III. Resetting the Controller to Original Factory Settings
J-KEM manufactures the most technically advanced temperature controller available and should give you
consistently flawless control. If you have difficulty with your controller, a good place to start to correct the
problem is by loading the original factory settings. If you still have difficulty with your controller, our
Engineering department will help you resolve the problem. The factory settings of a J-KEM controller are: 0.1
o
C
resolution, PID control with tuning parameters for a heating mantle, thermocouple type to match the thermocouple
originally installed on the controller, high temperature alarm turned on, and a thermocouple offset entered at the
time of original calibration.
