ZERO POINT ADJUST Description
Use this function to start automatic zero point adjustment.
"
Caution!
Prior to performing zero point adjustment, observe the exact procedure for zero
point adjustment as specified in Operating Instructions BA00115D/06.
!
Note!
• Programming is locked during zero point adjustment and the display shows
the notice message #561 "ZERO-ADJ. RUN".
• If the zero point adjustment is not possible, due to unstable flow conditions,
then the alarm message #451 "ZERO-ADJ.N.OK" is shown on the display.
• After Zero point adjustment is completed, the new zero point can be called
up with the
F
key. If the
F
key is pressed again, you return to the ZERO
POINT ADJUST function.
• RESET restores the factory calibration.
• If the status input is appropriately configured, the zero point adjustment can
also be activated by using the status input (see the ASSIGN STATUS INPUT
function

INSTALLATION FACTOR Description
Disturbances in the flow may arise due to the design of the system, such as pipe
bends, reducers, etc. The flow value measured is scaled by entering a constant
factor. The flow disturbance can thus be compensated using the calculated flow
signal:
Flow output = measured flow × installation factor
Enter a higher value: flow value output is increased.
Enter a lower value: flow value output is decreased.
