Do not proceed through this section unless there is a definite need to
re-calibrate the controller. Otherwise, all previous calibration data will be
lost. Do not attempt recalibration unless you have appropriate calibration
equipment. If calibration data is lost, you will need to return the controller
to your supplier who may charge you a service fee to re-calibrate the
controller.

Entering calibration mode will break the control loop. Make sure that if
the system is allowable to apply calibration mode.

Equipments needed before calibration:Equipments needed before calibration:
(1) A high accuracy calibrator ( Fluke 5520A Calibrator recommended )
with following functions:
0 - 100 mV millivolt source with 0.005 % accuracy
0 - 10 V voltage source with 0.005 % accuracy
0 - 20 mA current source with 0.005 % accuracy
0 - 300 ohm resistant source with 0.005 % accuracy
(2) A test chamber providing 25 C - 50 C temperature range
(3) A switching network ( SW6400, optional for automatic calibration )
(4) A calibration fixture equipped with programming units ( optional for
automatic calibration )
(5) A PC installed with calibration software BC-Net and Smart Network
Adaptor SNA10B ( optional for automatic calibration )

Since it needs 30 minutes to warm up an unit before calibration, calibrating the
unit one by one is quite inefficient. An for small
