WHY?
Ground bond test (also referred to as PE resistance test, ground continuity test) determines whether the safety ground circuit of the Device Under Test (DUT) can adequately handle fault current if the product should ever become defective. The measured resistance has to be lower than the indicated limit from the applicable international standards. Usual values are << 500mΩ.
Quanti’s ground bond is a high current continuity test. Ground continuity is important for instance in manufacturing to ensure that the products leaving to the customers are safely grounded.
Output current range 3 - 30A AC
With Quanti’s ground bond test you will test with the currents that most common standards require. User programmable output current from 3A to 30A AC provides extensive coverage for testing according to UL, IEC, EN and other requirements.
Output current resolution 0.01A
Adjustable output current and milliohm trip ranges to meet all safety specifications for ground bond test requirements.
Programmable High and low resistance limits
A resistance measurement range from 0.5mΩ to 500mΩ, in conjunction with user-programmable high and low resistance limits with Pass/Fail indication, makes this tester ideal for production testing.
4 wire measurement, constanctly accurate results
4 wire measurement ensures accurate and repeatable measurements. When measuring low values resistances, an important error source can be found in the contact resistance. In many applications, the contact resistance value can go beyond the value which has to be measured. To cancel this error source, a 4 wire measurement is used.
For instance during the day the factory ambient temperature can change, which would mean wrong resistance values with 2 wire measurements if the error is not manually and constantly offset.
