Start of the measurement
• Select the program branch
Measurement
.
• Press ENTER.
If the parameters in the program branch
Parameters
are
not valid or incomplete, the error message
Invalid
parameters
will be displayed.
Before starting the measurement, the measuring point has
to be parameterized. The transmitter performs a parameter
search and starts the measurement. If another
measurement has already been performed using the same
measuring point parameters, the measurement can be
started immediately.
• Select the list item

if the measuring point
is to be parameterized.
9.3.1
Parameter input for the measuring point
Input of the measuring point number
• Enter the number of the measuring point.
• Press ENTER.
For the activation of text input see
Special functions\Dialogs/Menus\Measuring point no.
Input of the max. flow
The expected max. flow is needed to calculate the recommended distance between the measuring barriers.
• Enter the expected max. flow.
• Press ENTER.
Adjustment of the transducer distance for transducer pair A
The recommended transducer distance for transducer pair A will be displayed. The transducer distance is measured
between the inner edges of the transducers. On very small pipes, a negative transducer distance is possible.
• Mount the transducers of transducer pair A on the pipe and adjust the transducer distance.
• Press ENTER.
