Totalizer / ...Lag Correction
Mode Selection of overrun correction.
Closing the fill valve takes some time and as a consequence more liquid is added, even though the fill quantity is reached
and the contact for closing the valve is actuated.
• Manual: The overrun quantity is calculated by the transmitter automatically.
• Auto: The overrun quantity must be determined manually and entered in the selected unit via the parameter ‘Quantity’.
Quantity Manual input of the overrun quantity / display of the overrun quantity detected automatically by the transmitter.
Factor The menu is visible when ‘Mode’ is set to ‘Auto’.
Sets the weighting of the last filling process during automatic calculation of the overrun quantity.
The calculation is based on the following formula:
New correction value = last correction value + (BatchAuto.Lag Corr.Factor × correction value at the last filling)
• 0.0: No change to correction value.
• 1.0: The correction value is immediately adjusted to the overrun quantity calculated during the last fill operation.
Value range: 0 to 1
Time Sets the time for the overrun quantity correction after the fill valve is closed.
Value range: 0.1 to 10° sec.
