Temperature Sensor Type and Temperature Range

Input Temperature Sensor Type	Register Value	LED Display	Temperature Range
0~50mV Analog Input	17		-999 ~ 9999
4~20mA Analog Input	16		-999 ~ 9999
0~20mA Analog Input	15		-999 ~ 9999
0V~10V Analog Input	14		-999 ~ 9999
0V~5V Analog Input	13		-999 ~ 9999
Platinum Resistance (Pt100)	12		-200 ~ 600oC
Platinum Resistance (JPt100)	11		-20	~ 400oC
Thermocouple TXK type	10		-200 ~ 800oC
Thermocouple U type	9		-200 ~ 500oC
Thermocouple L type	8		-200 ~ 850oC
Thermocouple B type	7		100 ~ 1800oC
Thermocouple S type	6		0 ~ 1700oC
Thermocouple R type	5		0 ~ 1700oC
Thermocouple N type	4		-200	~ 1300oC
Thermocouple E type	3		0 ~ 600oC
Thermocouple T type	2		-200 ~ 400oC
Thermocouple J type	1		-100	~ 1200oC
Thermocouple K type	0		-200	~ 1300oC

Note 1 : An external 250Ω precision resistor should be connected when the current input is selected as the input temperature sensor type..

Note 2 : (Operation mode) must be set if user wish to specify decimal point position. Except for the thermocouple B, S, R type, the decimal point positions of all the other thermocouple type input sensors can be set.

The default range of analog input is -999 ~ 9999. For example, when a 0~20mA analog input is selected as the input temperature sensor type, -999 indicates 0mA and 9999 indicates 20mA. If change the input range to 0 ~ 2000, then 0 indicates 0mA and 2000 indicates 20mA. One display scale is equal to 0.01mA.
