(*) Calculated measures available only for E-Log datalogger with firmware from 2.13.1 version;
calculated measures associated with 3DOM software from 3.8 version.
These measure are set a fixed update time of 1 second: the update of value of calculated measure on
the actuator is always 1 second delay compared to the status recorded by internal actuation logic.
Now is therefore possible to process and record the actuator status or display it as an instantaneous
value without having to carry the electrical signal of the actuator in an input of the datalogger. Now
it is also possible make complex algorithms through a combination of actuation logics status with
other calculated measures (typically addition and multiplication), overcoming the limits of the use
of a single operator (AND and OR) and giving the inputs for the acquisition of real sensors.
With
3DOM you can choose which quantities to have the instrument calculate and select the direct
measures which allow their calculation.
Some calculations, frequently used in agro-meteorology, such as wind direction or integral
radiation, are easily obtained from the integral mathematical calculation.
