The Chroma 19572 provides high current testing of ground continuity between chassis and power cord ground on a wide variety of electrical products and appliances. The unit is designed for maximum flexibility and operation convenience in mind.
The use of a high current AC test provides a better simulation of how the ground on the device would perform under actual conditions if the motor or wiring was to short to ground. This verifies that the grounds in the device can handle 30 or 40 Amps until a circuit breaker trips or fuse blows. Most European standards such as TUV, CE, VDE, UL and CSA recommend this type of testing. In contrast, the ground continuity test that is provided as part of most hipot testers just checks to make sure there is a connection.
