Miscellaneous Calculations

Miscellaneous calculations include, for example, an accumulator option

for calculating annual precipitation (see section Accumulator

Calculation with Predefined Reset Time on page 88). Furthermore, you

can select the Timer option to create timed events that are more freely

configurable than the timers set in the Timers view (see section Timers

View on page 131).

Setting up Calculations

To select a calculation, proceed as follows:

1. Choose between Meteorological, Unit conversion, Statistical,

and Miscellaneous calculations by clicking the correct button

below the Available list box.

2. Click on an item name in the Available list box.

3. Either drag it into the Selected list box or click the Add button.

4. The name of the selected calculation is automatically highlighted

suggesting that it can be changed to a more descriptive one.

To configure a calculation, proceed as follows:

1. Click on a calculation in the Selected list box. The corresponding

editable text boxes appear in the Configure frame.

2. Select the Source and the Variable for the parameters from the

corresponding combo boxes. Only the sources and variables with

suitable measurement units are shown.

NOTE

If a source has only one variable option, the variable will automatically

appear in the variable text box when the source is selected. If this is not

the case, a variable has to be selected from the combo box.

NOTE

The Configure frame of certain calculations, such as generic statistics,

includes an extra Configuration Item frame as shown in Figure 35 on

page 85. You can use the buttons in this frame to add and remove

configurable items as an Advanced user. For further information, see

section Generic Statistical Calculations on page 158.
