Calculations View

In the Calculations view, you can select and configure meteorological

calculations and unit conversions, as well as statistical and

miscellaneous calculations; see Figure 34 on page 81.

Every calculation the QML logger makes is based on some input data.

That is, when a calculation is configured, you inform the logger which

variables are used for producing a particular calculation. To make this

task easier, Lizard gives suggestions on the correct sources and

variables. Sources can be measurement names or names of components

that manage static parameters, whereas variables are the names of the

output. Sources can include one or several variables.

Calculations have been divided into the following four categories:

meteorological calculations, unit conversions, statistical calculations,

and miscellaneous calculations. The initial input data for these

calculations comes from measurement algorithms, other calculations,

or from static parameters.
