CALIBRATION
This section details the calibration functions of the STT03E terminal while
interfacing a BCN transmitter. There are three types of calibration functions:
•
Bench calibration.
•
Rezero.
•
D-to-A adjust.
When calibrating, a field device must be connected to the STT03E terminal.
When using an IMFBS01 module (field bus), up to fifteen transmitters can
be connected to the bus. Select the field device by using
.
NOTE:
To change calibration or configuration parameters of a field device
that is connected to an IMFBS01 module, the transmitter must be taken
off-line. This is done at the INFI 90 OPEN console.
After selecting a field device the
READY
screen appears. All calibration
functions can be performed on the selected device. Refer to Figure
for
an overview of the calibration functions.
