Chapter 6 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 the
system is in an idle or stable state with out the controller in that
calibration mode can be safely applied.

Equipment needed before calibration:
Equipment 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 ETR-Net and Smart Network
Adaptor SNA10B ( optional for automatic calibration )

Since 30 minutes are required to warm up a unit before calibration, calibrating
the unit one by one is quite inefficient. An

numerous controls is available upon request.
