OPERATING

• Remove the
protection cap.

• Turn the CD97 on
with the ON/OFF
switch located on the
top.

• Immerse into solution
up to the maximum
immersion level without
touching the bottom of
the beaker.

• Stir gently and wait
until the display
stabilizes. CD97
compensates for the
temperature variance
automatically.

• Read the value on the
display.

CALIBRATION

• The calibration
procedure is very
simple and
fast.

• Immerse
the tester up
to the
maximum
level into the
appropriate
optional
calibration
solution
M10080
corresponding to 800
ppm.

• Allow the displayed
value to stabilize.

• Pull out the battery
compartment and
locate the calibration
trimmer on the top of
the internal circuitry.

• By turning the
calibration trimmer with
a small screwdriver,
adjust the reading to
match the solution
value of 800 ppm
(normally to the value
at 25°C). Replace the
battery compartment in
the original position.

• Calibration is now
complete.

BATTERY
REPLACEMENT

When the CD97
cannot be
switched on or
the display
fades, pull out
the battery
compartment
and replace all
three 1.5V batteries,
paying attention to their
polarity. Batteries
should be replaced in a
non-hazardous area
using the battery types
specified in this
instruction manual.
