Product description Earth ground resistance tester is a high-precision testing instrument used in various fields such as substations to test grounding resistance and related parameters.The instrument is of an integrated structure, with a built-in frequency conversion power supply module, and the output power supply is continuously variable in frequency. The frequency can be changed to 45Hz or 55Hz, the high-speed processor core is built in, and the high-end digital filtering technology is adopted, thus effectively avoiding the interference of power frequency electric field to the test and fundamentally solving the difficult problem of accurate measurement under strong electric field interference. Technical index 1 Conditions of use 1 540 RH 80% 2 Anti-interference principle Frequency conversion method 3 Electric source AC 220V 10% allowed generator 4 Measure output current 1A 5A Adjustable 5 Measure output voltage 0V 100V 6 Test power frequency 45, 50, 55, 60, 65HZ single frequency 45 55, 55 65 47.5 52.5HZ Automatic Dual Frequency 7 Output rating 500W 8 Distinguishing rate Grounding impedance 0.0001 Impedance angle 0.0001 9 Precision Grounding impedance 1% reading 0.002 Impedance angle 1% reading 0.02 10 Resistance measurement range 0.001 5 11 Exterior dimensions 370 295 W 225 H 12 Memory size 100 groups support U disk data storage 13 Weight Main engine 13 Kg, ground pile 7 Kg
