Switching circuit resistance tester
KDHL-100A intelligent circuit resistance tester is an important content of electrical testing, according to the “People’s Republic of China Power industry standard” DL/T845.4-2004 standard, refer to the “resistance measuring device general technical conditions Part 4: High precision circuit resistance tester” requirements.
Our company has developed KDHL-100A and KDHL-200A high precision circuit resistance tester, which can easily measure the pure resistance of the main contact resistance of the high and low voltage switch and the direct current resistance of the high and low voltage cable line.
This product overcomes the disadvantage of adjusting the current output of the traditional loop resistance measuring instrument; This product uses a large screen graphic LCD display with wide temperate backlight, instead of the traditional digital tube display, which can display Chinese characters intuitively, making the operation of the instrument more convenient and concise.
This product uses precision instrument operational amplifier and high-precision A/D converter, combined with high-performance 16-bit MCU, to ensure the test accuracy of this product; This product is also designed with real-time calendar clock, 데이터 저장고, printing and protection functions, making this product more complete and cost-effective.
