Calibrating the Main Temperature Control (OFFSET)
1. Press several times scroll to the parameter PASS. Set the PASS value to1000
2. Press and hold the key until the setup Menu page is obtained. Then, press
key to scroll to the parameter.
3. Press key several times to scroll to the parameter OFTL to calibration low
value. Send your low signal to the sensor input of the controller, then press and
release the key. If the process value (the upper display) is different from the
input signal, the user can use and to change the OFTL value (the lower
display) until the process value is equal to the value the user needs. Press and hold
the key for 5 seconds to complete the low point calibration. A similar procedure
is applied for high scale calibration.
The two points OFTL and OFTH construct a straight line. For the purpose of
accuracy, it is best to change the value same on the two points as possible.
