G. Conductivity/Resistivity Calibration mode
The model 3321 uses 1-point calibration for conductivity or resistivity.
In the
Measure mode
, pressing
[UP]
key and
[ENTER]
key at the same time to allow
the meter to go to the
Conductivity / Resistivity calibration mode
.
At the
Conductivity / Resistivity calibration mode
, the “
CAL
” icon and a
conductivity/resistivity reading will display. Rinse the conductivity probe in distilled
water and immerse it into the standization solution. Allow temperature reading to
stabilize, press
[UP]
key or
[DOWN]
key to change this reading to that of the
