Technical Features

This instrument is suitable for measuring contact resistance, loop resistance, and contact resistance of cables, wires, and welds on various switches and electrical appliances. It delivers accurate measurement data and stable performance, meeting the requirements of on-site high-voltage switchgear maintenance and loop resistance testing in high-voltage switchgear factories for power and power supply departments.

1. It features multiple protections, including back-EMF shock, disconnection and power failure during testing, and power overheating, reliably protecting the instrument from back-EMF shocks and providing a simultaneous audible alarm.

2. Intelligent power management technology ensures the instrument always operates at minimum power, effectively saving energy and reducing heat.

3. The instrument features flexible language switching between Chinese and English, high output voltage, and a wide measurement range.

4. The test current is derived from a high-precision, high-current constant-current power supply, eliminating the need for manual adjustment and ensuring fast and accurate testing.

5. A four-terminal wiring method effectively eliminates the influence of test lead resistance on test results.

6. A 7-inch, high-brightness color touchscreen LCD displays clearly even in strong sunlight. Full touchscreen operation allows for flexible switching between Chinese and English.

7. The instrument features a built-in perpetual calendar and power-off memory, capable of storing 1000 sets of test data for immediate access.
