After setting and calibrating the constant current output, be sure to reset the HHC
display to cancel with the inital display of menu B.
Important
It should be noted that if HHC is removed from the transmitter loop or the HHC power
is turned OFF when the constant current output has been set, the transmitter output
is retained at the constant current output.

Menu B : Calibration of output circuit D/A
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 milliamperemeter (ac-
curacy +- 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 "Cali-
bration" in appendix A2, and calibrate the output
circuit using the following procedure.
