Couplings When this value is change, the reference level will be changed based on:
Ref Level = Min Grid Level +10* Scale/Div
The value of bottom grid level will be recalculated based on the exact Ref Level value.
Similar to Ref Level, the allowed range of Grid Level set is affected by the Ref Level Offset Value.
