HI9032 is an auto-ranging TDS meter,
and the reading automatically switches from
one resolution to the next (from 0.00mg/l
up to 19.99 g/l).

When using HI 7686 together with HI 7669/
2W all readings are automatically compen-
sated for any temperature difference. Wait
for a few minutes for the temperature sen-
sor to attain thermal equilibrium with the
test solution before taking the measure-
ment. If the temperature of the conductivity
probe and the solution is drastically apart,
a longer time should be allowed before tak-
ing readings.

Immerse the HI7686 probe in the solution
submerging the holes of the sleeve into
the liquid. Tap the probe lightly on the
bottom of the recipient to remove any air
bubbles which may have being trapped
inside the sleeve.
