Unit-T Ut278A+ Capacitance Meter Test Digital Clamp Meter Resistance Data Retention Storage Function Computer Repair Circuit

The UT278A+ clamp type grounding resistance tester can measure the grounding resistance safely and quickly when measuring a grounding system with a loop. The tester does not need to disconnect the grounding lead or auxiliary electrodes, but only needs to clamp the grounding loop to be tested. The thin film alloy tongs are used to strengthen the anti-interference of the tongs, and the measuring accuracy of the ground resistance reaches 0.01Ω. Resistance limit alarm function, can set the alarm value in the range, but also has the AC current 0~20A measurement. The application of traditional methods can not be measured such as: building lightning grounding system, gas station grounding system, transmission line road tower, transformer neutral point, power plant substation, floor room grounding condition detection. Wide grounding circuit resistance measurement range (0-1200Ω), can meet most of the user's measurement requirements; 32mm big tongs, can test a variety of ground level and equal potential bus; Ac current measurement range 0-20A, and can be up to 300mA leakage current detection, can be measured without disconnection, very suitable for system fault diagnosis; User-defined HI/LO alert limits; Data retention function for obtaining stable readings in inaccessible locations; The time-saving storage function facilitates users to refer to the test data and draw tabular reports after measurement; CAT III 300V safety rating
