Ⅲ． Panel indicating device:     

Ⅳ．Parameter setting：

1．  Main control set value：Under normal measurement state ,press any of ▼ or ▲ for one time，the figure flickers，this data is current main control set value，if you want to modify it，press▼or▲to modify，stop operation till ensure it., the figure flickers 8 times to save set value，then return back to normal measurement state.

2． Return difference value setting（steady-state amendment when it is time proportion controller）：Press SET for one time ，till appear，at this time press▼or▲can set return difference value，display method is kilobit LED displaythe last three digit is potential difference amendment ，it will automatically save and exit after 3s.(the meter with time proportion,，press SET for one time，till appear，then press▼or ▲can set steady-state error amendment，display method is kilobit LED display ，the last three digit is potential difference amendment，it will automatically save and exit after 3s)

3． Sensor’s error amendment：Press SET till it appear，then press▼or▲can set sensor’s error amendment，display method is kilobit LED display , the last three digit is amendment，it will automatically save and exit after 3s（when the measuring have bigger error or there is error between sensor’s position and ideal position, the measurement will occur error, the error can be eliminated  by using,the measurement value can plus and minus modify，please be careful to use this item, or it will make the measure inaccurate.）

4． Alarm control value setting（used as upper limit setting when it is upper and lower limit controller）：Press SET till it appear（no alarm or upper-limit meter without this display），At this time press▼or▲ can set alarm control value, display method is“r” and alarm value alternately display, after 3s,it will automatically save and exit.

Ⅴ．Working principle：

In schematic diagram, the signal sent by thermocouple and thermal resistance automatically cold end compensate

in the measuring bridge ,and then put it into magnifier, the signal will turn big, and at the same time revise the non-linear signal to linearity signal, enlarge the signal through linearization , one A/D switching circuit switch simulation quantity into digital signal to do digital display ,and another is transmitted to regulating network, do stated 

comparison operation ,also output needed control signal and do working state indication. 

Ⅵ．Control output：

1.ON/OFF control or potential difference control: when measurement value＜（Main control set value－return difference value）, OUT relay will always low-pass ,and high-cut, OUT indicator lighten ,and heater starts working; when the temperature goes up to main control set value, OUT relay will always low-cut, and high pass. OUT indicator goes up, and heater stops working ;When natural cooling to measurement value＜（Main control set value－return difference value    ）,the heater restart working. when =0 ,the meter carry out ON/OFF control.

2.Time proportion control：is time proportion steady–state error amendment（is identical with RESET potentiometer function of XMT*-2000 series meter’s panel）,when the temperature does not reach the proportion range of set value, OUT relay will always low-pass , and heater starts working. when the temperature reaches the proportion range,=0, the time of OUT relay’s low-pass and cut is the same. ；when＞0 ,the time of OUT relay’s low-pass is shorter, and the cut time is longer; when＜0,the time of OUT relay’s low-pass is longer ,and the cut time is shorter. When it exceed proportion range, OUT relay will always low-cut, and high pass.

3.Alarm Control :When the temperature measurement value ＞alarm set value ,alarm output ALM relay will always low-pass ,and high-cut, ALM indicator lighten.

4.Upper limit control when it is upper and lower limit meter：When the temperature measurement value＜set value  ，ALM relay will always low-pass ,and high-cut, ALM indicator lighten. So as the lower limit control.

5.Controllable silicon contact type controller, if find its load two-terminal voltage with dithering, exchange two output wire.

Ⅶ．Fault indication：

when window displays“-H-” or “-L-”，it means this channel’s sensor measurement value over loading or   the sensor has be broken，check the sensor，be sure the input between sensor and controller is the same.

Ⅷ．Connection：
