In-Flight Compensation
You can configure the meter to have in-flight compensation, which can improve
alarm accuracy in some applications.
Here’s how it works....
Imagine you have a storage container and you want to empty a certain amount of
material from that container into a bin.
The meter will automatically compare the desired setpoint level to the actual
final fill or empty weight, or position, and compensate for any calculated error
for the next cycle This is a continuous process, so if material consistency varies
and the in-flight error varies, the meter automatically adapts after each operation.
For the first alarm, the meter will correct for 100% of the measured error, to get
as close to desired action as possible. Then, each time the alarm occurs, it will
correct for 25% of the previous smaller error, to reduce the effects of material
variations.
To use the inflight compensation, set Hysteresis to 9999 for the alarm channels
you need it to operate on.

When the bin reaches the desired
weight, the meter will switch off the
shutoff valve. But, a certain amount of
material is still falling into the bin, and
will add to the weight, causing an
overweight error.
