Four-wire Electrical Test Principle
The four-wire electrical test (four-terminal resistance measurement) accurately measures low resistance without contact point interference. By separating current production and voltage measurement, contact resistance is canceled out, providing the "true resistance value."

Frequently Asked Questions
What is the advantage of the four-wire test compared to two-wire?
The four-wire test eliminates lead and contact resistance, allowing for highly accurate measurement of very low resistance (mΩ) in internal vias.
Can this machine perform both tests simultaneously?
Yes, our equipment is designed to complete both two-wire and four-wire testing at the same time to maximize efficiency.
How long does it take to install the test fixture?
The pinblock type fixture is designed for quick setup and can be installed in approximately 3 minutes without the need for cables.
What is the testing speed of the equipment?
The system can test up to 8000 points per second for 2-wire tests and 1500 nets per second for 4-wire tests.
What kind of warranty is provided?
The product comes with a standard 12-month (1 year) warranty covering parts and technical support.
What are the environmental requirements for operation?
The equipment operates best in a humidity range of 40-60% (non-condensable) and standard industrial temperature settings.
