mA Output (LOOP) Menu 
P834 mA Low Level 
This  parameter  sets,  in  Measurement Units (P104),  the value  of  ‘level’, 
‘space’ or ‘distance’, depending on the selected Mode of Operation (P100), 
at which 4mA will occur.   
P835 mA High Level  
This  parameter  sets,  in  Measurement Units (P104),  the  value  of  ‘level’, 
‘space’ or ‘distance’, depending on the selected Mode of Operation (P100), 
at which 20 mA output will occur. 
P838 mA Low Trim 
If the device you are connected to is not calibrated, and not showing the low 
value, then you can trim it using this parameter. You can either type in the 
offset directly, or use the arrow keys to move the output up and down until 
you get the expected result on the device that is connected. 
P839 mA High Trim 
If the device you  are connected to is not  calibrated, and not  showing the 
high value, then you can trim it using this parameter. You can either type in 
the offset directly, or use the arrow keys to move the output up and down 
until you get the expected result on the device that is connected. 
P840 mA Fail-safe 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:
