一种先进的基于微处理器和电池供电的微欧姆表，采用密封ABS外壳。5893在600μOm至60 Ohm的6个可选范围内提供0.1μOhm的分辨率电阻测量。5893具有广泛的实用功能，可满足许多国际测试标准的要求。适用于实验室和测试区域以及“现场 – 现场测试”。
微处理器技术提供许多高级功能，包括内部数字校准，6,000计数刻度长度和6个电阻范围，显示在明亮易读的LED上。使用真正的4端子，4线Kelvin / Thompson电路可消除引线电阻误差。采用平均值的正向和反向电流来消除任何热EMF误差。
自动测量和数据记录可通过RS232端口连接到PC或打印机。用于脚或手动切换的“远程操作”插座，带有“打印最后读数”控制，便于在难以接近和受限制的工作位置使用。5893的可移植性可通过可选的电池供电计算机和打印机得到增强，该计算机和打印机可放置在仪器的盖子中，是现场校准报告和证书的理想选择。
两个内部可充电电池为测量电路提供测试电流和电源。充电电路具有每个电池的独立充电指示器，快速充电至90％的容量，并自动切换至涓流充电，以延长充电时间。电池电量足以在两个10A范围内提供长达1小时的操作，在所有其他范围提供长达20小时的操作。
An advanced microprocessor based and battery powered micro-ohmmeter in a sealed ABS case. The 5893 provides 0.1 ?Ohm resolution resistance measurements in 6 selectable ranges from?600 ?Ohm to 60 Ohm. Designed with a wide range of useful features the 5893 will meet the requirements of many International Testing Standards. Ideal for laboratory and test area use as well as “on site – field tests”.
The microprocessor technology provides many advanced features which include internal digital calibration, a 6,000 count scale length and 6 resistance ranges displayed on bright easy to read LEDs.?Lead resistance errors are eliminated by the use of a true 4-terminal, 4-wire Kelvin/Thompson circuit. Forward and reverse current with averaging is employed to remove any thermal EMF errors.
Automatic measurements and data recording can be performed via the RS232 port to a PC or printer. A “Remote operation” socket for foot or hand switching with a “Print last reading” control, facilitates use in inaccessible and confined working positions. Portability of the 5893 can be enhanced with an optional battery powered computer and printer that can be housed in the lid of the instrument and is ideal for on-site calibration reports and certificates.
Two internal re-chargeable batteries provide the test current and the supply for the measurement circuitry. The charging circuit has independent charge indicators for each battery with fast charging to 90% of capacity and automatic switching to trickle charge, for prolonged charging. Battery power is sufficient to provide up to 1 hour of operation on the two 10A ranges and up to 20 hours on all other ranges.
