The Turbidity or Suspended Solids LINEAR analog output is based

on the following equation:

mA

(Turbidity or Suspended Solids)

= 4mA+(16mA)*(D

(Turbidity or Suspended Solids )

-

Turbidity or Suspended Solids (4) ) /Turbidity or Suspended Solids

(20) - Turbidity or Suspended Solids (4))

Where:

mA

(Turbidity or Suspended Solids)

= analog output

D

(Turbidity or Suspended Solids)

= current Turbidity or Suspended Solids display

Turbidity or Suspended Solids(4)

=Turbidity or Suspended Solids user setting for 4 mA

Turbidity or Suspended Solids(20)

= Turbidity or Suspended Solids user setting for 20 mA.
