NOTE: Commands used in the following calibration procedure can be
executed either by using the CAN tool, the HART SmartView, or
Engauge.
Calibrate the analog output of the HCI-HAO as follows:
☛
Connect loop resistor at connector CN2
☛
Power up HCI-HAO board
☛
Give command [Enter Calibration Mode]
☛
Give command [Calibrate Analog Output at 4mA]
☛
Measure actual output current through the loop resistor, using a
current meter
☛
Enter this value in the
☛
Give command [Calibrate Analog Output at 18mA]
☛
Measure actual output current through the loop resistor, using a
current meter
☛
Enter this value in the
☛
[Exit Calibration
Give command
These calibration data are used to calculate the analog output current
for the Primary Value (PV).
Until calibration has been carried out, the Health status of the PV and
the analog output function will be:
Status <BAD>
<STATUS_CATEGORY_BAD_GENERAL_CALIBRATION_FAIL>
Status Category
<CALIBRATION_SET_POINTS_NOT_CALIBRATED>
