我院土工试验室用电子天平与微机(IBM-PC/XT兼容机)联机,使含水量、流塑限称重试验实现了数据的自动采集处理。电子天平为瑞士Mettler产品,指标如下: 型号 PM-300 感量 0.01g 称重范围 300g 温度飘移 4x10~(-6)/℃误差±0.01g 数据输出 RS-232C 串行接口 110-960波特 7位ASCII码微型计算机为IBM-PC/XT兼容机。其主要性能指标是:
The geotechnical laboratory of our hospital used an electronic balance and a computer (IBM-PC/XT compatible machine) to connect online so that the water content and flow-plastic limit weighing test achieved automatic data collection and processing. The electronic balance is Swiss Mettler product with the following specifications: Model PM-300 Sensing capacity 0.01g Weighing range 300g Temperature drift 4x10~(-6)/°C error ±0.01g Data output RS-232C Serial interface 110-960 Baud 7 The bit ASCII microcomputer is an IBM-PC/XT compatible. Its main performance indicators are:
