本仪器是按电脑化设计思想设计的智能仪器,它以宏基公司“小教授”单板机的硬件为主体,精心设计具有2K字节的监控软件,它和外电路配合,具有零位自校,测量补偿,多通道监测,超差报警等十分有益的功能,並有较高的测量精度。一、主要功能和技术指标 1.每秒钟更换一次瓦斯浓度显示值;每半小时打印一次瓦斯浓度和流量值;每八小时计算並打印一次抽放的瓦斯总量;仪器还可随机打印当时的浓度和时间。 2、仪器可同时进行8通道巡回监测,通道变换时间为4.44毫秒。 3、精度;因仪器具有自动零位校正功能,减少因零飘而引起的误差,所以只要调
The instrument is designed according to the computerized design of intelligent instruments, which Acer’s “Little Professor” single-board computer hardware as the main body, carefully designed with 2K bytes of monitoring software, it and the external circuit, with zero from the school , Measurement compensation, multi-channel monitoring, ultra-poor alarm and other very useful features, and a higher measurement accuracy. First, the main function and technical indicators 1. Change the gas concentration display value once every second; every half an hour to print the gas concentration and flow rate values; calculate and print once every eight hours the total amount of gas drainage; instrument can also print at that time Concentration and time. 2, the instrument can simultaneously 8-channel tour monitoring, channel change time of 4.44 milliseconds. 3, accuracy; due to the instrument with automatic zero correction function to reduce the error caused by zero drift, so long as the tune
