Self-diagnosis
Use for displaying the measured temperature
in the transmitter and the alarm information.
When pressing <1> on display 2 , the tem-
perature in the amplifier (AMP TEMP) is
displayed. When pressing <2>, result of self-
diagnosis about transmitter (ALM CHECK) is
displayed.
Result of diagnosis
When the temperature in the ampli
fi
er is normal:
When temperature alarm is detected:
When no error has occurred:
When an error has occurred:
For contents of error, refer to "Contents of message" on
the next page.
Indication of measured data
The measured value can be indicated.
For more information about operating proce-
dure, refer to the instruction manual of FXW.
