• If the pig detection has been deactivated in the global device settings and the measurement is to be carried out with pig
detection on this channel, select On for this channel.
• Press ENTER.
• If the pig detection has been activated in the global device settings and the measurement is to be carried out without pig
detection on this channel, select Off for this channel.

14.3.2 Pipe wall calibration for Lamb wave transducers
The parameter record of a measuring channel for Lamb wave transducers has a calibration factor for the uncorrected flow
velocity. This calibration factor depends on the pipe material.
The pipe wall calibration for Lamb wave transducers becomes effective if the following criteria are met when starting a
measurement:
• Lamb wave transducers are used
• pipe wall calibration is activated
• a factor for the pipe material is defined and selected from the program branch Parameters
The factor can be activated in the transmitter.
• Select the menu item Special settings in the program branch Options.
• Press ENTER until the menu item LWT pipe wall calibr. is displayed.
•Select Off to measure without pipe wall calibration.
•Select Default if no customized inputs are to be made.
•Select On to define the values for the pipe wall calibration.
• Press ENTER.
Some of the defined parameters remain activated when switching to the StandardUser mode. These parameters are
displayed but cannot be changed.
If the analysis is activated, not all settings are applicable.
