Trim 
P1 and P2 
P*838 mA1 Low Trim 
If the remote device you are connected to is not calibrated, and not showing 
the correct low value (reading), 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 (reading) on the remote 
device that is connected. 
P*839 mA1 High Trim 
If the remote device you are connected to is not calibrated, and not showing 
the correct high value (reading), 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 (reading) on the remote 
device that is connected. 
Failsafe 
P1 and P2 
P*840 mA1 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 (P1-808), but this can be overridden to force the mA output 
to an independent fail-safe mode as follows:
