Digital Ground Resistance Tester Rejects the traditional manual manual power generation method adopts advanced media and large scale integrated circuits, and uses DC / AC conversion techniques to combine the triple buttons and four-end button measurement modes with new ground resistors. .

The working principle is that the DC / AC converter in the machine changes the DC constant current, and the circuit is formed by the auxiliary ground electrode C and the measurement object E, which generates an AC voltage drop on the measuring object, and feeds the AC amplifier through assist grounding. The electrode P amplified, and then multiplied by multiplying by multiplying by a power switch to display the instrument header head, you can get three different number limits: 0 ~ 2Ω0 ~ 20Ω0 ~ 200Ω.

Nearly the resistance tester is suitable for measuring the electrical resistance of low resistance of various departments such as various devices and power postal railway communication mining; Nearly the ground resistance tester also measures soil resistivity and ground voltage.
