The circuit resistance tester adopts a constant current output of 200A, with an output voltage of 10V (3-5 times that of conventional instruments). It can use test wires with thinner cross-sections, reducing the labor intensity of on-site testers.

The product is mainly used for measuring the contact resistance of switch contacts and other micro ohm resistors, with fast testing speed and high accuracy.

▶ Equipped with automatic testing function, it can automatically start and stop testing; Automatically save and print test data; Continuous testing can be conducted without the need to operate instruments, greatly reducing labor intensity.

▶ The measurement range is too wide from 0-50m Ω.

▶ Equipped with voice broadcasting and prompt functions, it can report the testing status and data values of the instrument; The sound is loud and clear, improving work efficiency.

▶ The 5.6-inch large industrial grade high brightness color LCD screen displays clearly and visibly even in strong sunlight.

▶ Equipped with a built-in GPS module, it has GPS automatic timing and positioning functions, ensuring accurate clock operation.

▶ Equipped with RS232 communication interface, it can realize remote control and data upload of the instrument.

▶ Multiple current options of 200A/150A/100A make testing more flexible.

▶ Equipped with multiple protection functions such as overvoltage protection, open circuit protection, and overheating protection.

▶ Equipped with a large capacity storage, it can store 800 test records.

▶ Equipped with a USB interface, it can be connected to an external USB drive to import test data into the USB drive, making it easy to write test reports.
