How do I measure the grounding resistance of an ESD tester? What is the required value for ground resistance, in ohms?
A ground resistance tester can be used to measure the ground resistance of an electrostatic discharge device. First, ensure that the static discharge device is properly grounded. Then, connect one grounding electrode to the grounding point of the ESD tester, and the other grounding electrode to the ground. Start the ground resistance tester and perform the measurement according to the device’s operating instructions. The requirements for ground resistance vary depending on the application. Generally, the requirements for grounding resistance in the industrial sector are typically less than 10 ohms. However, in certain special situations, such as explosion-proof environments or precision equipment, the required grounding resistance may be even lower, at less than 1 ohm. The specific requirements need to be determined based on relevant standards, specifications, or equipment specifications. .
