical Value: 1 – 199 Ohms Setting Range of Current Alarm Critical Value:1-499mA Data Hold, Auto Power Off
