Example:
Setting
• P711 = 2, material agitator
• P712 = 5:2
Result
• a new reading will not be validated unless five consecutive measurements higher or
two consecutive measurements lower than the current reading occur
• Resetting P711 returns P712 to the respective preset values
P713 Echo Lock Window
Adjusts the size of the Echo Lock Window.
The Echo Lock Window is a distance window (units P005) centred on the echo and used
to derive the Reading. When a new measurement is in the window, it is re-centred and
the new Reading calculated. Otherwise, the new measurement is verified by Echo Lock
(P711) before the reading is updated.
When 0 is entered the window is automatically calculated after each measurement. For
slower P003 Maximum Process Speed values the window is narrow, for faster P003
values the window becomes wider.
Transducer Scanning (P725 to P729)
P726 Level System Sync
Enables the System Sync on the terminal block.
Use this if another level measurement system is mounted nearby, and they are wired
together on the Sync terminal.
P727 Scan Delay
The delay, in seconds, between measurements from transducer points .
