The current output correspondence
Current = [(PV(Primary Variable)
-
Zero span) / (Full span- Zero
span)] *16mA + 4mA
e.g:
①
The Primary variable is Level (the variable is selected as
HL00), the Level value is 3.626m, the Full scale is set to
6.000m, the Zero scale is set to 0.000m, the current output is:
[(3.626-0.00)/(6.000-0.000)] *16mA +4mA = 13.67mA
PV is level value (HL00)
②
The Primary variable is distance (the variable is selected
as HL99), the distance value is 2.365m, the Full scale is set to
6.000m, the Zero scale is set to 0.500m, the current output is:
[(2.365-0.500)/(6.000-0.500)] *16mA +4mA = 9.43mA
