一般情况下，变送器零位调整只是对系统有一个零位的偏移量，但对量程的调整会对零点有1/4的影响。，某仪表厂生产的输出为（4～2）mA的变送器，若零点（4mA）已调好，在满量程时输出为2.1mA,则调整满度旋钮，调整量为（2.1-2.）1/4=.25mA，使满量程输出为（2.-.25）=19.975mA。卸压后零点输出大概为3.975mA，调整零点至4.mA，再加压至满量程调整。

不锈钢反应釜以其优良的耐腐蚀性能和较低的价格，赢得越来越多客户的喜爱和信赖；因此在搅拌与反应釜结合处的密封的选择对于密封效果、使用安全、节约成本等都显得特别重要，现对如何选择合适的密封形式做出如下建议：1.首先要明确密封选择的依据：是釜内的工作压力，第二是工作物料的性质。还有一个就是设备的工作温度。其次要明确不锈钢反应釜所用密封的类别：反应釜所用密封即通常所说的轴封有两类，是填料密封，第二是机械密封，机械密封又分为单机封（即单端面机械密封）和双机封（即双端面机械密封），单机封全套还包括水夹套，双机封则较为复杂，除水夹套（必须有循环冷却水）外，还包括配套的支架、平衡罐等。如何选择合适的密封：在常温常压，物料没有挥发性也不易燃易爆的使用条件下，要选择填料密封；在压力小于4公斤，物料的易挥发性和易燃易爆性一般的使用条件下，就要选择单机封；在工作压力超过4公斤（但要小于1公斤），物料的易挥发性和易燃易爆性很强的使用条件下，则必须选择双机封。各种密封的优缺点：填料密封价格便宜，但只适合普通的使用条件和物料；单机封价格适中，可以在大多数使用条件下通用；双机封价格贵，但在苛刻的工作条件下必须使用。
