注意球探网下载:重新设定量程的压力值应该就可以了,EJA变送器的表的质量很好的,不可能调下零就坏的。

补充球探网下载:我经手的EJA还是比较多滴,给你提供几个常用的手操器菜单参数,你结合你的实际情况用吧。C21量程下限,C22量程上限,J10清零,J11通过调整该参数可使有效对应4mA,C40线性或开方,C20单位,C30阻尼。EJA 量程根据液体密度和高度等参数算好液位差压后.输入量程,就不必管了. 然后再液位零位的时候做一个零点调整,调试完毕. 量程是不会改变. 在BT200的 J10项做个ZERO ADJ 就好了. 注意观察下J11项 ZERO DEV 这是你的零点迁移量.正常后可以把它记下来,在更换通类型的变送器后,直接输入这个迁移量就可以投入使用了。
