TBN480 CONDUCTIVITY TRANSMITTER
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
This procedure applies to TBN480 Transmitters configured for either
ANALOG or DIGITAL. Any differences between the two are noted in
the Comments column.
