AC Earth Bond Test
49
Chapter 7 Specifications
Note: Upper current ranges on leakage tests are dependent on when the measurement is taken. If high values
of leakage current are present at the start and during the test the Analyser will halt the test to prevent a potential
hazardous situation arising to the end user. The upper current range for the tests below is for indication only.
