(3) Select Backup mode (temperature value backup when the analog input is outside the
range) from the following options.
If you select Disable, the analog input is converted as-is into a temperature value without
backing up.
If you select Backup value, the pressure value is fixed to the value specified by Backup set
value. Set Backup set value to a value of your choice.
If you select Hold, the pressure value is held at the previous value within the proper range.
(4) Set the analog input range. Set the temperature values corresponding to 4 mA and 20 mA.
Configuration menu path:
[HART] “Detailed setup>>I/O condition>>Analog input>>AI-2(Temperature)”
[YH8000] “ >>Configuration>>I/O>>Analog Input>>AI-2(Temperature)”
5.3.5 Setting the Output Range
This section explains how to assign an item to the 4 to 20 mA analog output. For details on the
analog output hold function, see “6.4.2 Output Hold”.
Configuration menu path:
[HART] “Detailed setup>>I/O condition>>Analog output”
[YH8000] “ >>Configuration>>I/O>>Analog output”
(1) Select the output item for each channel.
On HART, the AO-1 and AO-2 output items are displayed as “PV is” and “SV is,”
respectively. On YH8000, it is displayed as “Item.” You can assign the following items to the
analog output.

*1: Selectable only with two-gas measurement specifications
*2: Displays the name of the gas component being measured.
Example: If the component being measured is oxygen: O

concentration
(2) Set the measurement item values that correspond to the minimum point (4 mA) and
maximum point (20 mA).
On HART, the minimum and maximum points are displayed as “PV LRV” and “PV URV,”
respectively.
