II. 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 into the setpoint controller (i.e., the meter on the left). 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.
This reset procedure should only be applied to the setpoint controller (i.e., the meter on the left). None of
the parameters of the limit controller should be changed.
1. Press and hold in both the ▼ and ▲ keys on the front of the temperature meter until the word “tunE” appears in the display, then release
both keys.
2. Press the ▼ key until “LEVL” appears in the display. Next, hold in the ‘*’ key, then while holding in the ‘*’ key press the ▲ key until “3”
appears in the display. Let go of all the keys.
3. Press the ▲ key until “rSEt” appears in the display. Next, hold in the ‘*’ key, then while holding in the ‘*’ key press the ▲ key until the
word “All” appears in the display. Let go of all the keys.
4. Press and hold in both the ▼ and ▲ keys until the word “inPt” appears in the display, then release both keys.
The value that needs to be entered depends of the type of thermocouple receptacle your controller was shipped with.
Determine the thermocouple type below.
Color of thermocouple receptacle (Fig 1; # 7) Value to enter:
Blue (type T) “tc ”
Yellow (type K) “tc ”
Black (type J) “tc ”
First hold in the ‘*’ key, then while holding in the ‘*’ key press the ▲ key until the value from the table above appears in the display. Let
go of all the keys. NOTE: Many of the patterns for this parameter look similar, be careful to select the exact pattern shown above.
5. Press the ▲ key once and “unit” will appear in the display. Next, hold in the ‘*’ key, then while holding in the ‘*’ key press the ▲ key
until the value “o C” appears in the display,. Let go of all the keys.
6. Press the ▲ key once and the word “SP1.d” appears in the display. Next, hold in the ‘*’ key, then while holding in the ‘*’ key press the
▲
key until the value “SSd” appears in the display. Let go of all the keys.
7. Press in both the ▼ and ▲ keys until the temperature appears in the display (the word “PArk” also appears), then release both keys.
8. Press and hold in both the ▼ and ▲ keys on the front of the temperature meter until the word “tunE” appears in the display, then release
both keys.
9. Press the ▲ key once and the word “bAnd” will appear in the display. Next, hold in the ‘*’ key, then while holding in the ‘*’ key press
the ▲ key until the value “10” appears in the display. Let go of all the keys.

13. Press the ▲ key once and the word “CyC.t” will appear in the display. Next, hold in the ‘*’ key, then while holding in the ‘*’ key press
the ▲ key until the value “30” appears in the display. Let go of all the keys.
14. Press the ▲ key until the word “SPrn” appears in the display. Next, hold in the ‘*’ key, then while holding in the ‘*’ key press the ▼ or
▲
key until the word “OFF” is displayed. Let go of all the keys.
