CALIBRATION
This section details the EBTH temperature transmitter calibration
functions of the STT04 terminal. There are two types of calibration
functions:
•
Bench calibration.
•
D-to-A adjust.
NOTES:
1.
When calibrating, a field device must be connected to the
STT04 terminal.
2.
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.
Refer to Figure
for an overview of the calibration functions.
