Relationship

The two single components measuring cell and electronics both have a non-volatile
memory (EEPROM). Each contains a data structure which is permanently assigned
to the measuring cell or the electronics. Measuring cell data (e.g.: measuring range,
measuring cell material, oil filling etc.) are stored in the measuring cell's EEPROM.
Data of electronics (e.g.: turn-down, electric damping etc.) are in the electronic's 
EEPROM. Using the mode "factory calibration", please note that after exchanging a
component, the parameters seen in Table 2, page 49 are restored with the stated
values.
