Example:
Level 100 %:
4000 mm
Density: 1 g/cm3
Density correction: 0.9 g/cm3
Span end point:
The span (end-point) must be re-calibrated (with or without pressure) to 4000 mm in
order to prevent a 4000 mm level tank from being overfilled.
Please check the following if "Wrong Entry" appears in the Evaluation
menu:
• whether or not more than 32 value pairs are entered in the table for tank
linearization (please note: P 0 and P 31 are fixed at 0% and 100% re-
spectively)
• whether or not an existing height value was tried to be stored again
Please enter correct values.
A change or correction in the density causes a change in the span end-
point’s unit of measure (mm, m, inch, feet). The span end-point must be
re-calibrated when changing the medium to be measured (due to a
change in density).
