AC GROUND BOND TESTING (GBEZ AND GB)
These types are primarily for testing resistance values from a few microohms up to 8
Ω
at a user set AC test current
between 0.1 and 40Arms, typically for ground bond testing requirements of safety standards and also for high
current connector, cabling, or component testing.
Both GBez and GB are performed in the same manner; the difference between them is in the amount of
configuration available. The GBez type is intended for basic applications, the GB type for comprehensive testing.
The GB type can be configured to provide the same testing as the GBez type.
