Add Calculated Series

Note:The Add Calculated Series functionality is only available from EMS Version 1.0.9 onwards.

When the inputs from two Sensor/Transmitter's channels can be used to calculate a Series/Plot of values of a third, derived, parameter (a Calculated Series), the Add Calculated Series link will be displayed on relevant charts. See Figure 1115 below.

For example, values for Temperature and Relative Humidity could be used to calculate values for the Dew Point Margin Margin.
