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 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.
b-1 4mA Adj : 4 mA adjustment
• Press the
key on the screen
c
to display the
screen for calibrating current mode 4 mA (
d
).
• Perform a calibration for 4 mA on the screen
d
with
the and keys.
• After the calibration, press the key to move to the
screen for calibration of 20 mA.
b-2 20mA Adj : 20 mA adjustment
• Press the
key on the screen
e
to display the
screen for calibrating current mode 20 mA (
f
).
• Perform a calibration of 20 mA on the screen
f
with
the and keys.
• After the calibration, press the key to move to the
constant current output screen.
b-3 FIXcur : Constant current output
• Press the
key on the screen
g
to display the
screen for performing a constant current output (
h
).
• Input a current to be output on the screen
h
with the
and keys.

value and the screen
j
appears.
Press the or key to cancel the input and return
to the screen
g
.
• Press the
or key on the screen
j
. FIX blinks
and you can reset the constant current output value
(
k
). Input a set value with the and keys, press
the key to return to the screen
j
, and output the
reset current.
• Select EXITFIX on the screen
k
and press the key
to stop the constant current output and move to the
item name selection screen.
Note)
To exit of the constant current, please continue to scroll the
value until EXITFIX.
If nothing is input for three minutes in the status of the con-
stant current output, the screen returns to the normal mode

the lighted FIX. Select the setting mode again. Select “FIX
cur” on the display
k
in the items of “6-3. FIX cur” and
press the key to terminate the constant current output.
