1. If volume strapping table is used, make
sure level values within operating
range are included.
2. If scaled variable table is used, make
sure input variable values within
operating range are included.
1. Check configuration of Bottom Product
Dielectric Constant.
2. Check configuration of Reference
Height and Bottom Offset.
3. If not needed, disable Tank Bottom
Projection.
