Chroma 19572 Ground Bond Tester
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 simple front panel of the tester requires less effort to operate. The Digital display and user-friendly control allow test parameters and limits to be set easily without activating the high voltage. The instrument can be put on line rapidly. It can provide operators useful measurements with little to no training.
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 too 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.
High and Low Resistance Limits
The 19572 offers a resistance measurement range from 0.1 to 510mΩ. The high and low resistance limits with pass/fail indication are also user programmable.
The 19572 can be incorporated into an automated manufacturing environment with remote start and GO/NOGO results output through the rear panel PLC interface.
The 19070 Series Hipot Tester Compatibility
The 19572 can be used alone or connected to Chroma 19070 Series for complete product test with the push of one button. When the 19572 has completed a continuity test, with pass indicated, it can remotely start the 19070 Series for a hi-pot test in sequence.
Built-In Calibration Via Software
The front panel display of an operation promoted calibration routine requires no internal adjustments.
