CALIBRATION
This section details the PTH pressure transmitter calibration functions
using an STT04 terminal. There are three types of calibration func-
tions:
• Bench calibration.
• Rezero.
• 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 D-2 for an overview of the calibration functions.
