What to do if Unipulse F701+ show Gross over?
If your Unipulse Measuring Instruments display 'Gross over', reduce the input signal from the load cell until the over scale display disappears. Alternatively, change the gross over setting value. To prevent error displays, set the gross over setting value to the same value as the capacity.
What to do if Unipulse Measuring Instruments show Net weight over?
If the Unipulse Measuring Instruments display 'Net weight over', reduce the input signal from the load cell until the over scale display disappears, or change the net over setting value. To prevent error display, set the net over setting value to the same value as capacity.
What to do if Unipulse F701+ display Capacity + 9 scales over?
If your Unipulse Measuring Instruments show 'Capacity + 9 scales over', reduce the input signal from the load cell until the over scale display disappears.
What to do if Unipulse F701+ A/D converter input over?
If your Unipulse Measuring Instruments show 'A/D converter input over', confirm that the load cell output does not exceed the span calibration range and that the cable which connects F701+ to the load cell is not disconnected. This issue may also occur if nothing is connected to the load cell connector on the rear panel.
What to do if Unipulse F701+ Measuring Instruments A/D converter minus over?
If your Unipulse Measuring Instruments display 'A/D converter minus over', confirm that the load cell output is not below the span calibration range and that the cable which connects F701+ to the load cell is not disconnected. This may also appear if nothing is connected to the load cell connector on the rear panel.
