CALIBRATION
This section details the TBN480 conductivity transmitter calibration
functions using the STT04 terminal. There are three types of calibra-
tion functions:
• Process.
• Edit.
• Reset.
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 J-1 for an overview of the calibration functions
Process Calibration
This procedure applies to TBN480 Transmitters configured for either
ANALOG or DIGITAL. Any differences between the two are noted in
the Comments column.
