NAHLY Micro Ohmmeter 回路电阻测试仪
产品简介
回路电阻测量是电气测试的重要内容，根据《中华人民共和国电力行业标准》DL/T845.4-2004的标准，参照《电阻测量装置通用技术条件第4部分：回路电阻测试仪》的要求。本公司研制了全新NAHLY回路电阻测试仪，可方便地进行高低压开关的主触头接触电阻值、高低压电缆线路的直流电阻值等纯阻性试品的测量。
本产品使用了*、高稳定度的直流恒流源，可提供固定直流电流输出，克服了传统回路电阻测量仪需调节电流输出的缺点；本产品采用了宽温带背光的大屏幕图形液晶显示器，而不是传统的数码管显示方式，可直观的显示汉字，使得仪器操作显得更加方便、简洁；本产品使用了精密仪用运算放大器和*A/D转换器，结合*十六位单片机，确保了该产品的测试准确度；本产品还设计了实时日历时钟、数据存储、打印以及保护等功能，使得该产品功能更加完备，性价比更高。
产品别名
回路电阻测试仪、接触电阻测试仪、开关回路电阻测试仪、接触回路电阻测试仪、接触(回路)电阻测试仪
产品特性
1.大电流：采用电源技术，能长时间连续输出大电流，克服了脉冲式电源瞬间电流的弊端，可以有效的击穿开关触头氧化膜，得到良好的测试结果。
2.抗干扰能力强：在严重干扰条件下，液晶屏一位数据能稳定在±1个字范围内，读数稳定，重复性好。
3.使用寿命长：全部采用*电阻，有效的消除环境温度对测量结果的影响，同时军品接插件的使用增强了抗振性能。
4.携带方便：体积小、重量轻。

Product introduction
Used for a variety of high voltage circuit breakers (referred to as switch) main contact contact resistance measurements, you can also test the high voltage cable lines, busbars, weld and any low resistance non-inductive electrical resistance values, etc.
Accordance with the latest standards "JJG1052-2009 loop resistance test procedures" GB50150-91 and DL/T596-1996 the relevant regulations, can be a long stable output of not less than 100A large current, the instrument can not be avoided continuous work and thus can not effectively breakdown "oxide film" of the state. Using the new power and precision measurement and control circuits combined, making the measurement data with high accuracy and good reproducibility.
Also calledname
Loop resistance tester, contact resistance tester, switch loop resistance tester, the contact loop resistance tester, touch (loop) resistance tester
The Characteristics of the products
1. large electric current: Using the latest Power technology to a long continuous output high current pulsed power to overcome the drawbacks of the instantaneous current can effectively switch contacts oxide film breakdown, get good test results.
2. anti-interference ability: In severe interference conditions, the LCD screen can be stabilized at last a data ± 1 digit range, the reading is stable and repeatable.
4. long life: all precision resistors, the effective elimination of ambient temperature on measurement results, while enhancing the use of military connectors vibration resistance.
5. Easy to carry: small size, light weight.
