Introduction
After installation, conduct the initial setting on the MAINTENANCE MENU. Set and
check the following items:
Setting tags
MAINTENANCE MENU 1 <TAG>
Conduct the setting of a tag number.
Usable characters are ‘A through Z’, ‘0 through 9’, ‘/’, ‘.’, ‘’, ‘-’, and ‘space” and the
maximum number of characters is 8.
Press the [Menu] key (M) twice to display the message “MAINTENANCE MENU.”
Press the key once to display the message “1 <TAG>.” Pressing the key causes
the cursor to move.
By using the or key, select from the usable characters and input the TAG.
After inputting the TAG, press the Enter key (E). When the message “Value
Changed” appears, the setting is completed.
Setting the reference temperature
MAINTENANCE MENU 2 <Ref. Temp>
Conduct the setting of a reference temperature.
The allowable range of setting is any number from - 15 to 70°C.
Press the Menu key (M) twice to display the message “MAINTENANCE MENU.”
Press the key once to display the message “1 <TAG>.” Press the key once to
display the message “2 <Ref. Temp>.” Pressing the key causes the cursor to move.
Input by using the or key.
After inputting the reference temperature, press the Enter key (E). When the message
“Value Changed” appears, the setting is completed.
Note:
• When a set value is changed during operation, the internal flow rate calculation is
altered. If it is the case, be sure to reset the totalized value.
• Conducting the reference temperature setting causes the system to change the
maximum flow rate value (flow rate range value) to the maximum flow rate value
in the set temperature state.
• The third digit after the decimal point is rounded up.
Setting the reference pressure
MAINTENANCE MENU 3 <Ref. Pressure>
Conduct the setting of a reference pressure.
The allowable range of setting is any number from 101.325 to 1100.000 kPa.
Note that when setting the reference temperature to 0°C and reference pressure to
101.325 kPa (standard state), the unit of instantaneous flow rate, namely, “m

¡
,” that is, an Italic “ N ” is added before the unit denotation.
Press the Menu key (M) twice to display the message “MAINTENANCE MENU.”
Press the key once to display the message “1 <TAG>.” Press the key twice to
