The transmitter has a numerical electronic. The
cell signals are processed by a microprocessor
and sent to a digital/analog D/A converter to con-
vert the signal in 4-20 mA.
This menu allows to calibrate the D/A converter. It
is necessary to connect a milliampere meter (ac-
- 1 micro A) to check 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 "Cali-
bration" in appendix A2, and calibrate the output
circuit using the following procedure.

The transmitter will calculate automatically the
gap between the theoretical and the measured
values. It will rectify in the D/A converter.
