The level unit may differ from the distance unit defined in the Distance unit parameter
(→  144):
• The unit defined in the Distance unit parameter is used for the basic calibration (Empty
calibration (→  146) and Full calibration (→  147)).
• The unit defined in the Level unit parameter is used to display the (unlinearized) level.

• For rod and rope probes up to 8 m (26 ft): 200 mm (8 in)
• For rod and rope probes above 8 m (26 ft): 0.025 * Sondenlänge
For FMP51/FMP52/FMP54 with the Interface measurement application package
