Auxiliary Grounding rod ： 4PCS：φ10mm×200mm
Current clamp ： 2PCS：Banana plug
Current clamp diameter ： φ50mm
Current clamp lead ： Length 2m
Measure time ：
AC current：about 2 times/sec;
Ground voltage：about 2 times/sec;
grounding resistance、soil resistivity: about 7 seconds/time
Line voltage ： Measurement below AC100V (ground voltage measurement function cannot be used to measure commercial power)
USB interface ： With USB interface, storage data can be uploaded to the computer, save and print
Communication Line ： One USB communication line, 1.5m long
Data storage ： 500 groups, "MEM" storage indicates, flashing "FULL" symbol indicates that the memory is full
Data review ： Data review function: "MR" symbol display
Overflow display ： Over-range overflow function: "OL" symbol display
Current clamp low current indication ： When measuring by the selection method or the double-clamp method, when the current signal received by the current clamp A is lower than 0.5 mA, the symbol “ ” is displayed, and at this time, the clamping direction of the current clamp A should be checked.
Interference test ： Automatic identification of interference signals, "NOISE" symbol indication when the interference voltage is higher than 5V
Auxiliary grounding test ： With auxiliary ground resistance test function, 0.00KΩ ~ 30kΩ (Rh max = 3kΩ +100R <50kΩ; Rs max = 3kΩ +100R <50kΩ)
