mA Failsafe 
P840 mA Failsafe Mode 
This parameter determines what happens to the mA output in the event of 
the unit going into fail-safe mode. The default is to do the same as the 
system fail-safe (P808), but this can be overridden to force the mA output 
to an independent fail-safe mode as follows:  
mA output will fail as per P808 
mA output will retain its last known value.  
mA output will fail to its low condition. 
mA output will fail to its high condition. 
 
Compensation Parameters 
Offset 
P851 Measurement Offset 
The value of this parameter is added to the measured distance, in 
Measurement Units (P104), and will affect everything including the reading 
on the display, the relay setpoints and the mA 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. 
Always uses temperature reading from transducer. 
Always uses fixed temperature (P854)
