NOTE
• The total is accumulated from the
instantanousowrate.Therefore,thetotal
dependsontheinstantanousowrate.
• The total simulation is only applied for LCD
display and communication output and does
not affect the totalization value.
• Thesimulationsforowratearereected
to the output. Accordingly, the loop current,
LCD display, and communication output are
directly corresponded to the simulate value.
The alarm output is also available according
to the simulate value.
(3) Squawk
This feature can be used to identify the
communicating device by remotely causing LCD
to display the particular pattern as shown in the
Figure.
“SQUAWK” continues for approximately 60
seconds, then is released automatically.

9.8.2 Trim Analog Output
This function is used to adjust the analog output at 4
mA and 20 mA with the D/A trim.
(1) D/A trim
Connect a calibration digital ammeter, and then
enter the read value of the ammeter for each
outputofAXR.
• ProceduretocalluptheD/Atrim display
[Root Menu]Diagnosis/Service→Adjustment→D/A
trim
(2) Clear D/A trim
When output is reset to the original value, clear
the D/A trim.
• ProceduretocalluptheClearD/Atrim display
[Root Menu]Diagnosis/Service→Adjustment→Clear
D/A trim
CAUTION
The output adjustment function can match the
4mA and 20mA output to the reference meter
such as a voltmeter. In the output adjustment, it
is necessary to use the calibrated voltmeter and
resistance.
