INFORMATION!
The procedure that follows calibrates the new device. You must have 2 reference points (levels)
in the tank given by a different measurement solution (an approved level meter or indicator).
These points are identified as reference point 1 (R1) and reference point 2 (R2). R1 is the point
where the tank is approximately 20% full. R2 is the point where the tank is approximately 80%
full.
