CONDITIONING:
Remove the cap and immerse the TE 10
in storage solution for 2 hours to activate
the electrode.
CALIBRATION:
Unscrew the battery compartment cap on the
top of the meter and perform one of the following
two-point calibration procedure, according to
the required application:
Acid calibration for measurements below pH7:
• Immerse the electrode in pH7.01
buffer solution.
• Allow the reading to stabilize and
with a small screwdriver turn the
“7” calibration trimmer inside the
battery compartment until the
display shows "7.0".
• Rinse the electrode with tap water
and immerse it in pH4.01 buffer
solution.
• Allow the reading to stabilize and with a small
screwdriver turn the “4” calibration trimmer
until the display shows "4.0".
Alkaline calibration for measurements above pH7:
• Immerse the electrode in pH7.01 buffer so-
lution.
• Allow the reading to stabilize and with a small
screwdriver turn the “7” calibration trimmer
until the display shows "7.0".
• Rinse the electrode with tap water and immerse
it in pH10.01 buffer solution.
• Allow the reading to stabilize and with a small
screwdriver turn the “4” calibration trimmer
until the display shows "10.0".
Replace the battery compartment cap.
OPERATION:
• Remove the protective cap.
• Turn the TE 10 on by pressing the ON key.
• Immerse the electrode in the solution to be
tested.
• Stir gently and wait for the reading
to stabilize.
• After use, rinse the electrode with
water to minimize contamination.
• Store the electrode with a few
drops of storage or pH7 solution
in the protective cap.
• Always replace the protective cap after use.
NEVER USE DISTILLED OR DEIONIZED
WATER FOR STORAGE PURPOSES.
ELECTRODE REPLACEMENT:
The electrode can be easily replaced in the
following way:
• Remove the protective cap.
• Unscrew the plastic ring on the
top of the electrode.
• Pull out the TE73600 pH electrode
and replace it with a new one
(aligning the colored pin towards
the LCD side).
• Make sure the gaskets are in
place before screwing back the
ring.
BATTERY REPLACEMENT:
TE 10 is supplied with BEPS (Battery Error
Preventing System) which avoids any erroneous
reading due to low battery level, by switching
the meter off. To replace the batteries unscrew
the battery compartment cap and replace all
three 1.5V batteries while paying attention to
their polarity. Make sure the gasket is in place
before screwing back the cap.
Batteries should only be replaced in a
nonhazardous area using the battery type
specified in this instruction manual.
