Menu Diagnostics v-Paths
This menu is used to view information on hardware and current sensor/path data (see Fig.
41-1). There is no simulation available in this menu.
The transmitter starts the menu with an overview. You can jump to the individual v-paths from
this overview.
The following settings/current values are available/readable:
•
>v-Path x<
Individual measured velocities
The right function key (Tab) can be used to view each path individually.
Prerequisite: at least one 2-path measurement must be available.
•
>Raw value<
Actual measured value
•
>Median valid<
A check mark indicates that the respective path operates within the usual limits. If no
check mark is set, the path yields atypical values / outliers.
•
>Delta t<
Measured transit time difference; the transmitter uses this value to compute the
velocity (v)
•
>Transit t<
Average signal transit time between sensor 1 and sensor 2 of the according path
•
>Path temperature<
Calculated medium temperature of the according path
•
>SonicPro T Resistor<
This section shows whether the SonicPro T overvoltage protection can be installed
without the need for constructional modifications (screen: “---”) or whether a modifica-
tion is required (screen: “red” or “blue”).

•
>Alignment<
Tool for sensor positioning and thus for path alignment:
>Dist.<
(Distance):
Indicates via the arrow pointer whether the parameterized sensor position needs to
be corrected because of the actual operating conditions (move together or further
away from each other). In the green area the sensor position is optimal, in the yellow
and red areas it needs to be adjusted.
