The transmitter has a numerical electronic. The cell
signals are processed by a microprocessor and sent
to a digital/analog D/A converter to convert the signal
in 4-20 mA.
This menu allows to calibrate the D/A converter. It is
necessary to connect a milliamperemeter (accuracy ±
1micro A) to chack the output signal.
This menu allows too to check, with a 4-20 mA signal,
the measuring loop.
The output circuit (D/A) should be calibrated by the
following procedure when necessary.
Make transmitter connection according to “Calibration”
in Appendix A2, and calibrate the output circuit using
the following procedure.
