M5 为保持参数。定义为输出值变化 5％时，控制对象基本稳定后测量值与变化前测量值的差 值。同一系统的 M5 参数一般会随测量值有所变化，所以应取工作点附近为准。M5 参数值主要决 定调节算法中积分作用，和 PID 调节的积分时间类似。M5 值越小，系统积分作用越强。M5 值越 大，积分作用越弱。

富士PXW9温度控制仪操作指南名称功能输出1指示灯灯亮为输出1为ON输出2指示灯灯亮为输出2为ONPV(测量值) 指示测量值报警灯检测出报警时灯亮，报警输出为ONSV(设定值) 指示设定值，在设定参数时，指示参数数据SEL键参数选择键选择SV/PV显示，选择参数，选择参数和参数值显示等增/减键改变SV值，顺序选择参数。

在参数设定时，增/减参数数值SV指示灯显示设定值(SV)时，此灯亮注意：当无操作状态持续30秒时，将返回接通电源时的状态，新设定的数据可能没储存。

因此应按SEL键返回初始状态。

一. 基本操作:1.1控制温度SV的设置：按∧键提高设定温度，按∨键降低设定温度（在锁定状态下不能修改）。

1.2第一组参数设定：在PV/SV显示模式下按 SEL键3秒后进入第一组参数设定模式，每按一次SEL键参数将依次显示。

按∧键或∨键可改变设定参数的值。

1.3第二组参数设定在PV/SV显示模式下按SEL键7秒进入第二组参数设定模式，按∧键或∨键可改变设定参数的项目，选定要修改的项目后按SEL键进入参数设定窗口，按∧键或∨键设定参数值，设定完成后按SEL键回到参数项目设置模式，再按∧键或∨键可选择其它参数继续设置。

1.4第三组参数设定在PV/SV显示模式下按SEL键9秒进入第三组参数设定模式，按∧键或∨键可改变设定参数的项目，选定要修改的项目后按SEL键进入参数设定窗口，按∧键或∨键设定参数值。

设定完成后按SEL键回到参数项目设置模式，再按∧键或∨键可选择其它参数继续设置。

温湿度控制器一、产品概述温湿度控制器，主要应用于需要对被测环境进行自动温湿度调节的场合，用户可通过按键分别调整温湿度的上、下限值来控制加热或排风实现自动控制，显示方式为数码管显示。

二、基本功能：2.1 温度测量范围：-25℃～+80℃±1℃；2.2 湿度测量范围：相对湿度RH: 0%～99% 精度±3%RH；2.3 控制方式：温度采用上、下限和回差控制，湿度采用上、下限控制，所有参数均可设置；2.4 输出控制类型：两组继电器触点，分别为加热和排风，每路最大负载AC250V /3A，均为有源输出。

三、技术指标：3.1电源：AC 220V±20%3.2 工作环境：温度:-25℃～+55℃，相对湿度：<95%RH3.3控制设定范围：温度：0℃～80℃，相对湿度：50%RH～99%RH3.4 本机功耗：<3W3.5自检功能：若数码管显示“–––”，则为检测到传感器故障；若加热或排风运行过程中相应指示灯熄灭，则检测到加热或排风故障。

四、工作原理：4.1 温度控制：当被测环境温度低于设定温度下限时，本仪器启动电加热设备开始加温，此时加热指示灯亮，温度升至比下限温度设定值高回差值时，即：W测≥W下限+回差，停止加温。

当被测环境温度高于设定温度上限时，本仪器启动降温设备（如风机或空调）开始降温，此时排风指示灯亮，温度降至比上限温度设定值低回差值时，即：W测≤W上限－回差，停止降温。

4.2 湿度控制：当被测环境湿度超过设定湿度上限时。

如果当前温度较高，即：W测≥W下限＋(W上限－W下限)×3÷4，采用降温（或排风，视具体地区采用不同设备）抽湿，此时排风指示灯亮；抽湿过程中，如果温度低于下限温度+2度后，自动转为加热降湿；当降湿过程中温度高于上限温度-2度后，自动转为降温抽湿，直至湿度低于设定下限值为止。

当被测环境湿度超过设定湿度上限时。

如果当前温度较低，即：W测＜W下限＋(W上限－W下限)×3÷4，采用加热降湿，此时加热指示灯亮，降湿过程中，如果温度高于上限温度-2度后，自动转为降温抽湿；当温度低于下限温度+2度后，自动转为加热降湿，直至湿度低于设定下限值为止。
