13.2.5 Advanced diagnosis
There are further diagnostic values available for the calculation channels. These can either be transmitted via the outputs
of the transmitter or defined as source of the event trigger.
13.3 SuperUser mode and SuperUser ext. mode
Some menu items that are not visible in the StandardUser or ExpertUser mode are now displayed.
In the SuperUser ext. mode it is not possible to carry out any plausibility test of the entered parameters.
13.3.1 Pig detection
This function detects pigs inside the pipe. The pig detection can be activated/deactivated via the HotCode 007028
(default: deactivated).
Deviating from the global device settings, the pig detection for particular channels can be activated or deactivated.

13.3.2 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

is displayed.
• Select
Off

• Select
Default
if no customized inputs are to be made.
• Select
On
to define the values for the pipe wall calibration.
• Press ENTER.
Notice!
The SuperUser and SuperUser ext. mode is intended for experienced users with advanced application knowledge.
Changed parameters can affect the StandardUser mode and lead to wrong measured values or to a failure of the
measurement when setting up a new measuring point.
Notice!
Some of the defined parameters remain activated when switching to the StandardUser mode. These parameters are
displayed but cannot be changed.
