Note 1 : An external 250
Ω
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.

Operation
There are three modes of operation: operation, regulation and initial setting. When power is applied, controller
gets into the operation mode. Press the
key to switch to regulation mode. If the
key is pressed for
more than 3 seconds, controller will switch to the initial setting mode. Pressing the
key while in the
regulation mode or initial setting mode, forces the controller to return to the operation mode.
PV/SV: Sets the temperature set point and displays the temperature process value. Use
keys to set the
temperature set point.
Setting method: While in any function mode, press the
key to select the desired function and use the
keys to change settings. Press
key to save the changes.
The next flow chart shows how to switch for settings and internal functions:
