CALIBRATION

This section details the AS800 pressure transmitter calibration func-
tions using an STT04 terminal. There are four types of calibration
functions:

Input A/D

•
D-to-A adjust (Analog Mode only)
•
Zero Trim
•
Temperature
•
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 P-2 for an overview of the calibration functions.
