13.4 Settings of the HybridTrek Mode
The HybridTrek mode combines the TransitTime mode and the NoiseTrek mode. During a measurement in the HybridTrek
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
checking are set as follows:
In order to toggle manually between the TransitTime mode and the NoiseTrek mode during the measurement, press key
ENTER 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 Special Funct.\SYSTEM settings\Measuring. Press ENTER until the list
item Enable NoiseTrek is displayed. NoiseTrek mode on to enable the NoiseTrek
mode, off to disable it. Press ENTER.
Select no to deactivate the automatic toggling between the TransitTime and the NoiseTrek
mode. If no is selected, the NoiseTrek mode can only be activated and deactivated manu-
ally during the measurement.
Select yes to activate the automatic toggling between the TransitTime and the NoiseTrek
mode. The NoiseTrek mode can also be activated and deactivated manually during the
measurement if yes is selected.
Press ENTER.
This display will only be indicated if the NoiseTrek mode is enabled.
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
no valid measured values in the NoiseTrek mode. If 0 (zero) is entered, the transmitter
does not toggle to the TransitTime mode.
Enter the time after which the transmitter has to toggle to the TransitTime mode. If 0 (zero)
is entered, the transmitter does not toggle to the TransitTime mode.
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.
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 for the duration of 40 s, the transmitter toggles to
the NoiseTrek mode. If no measurement is possible in the NoiseTrek mode for the duration of 60 s, the
transmitter toggles back to the TransitTime mode.
If there are valid measured values during the measurement in the NoiseTrek mode, the transmitter toggles
to the TransitTime mode every 300 s. If no measurement is possible in the TransitTime mode for the dura-
tion of 5 s, the transmitter toggles back to the NoiseTrek mode. If a valid measured value is obtained in the
TransitTime mode within the duration of 5 s, the transmitter continues the measurement in the TransitTime
mode.
