In addition, the validity of the settings should be verified:
Open the "Meter status" window and go to the tab "Advanced or Path Status" (
). If a lamp for "Time plausibility" is on, it indicates an incorrect zero phase.

Go to the "Meter values" page to check that the measured SOS values are almost the
same at all paths of the FLOWSIC600, and that they differ by less then 0.1%
(
).
Switch between display of absolute and difference SOS by clicking the right mouse
button on the SOS graph and using the context-menu.
Check that the measured SOS deviates no more than 0,3% from a theoretical SOS,
which is calculated from gas composition, pressure and temperature (
).

SOS per path on the "Meter values" page (left: absolute SOS , right: difference to average)
In the case of very low gas velocities (< 1 m/s or 3 ft/s), there may be more
significant differences between the paths due to thermal stratification. In this
case, the SOS on the upper paths (1 and 2) will be higher than the lower paths.
