Second method :
¾ Programm the transmitter in "process"
calibration mode.
¾ Make sure that the value recorded is
stabilised before adjusting it with that of
a precision calibration solution
(conductivity close to that of the
process).
Probe installation
On piping:
Entirely immerse the internal electrode in the
process (take into account the dimensions on
the following page in the event of a 90°
installation):
