Setpoint 
By default, the mA Output will represent the empty (0 or 4mA dependant 
on (P830) mA Range) and 100% of the operational span (20mA), but you 
may wish to have the output represent a section of the operational span. For 
example, the application has an operational span of 6 metres but output is to 
represent empty (0 or 4mA dependant on (P830) mA Range) to a level of 
5 metres (20mA). If so P834 (Low Level) should be set to 0.00 metres and 
P835 (High Level) should be set to 5 metres.  
P834 mA Low Level 
This parameter sets the level, distance or space, depending on the selected 
mA Out Mode (P831) at which the low mA output will occur (0 or 4mA 
dependant on (P830) mA Range)  
Default = 0.000m 
P835 mA High Level  
This parameter sets the level, distance or space, depending on the selected 
mA Out Mode (P831) at which the high mA output will occur (20mA).                          
Default = 6.000m 
Limits 
P836 mA Low Limit 
This parameter  sets  the lowest level that  the  mA  output  will  drop  to,  the 
default is 0mA, but you can override this if the device you connect to cannot 
for example accept less than 2mA, yet you want to use the 0-20mA range. 
Default = 0.00mA
