Setting Unit and Conversion for
Manual Sensors
Unit conversion is valid for float type of manual sensors only. For
string type manual sensors, there is no need for conversions. For
integer type manual sensors, rounding causes unnecessary errors.
In addition to defining the unit, you can also define a conversion from
the input value to another unit. For example, you can define the input
parameter as air pressure, but instead of entering it in the unit of hecto-
Pascals, it can be entered in the unit of inches of mercury.
For example, to define a unit conversion for the manual sensor
measuring air pressure, proceed as follows:
1.
Enter pressure data in inches of mercury.
2.
The manual sensor component converts air pressure to hecto-
Pascals, so that all the predefined pressure calculations will also
work for this manually entered data.
