Attempting to enter a conversion that references an object (point, PE function etc) results in error..
"Could not validate conversion formula"
By design in SBO a point conversion can not contain references to other objects in the server.
Remove the reference and substitute a hard coded value
sqrt(elecvalue) * kfactor
In the conversion above, 'kfactor' is an analog value in the b3, the conversion can't be validated due to the reference to kfactor.
The solution is to replace 'kfactor' with its actual value
sqrt(elecvalue) * 10
