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
The 19570 can be incorporated into an automated manufacturing environment
with remote start and GO/NOGO results output through the rear panel
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.
