FLUXUS F70x 12 Data Logger and Transmission of Data
120 UMFLUXUS_F7V4-6-2EN, 2017-10-01
The line \DATA will be transmitted next. Afterwards the column titles will be transmitted for the respective channel (see
Tab. 12.3) The measured values are transmitted afterwards.
In every 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 of data
Columns will be created for all quantities that appear during the measurement. The columns Q_POS and Q_NEG will re-
main empty if the totalizers are deactivated.
As the totalizers cannot be activated for the physical quantity flow velocity, these columns will not be created.
Offline transmission of data
During the offline output, columns will only be created if at least one measured value is stored in the series of measured
values. The columns Q_POS and Q_NEG will not be created 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 re-
started after a 10 s interruption for the positioning of the transducers.

\*MEASURE ###000000.00 physical quantity selected in Output Options
Q_POS +00000000.00 totalizer value for the positive flow direction
Q_NEG -00000000.00 totalizer value for the negative flow direction
FQ_POS value of the totalizer for the positive flow direction (if the heat flow has been selected
as the physical quantity)
FQ_NEG the value of the totalizer for the negative flow direction (if the heat flow has been se-
lected as the physical quantity)
T1 ###000.0 temperature T1 (= supply temperature if the heat flow has been selected as the phys-
ical quantity)
