Depending on the storage interval, one data line per activated measuring channel is transmitted. The line "???" will be
transmitted if there are no measured values available for the storage interval.
The following data columns can be transmitted:
Online transmission
Columns will be created for all quantities appearing during the measurement. The columns Q_POS and Q_NEG remain
empty if the totalizers are deactivated.
As the totalizers cannot be activated for the physical quantity "flow velocity", these columns will not be generated.
Offline transmission
During the offline transmission of data, columns will only be created if at least one measured value is stored in the data
set. The columns Q_POS and Q_NEG will not be generated if the totalizers are deactivated.
Example
\DATA
A: \*MEASURE; Q_POS; Q_NEG;
B: \*MEASURE; Q_POS; Q_NEG;
Example
With a storage interval of 1 s, 10 lines with "???" will be transmitted if the measurement has been restarted after a 10 s
interruption for the positioning of the transducers.
