Offset 
P851 Measurement Offset 
The  value  of  this  parameter  is  added  to  the  measured  distance,  in 
Measurement Units (P104). 
This Offset will be added to the level, as derived from the transducer, and will 
affect everything including the reading on any display in use, relay setpoints 
and the output. 
Temperature 
P852 Temperature Source 
This parameter determines the source of the temperature measurement. By 
default, it is set to automatic (P852=1), which will automatically detect if a 
temperature sensor  is available  from the transducer. If for any reason,  no 
temperature input is received, then the Fixed Temp value is used, as set by 
P854. 
The temperature source can be specifically set as follows:  
Will automatically select transducer 
temperature sensor, if available, or fixed 
temperature (P854) if no temperature 
sensor found. 
 
P854 Fixed Temperature  
This parameter sets the temperature, in degrees centigrade to be used if P852 
(Temperature Source) =2. Default = 20
