B Loop Current
User can define initial and final set point values for
respective Conductivity / TDS and Temperature
using loop current. Controller offers isolated Loop
currents with range from 4 ~ 20mA. This isolated
loop current has an accuracy of 0.01mA which
makes this controller accurate in measurements and
control.

Conductivity / TDS which can be feed by pressing enter after
selection of value tab. Press upward and downward button
for increment and decrement in main value 1

press forward button for increment in main value 2
nd
digit
by 1. If the value goes in 3 digits than forward button will
increase the 2
