1.KDHL-200ASHandheld circuit resistance tester Introduction

Circuit resistance testerAlso known as a micro ohmmeter or contact resistance tester, it is an instrument specially developed by our company to measure the contact resistance of various high-voltage switches, high-voltage circuit breakers, metal welding components, metal conductor circuits, and precision micro ohmmeters.

This instrument is based on a high-speed microcontroller and combines high precisionA/D converter, digital measurement technology, anti power frequency interference technology, and excellent programmable current source technology enable the built-in large capacity rechargeable lithium battery to generate ripple free DC current, with a maximum output of 220A. The output current can be finely adjusted every 2.5A step, with up to 87 current levels, meeting the requirements of multi current level testing; At the same time, it is possible to set the time (10s, 20s, 30s, 40s, 50s, 60s) for continuous output of high current testing,And achieve the fastest testing time in the fast testing modeWithin 1 second, ensure high precision, stability, and intelligent testing even in strong interference environments.

The instrument adopts5-inch color LCD display, Chinese and English operation interface, clear and intuitive; It is also equipped with standard resistors, which can perform precision self inspection on the instrument before formal testing; The instrument has the advantages of wide range, large data storage capacity, strong anti-interference ability, simple operation, handheld, small size, and easy portability; A printer can also be optionally selected for data printing.
