• Enter a limit of the flow velocity for the measurement in flow direction.
• Press ENTER.
If the flow velocity is higher than this limit, it will be marked as invalid. The physical quantity cannot be determined.

• Enter a limit of the flow velocity for the measurement against the flow direction.
• Press ENTER.
If the flow velocity is lower than this limit, it will be marked as invalid. The physical quantity cannot be determined.

1 – physical quantity
2 – flow velocity
Notice!
If the limit of the flow velocity
+Flow velocity limit
is too low or
-Flow velocity limit
is too high,
a measurement might be impossible because most of the measured values will be marked as invalid.

Notice!
A reduced threshold value allows for measurements under difficult conditions, but increases the risk of measurement
errors.
