The Ground Bond Tester 19570 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 to short to ground. This verifies that the grounds in the device can handle 25 or 30 Amps until a circuit breaker trips or fuse blows. Most European standards such as TUV, IEC, VDE, BABT 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 19570 offers a resistance measurement range from 0 to 510mΩ. The high and low resistance limits with pass/fail indication are also user programmable.

Remote Control
The 19570 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 19570 can be used alone or connected to Chroma 19071/19072/19073 for complete product test with the push of one button. When the 19570 has completed a continuity test, with pass indicated, it can remotely start the 19071/19072/19073 for a hipot test in sequence.

Built-In Calibration Via Software
The front panel display of an operation promoted calibration routine requires no internal adjustments.

Specifications
Model	19570
Mode	Ground Bond
Withstanding Voltage Test
Output Voltage	AC : 1~ 30 A, 0.01A step

Waveform	Sine wave
GO/NG Judgment	A no-good judgment is made when a resistance greater than the high limit value is detected. A no-good judgment is made when the output current is cutout and a no-good alarm signal is delivered. If no abnormal state is detected during the test time, a good judgment is made and a good signal is deliver.
