When you can not complete AGA settings in success and found error message as below, please
refer to below and try again.
Otherwise please contact our representatives.
aa) “bW” : Bubble Warning
The error will be indicated when pulse height fluctuates during AGA setting due to fluid
conditions like air bubble contained.
In such case, you might be required flow condition change or change path method to shorter
path. (ex. V method to Z method.) Then try again AGA function.
bb) “wW” : Wave distortion Warning
The error will be indicated when required ratio of pulse height for AGA setting can not be kept due
to pipe conditions like inner corrosion.
In such case, you might be required mounting position change or change path method to
shorter path. (ex. V method to Z method.) Then try again AGA function.
