This section details the TB82 transmitter calibration functions using
an STT04 terminal.
NOTE: When calibrating, a field device must be connected to the
STT04 terminal.
Refer to Figure N-2 for an overview of the calibration functions.

This procedure describes how to perform a one-point calibration. This
procedure is generalized for all TB82 devices (pH, ORP, pION and
CONC). Differences between devices are noted in the
column of the table.
