Functional description
This function displays the p-factor.
The p-factor indicates the influence of the velocity distribution of the flow profile inside
the pipe; it is dependent on the Reynolds number. The p-factor varies in the range
0.75 to 0.95. If the displayed value ranges between 0.75 and 0.94 the measurement
will have a reduced linearity.
Use this function to call up or manually change the zero point correction currently
being used.
User input
5-digit floating-point number, including unit and sign (e.g. +10.0 ns)
Use this function to enter a correction factor at the client's site.
User input
5-digit floating-point number
Factory setting
1.0000 (= no correction)
!
Note!
This option is not available unless INSERTION was selected in the function
MEASUREMENT (6880). (is not supported by the measuring device)
Use this function to enter a deviation value for the sensor distance.
User input
5-digit floating-point number, including unit and sign (e.g. +2.0000 mm)
Factory setting
0 mm
Use this function to enter a deviation value for the arc length.
