Chapter 5 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 re-calibration unless
you have appropriate calibration equipment. If calibration data
is lost, you will need to return the unit to your supplier who may
change you a service fee to re-calibrate the unit.
Entering calibration mode will break the control loop. Make sure
that if the system is allowable to apply calibration mode.
Equipments needed for calibration:
(1) A high accuracy calibrator (Fluck 5520A Calibrator
recommended) with following function:
0-100mA millivolt source with A0.005% accuracy
0-10V voltage source with A0.005% accuracy
0-20mA current source with A0.005% accuracy
0-300 ohm resistant source with A0.005% accuracy
(2) A test chamber providing 25 BC - 50BC temperature range
(3) A switching network (SCANER 80, optional for automatic
calibration)
(4) A calibration fixture equipped with programming units
(optional for automatic calibration)
(5) A PC with calibration software BC-Net and Smart Network
Adaptor SNA10B (optional for automatic calibration)
Since each unit needs 30 minutes to warm up before calibration,
calibrating one unit each is inefficient. An automatic calibration
system for small quantity well as for unlimited quantity is available
upon request.
The calibration procedures described in the following are a step by
step manual procedures.
Apply Enter Key (press
calibration mode. see
for 8 seconds) to enter the
