Settings of the HybridTrek mode
The HybridTrek mode combines the TransitTime mode and the NoiseTrek mode. During a measurement in the Hy-
bridTrek mode, the transmitter automatically toggles between the TransitTime mode and the NoiseTrek mode depending
on the gaseous or solid content in the fluid in order to receive valid measuring values.
If there are valid measured values in the NoiseTrek mode, the transmitter can periodically toggle to the TransitTime mode
in order to check if a measurement in the TransitTime mode is possible again. The time interval and the duration of the
check of the TransitTime mode are set as follows:
In order to toggle manually between the TransitTime and NoiseTrek mode during the measurement, press key
when
the measuring mode is displayed.
Note!
Due to its higher measuring accuracy, the TransitTime mode should be used preferentially over the
NoiseTrek mode.

Select
no
to deactivate the automatic toggling between the TransitTime and the NoiseTrek
mode. If

is selected, the NoiseTrek mode can only be activated and deactivated manu-
ally during the measurement.
Select

mode. The NoiseTrek mode can also be activated and deactivated manually during the
measurement if

Press ENTER.
This display will only be indicated if the NoiseTrek mode is enabled and the NoiseTrek par-
allel beam mode has not been activated.
If the automatic toggling between the TransitTime and the NoiseTrek mode is activated, the
toggling parameters have to be configured.
Enter the time after which the transmitter has to toggle to the NoiseTrek mode if there are
no valid measured values in the TransitTime mode. If
0
(zero) is entered, the transmitter
does not toggle to the NoiseTrek mode.
Enter the time after which the transmitter has to toggle to the TransitTime mode if there are

Enter the time after which the transmitter has to toggle to the TransitTime mode. If

is entered, the transmitter does not toggle to the TransitTime mode.
Enter the time after which the transmitter has to toggle from the TransitTime mode back to
the NoiseTrek mode if there are no valid measured values.
Example:
TT-Failed
NoiseTrek: After 40s
NT-Failed
TransTime: After 60s
NT-Ok,but check TT: Each 300s
Keep TT checking: For 5s
If no measurement is possible in the TransitTime mode within 40 s, the transmitter toggles to the NoiseTrek
mode. If no measurement is possible in the NoiseTrek mode within 60 s, the transmitter toggles back to the
TransitTime mode.
If valid measured values are obtained during the measurement in the NoiseTrek mode, the transmitter tog-
gles to the TransitTime mode every 300 s. If no measurement is possible in the TransitTime mode within
5 s, the transmitter toggles back to the NoiseTrek mode. If a valid measured value is obtained in the
TransitTime mode within 5 s, the transmitter continues the measurement in the TransitTime mode.
