在实时正常显示状态,使用S键能更改两个显示变量,当两个显示变量设定为相同的参数,屏幕上固定显示一种变量;当两个显示变量设定为不同的参数时,屏幕上交替显示两种变量。
方法如下:按下“S”键,当前显示变量(如:电流)发生变化,循环显示“电流、百分比、主变量”,当所需要的显示变量(如:主变量)出现在屏幕上时,松开“S”键,即实现了将显示变量“电流”改为“主变量”。
更改显示变量过程中,左下角功能码显示“30”。
例子:假设当前显示变量为“电流”,需要设置为:交替显示“主变量”和“百分比”。
步骤:修改第一个显示变量:按下“S”键,液晶循环显示“电流、百分比、主变量”,当显示“主变量”时,松开“S”键,即可。
此时,液晶交替显示“主变量”和“电流”。

在-20~20范围内设置一个与误差方向相反的相同值即可。
如偏高3,即设置-3,如偏低3即设置3。
Po: 温度回差值设置符号温度回差值:在纯位式控制中,必须有一个合适的回差值(又称开关差或不灵敏区),回差过小将导致交流接触器动作频繁而降低寿命,回差过大将导致被控制范围的环境波动变大。
在某些场合(如空调室温度控制)可利用回差值的设置使被控值在设置范围内扫描变化,避免浪费。
在一般情况下,回差值定为全量程的0.3%较为合适。
