The HV200UO Contact resistance instrument is a high precision, digital switch detection instrument by the IEC standards. The Instrument adopt High frequency high power constant current switching power supply technology to detect the Micro ohm contact resistance. The measurement data is accurate and correct, high stability and satisfy the requirements of Power, power supply department on-site high-voltage switch repair and high voltage switch factory contact resistance test. Output current and measurement resistance output at the same time on the 7-inch high-bright touch colour liquid crystal display, measurement results can be stored on a flash disk.
It has a variety of protective functions, such as reverse polarity, disconnection, power failure and overheat during the test, which can reliably protect the impact of reverse potential on the instrument and give synchronous sound alarm.
Intelligent power management technology, the instrument always works in the minimum power state, effectively saving energy and reducing heat.
Wide measurement range
The test current is generated by a high precision current constant current power supply, without manual adjustment, the test is fast and accurate.
Four wire connection method is adopted to effectively eliminate the influence of the test leads resistance on the test results.
Bright, touch colour LCD, full touch screen operation
Date is stored as part of the test results, can store 1000 sets of test data for reference at any time
The instrument has Bluetooth communication, RS232 communication and USB interface, used for computer communication and flash disk data storage.
