Offset correction
- with unpressurized sensor
- parallel shift of the adjust-
ment characteristics
Real value correction
- with available percentage
value
- parallel shift of the adjust-
ment characteristics
Density correction
- only in conjunction with
hydrostatic pressure
transmitters
- slope correction of the
adjustment characteristics
