VIN Low Error - Can we add a delay or disable the error

We have had multiple issues using ratiometric sensors that end up sending voltages below the 0.5 threshold. If the input drops to 0.250 then the system throws a VIN low error. The error value only exists for an instant. The sensor output is jumpy. I wish we could add some averaging, signal stabilization or add a delay on the error to filter out these events. Or maybe we could define the low error value instead of using the minimum/2. 

In retrospect, it realize I could have set the range to 0 V and extrapolated the value of the output to keep the calibration the same, but I cannot do this on an existing program because the min and max outputs are not part of the calibration.

Put the vin in a function group and enable it after delay
