Hanna Instruments HI 700 Series - Manual (Page 5)

INSTALLATION
HI 700 and HI 710
series offer a multitude
of possibilities, from
single and dual set-
points to ON/OFF or
PID dosage, isolated
outputs with user-select-
able zoom, bi-directional
RS485, recorder outputs
in mAmps and Volts.
Use the 3-wire Pt 100
temperature sensor to
compensate for the
cable resistance and
have a precise auto-
matic temperature
compensation of the
measurements in long
distance applications.
See the diagram for a
recommended installa-
tion.
