Chapter 8 Manual Calibration
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 - 10 V voltage source with
0 - 20 mA current source with
0 - 300 ohm resistant source with
(2) A test chamber providing 25 C - 50 C temperature range
(3) A switching network ( SWU16K, 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 )
The calibration procedures described in the following section are a
step by step manual procedures. manual procedures.
Since it needs 30 minutes to warm up an unit before calibration,
calibrating the unit one by one is quite inefficient. An
