(3) To recalibrate, proceed as below:
a. Under the interface of figure 4-5-7-2, enter into AO calibration by pressing (As picture 4-5-7-3).
b. By using to select the sequence of 4mA calibration or 20mA calibration. After The CA value is steady, press
to finish the calibration. Once every point is calibrated, the first line shows the character [END] (as figure 4-5-7-4).
