• 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.
• Press ENTER.
Turbulence mode
The activation of the turbulence mode can enhance the signal quality if the flow is highly turbulent (e.g., in the vicinity of an
elbow or valve). An SNR value of min. 6 dB is required during the measurement.
• Select the menu item Special settings in the program branch Options.
• Press ENTER until the menu item Turbulence mode is displayed.
•Select On to activate or Off to deactivate the turbulence mode.
•Select Default if no user-defined inputs are to be made.
• Press ENTER.
Multi-point calibration
It is possible to enter a series of measured values in order to define a calibration curve for the flow velocity.
Record of series of measured values:
• Start a measurement with the transmitter and a reference flowmeter.
• Gradually increase the value of the flow velocity. The measured range of values has to be identical with the eventual op-
erating range.
• Note or store the measured values.
Input of measured values:
• Select the menu item Special settings in the program branch Options.
• Press ENTER until the menu item Multi-point calibration is displayed.
•Select Yes to define the calibration curve. Select No to measure without calibration.
• Press ENTER.
• Enter the number of pairs of measured values.
• Press ENTER.

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 toggles to the
TransitTime mode every 300 s. If no measurement is possible in the TransitTime mode for the duration of 5 s, the trans-
mitter 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.
