Digital AC Ground Resistance Tester
Features Applications safety knowledge Ground impedance test aim is to ensure that when the device Product abnormal condition, the protection of ground fault current can be allowed to flow through to ensure the safety of users.Safety requirements of the standard test voltage can not exceed the maximum open circuit voltage of 12V limit, which is based on the user's security concerns, Therefore, once the test analyte occurs ; barrier, the operator can reduce the risk of electric shock. The general standard ground resistance is less than 0.1ohm, recommendations adopted by the current flow rate testing to meet The actual co-products work environment YG-7305 / YG-7305A Series Specifications
