Page 6: Overview
I. Overview The electrical integrity of earthing device is the electrical connectivity among all kinds of electrical devices that should be grounded or the electrical connectivity between ground equipment all parts and devices, it is DC resistance value; it is also known as electrical conductivity. -
Page 7: Functions
provides that the electrical conductivity should use special instruments to measure. The instrument resolution is 1mΩ; accuracy is not less than 1.0 class. Based on this standard, our company designed this high degree of automation and portable tester. It is specially used to test the electrical integrity of earthing device;... -

AC power supply, turn on power switch, the instrument enter into the starting up state. Press "test" key to begin test, the middle of the display screen shown measured resistance is the on-resistance values, its unit is mΩ. Please refer to the following table to check the test result is normal or not. -
Page 13: Notes
IX. Notes (1) Please read the manual carefully before using this tester and wire properly as recommended in this manual. (2) During testing, please make sure power supply of measured device turn off and it disconnects from other energized equipment. (3) The instrument should be firmly grounded during testing.
