Features

1.Without enterring the menu,the self-tuning funtion will be actived by keeping pressing the "AT" for a while.
2.Self-tuning AT is fast,stable and excellent,and with high precision. 3.Multi kinds of standard signal,thermocouple TC,thermal resiatance RTD,analog quantity ***0mA,**5VDC and so on,are free to ,so as the measuring range. The circuit of wide-width switching power,AC*****0V,is widely suitable to many kinds of voltage,good at resisting the interference of harmonic,and in good stablity.In one word, it can meet all the requirements from different working environments.
4.The deviation can be corrected,and the cold side of sense-transfering line can test the temperature alone.The amplifier of the cold side can return to zero by itself,the precision is ±2%FS.
5.Main outputs: "R"*-Relay controlling AC contactor 
                        "S"*-Impulse zero triggering SSR 
                         "I"*-Current output ***0 mA,impulse triggering Voltage-                               regulator            
                         "U"*-Voltage output **5 VDC,impulse triggering Voltage-                                 regulator
6.Two kinds of independent  output for alarming,4 kinds of alarming ways can be  customed

Technical Parameters
1.The precision of setting:±0.5% FS±1 during the whole measuring range. 2.The precision of measuring:±0.2% FS±1. 3.The frequency of sampling:2 times/sec. 4.The s(standard signals,free to combine) :K,K1,J,E,E1,S,N,T,B,R,Wer,Pt**0,Cu*0,**5V,**5V,***0mA,***0mA and ***0mA.  5.The ways of controlling temperature: (1) Intelligent setting:factory Initial setting P,I,D.      But when the temperature is fluctuating around the critical point,the value of P,I and D can be adjusted. (2)Time proportional controlling:modify I=0,D=0,P =*0.
(3)Reach-stop controlling:modify P=0,I=**0,D=*0;
(4)Upper-lower limit controlling:modify P=0,and set "HY"(the *6th item in the third level of menu) as what you need to control the section,and set "Ft"(the *1th item in the third level of menu) set as "0". 6.Output controlling:
(1)The analog quantity:"I"*-Impulse current output ***0 mA.                  "U"-Voltage output **5 VDC. 
(2)The swich quantity:"S"*-Impulse voltage *2VDC.                                     "R"*-Relay controlling AC contactor. 7.Relay contact loading:**0VAC/3A (not conductable), **0VAC/1A (conductable,CosΦ=0.4). 8.Impulse voltage loading:*2VDC, max=*0mA(impulse SSR,with protection of short circuit). 9.Analog voltage and current loading:(standard)**5VDC,***0mA,loading resitance Max=**0Ω. *0.Alarm funtion:4 kinds of alarm of deviation value for upper and lower limit,the absolute value of alarming funtion  for upper and lower limit is free to combine. *1.Alarming output loadingL:relay contact **0VAC/3A (not conductable), **0VAC/1A (conductable,CosΦ=0.4). *2.The waste of voltage:*****0VAC,****0Hz,≤5W. *3.Insulating resistance:≥*0MΩ(testing condition is **0VDC),(the main output is current or non-contacted  voltage,the resitance of its  (or output)terminaller and CT terminaller don't need to be tested. *4.The temperature and humidity of the working environment: temperature:**0~**5°c,humidity:****5% RH.
