Product Description
20A直流电阻测试仪

20A直流电阻测试仪是一种以高速微控制器为核心,采用高频调制大功率电源、高速A/D转换器及程控电流源技术,实现了可达100A的大电流输出,达到了前所未有的测量效果及高度自动化测量功能,具有精度高,测量范围宽,数据稳定,重复性好,抗干扰能力强,保护功能完善,充放电速度快等特点的仪器,该仪器体积小、重量轻、便于携带,是变压器直流电阻测试的最新一代产品。

Functions & Features


1. High-speed 16-bit A/D converter for stable, repeatable measurements.

2、自动程控电流源技术,既可手动选择典型值输出电流也可由内部微控制器自动控制输出电流,电流源内部共设2000个电流档位,在自动状态下,由内部微控制器根据被测电阻自动控制,从而达到比较宽的测量范围和最佳的测量状态。

3、实时动态显示,响应速度快,可在测量状态直接转换分接

开关,仪器会自动提示,新的电阻值很快就会显示出来,无须重新启动。

4. Intelligent design auto-detects loose or broken test leads.

5. Complete back EMF protection with auto discharge indication.

6. Displays measurement current and time.

7. Smart power management reduces internal heating.

8、可储存250次测量数据,掉电不丢失。

9. Full Chinese menu with operation prompts, intuitive and convenient.

10、内置微型打印机,可打印测量结果和内存记录。

11、不掉电日历,时钟功能。

Notes


Due to the wide output current range, ensure the selected current does not exceed the equipment capacity before measurement. Excessive current will cause the measured resistance to gradually change due to current heating effects.

In auto current mode, the instrument uses the highest possible current, outputting various currents from 0 up to the maximum value.

The two leads of the same test clamp must be connected to the current and voltage terminals of matching colors respectively.

After each test, wait until the discharge indicator stops before removing test leads. Operators must observe safety precautions.

存储器最多可存储250次测量结果,超过250次以后最老的记录将被覆盖。
