CONDITIONING
OPERA TION
CONDITIONING
OPERATION
Remove the cap. If white crystals have
formed, they will be dissolved during
conditioning.
T o condition, soak the tip of the tester in
pH 7.01 buffer solution for ten minutes.
CALIBRA TION
Calibrate your tester once a week or at
any time you suspect a problem with the
readings. ADWA pH testers can be
calibrated at 4, 7 and 10 pH values.
AL W A YS CALIBRATE A T pH 7 FIRST .
1. Put the tip of the tester in pH 7.01 buffer
solution and press the ON/OFF button.
2. Press CAL button: “7.0” and “pH” will
start flashing. When the sign “pH” stops
flashing, the reading has stabilized. Then
press READ button: “4.0” and “pH” will
start flashing.
3. Rinse the tip of the tester with deionized
water.
4. Put the tip of the tester in pH 4.01 buffer
(for acidic measurements) or in pH 10.01
buffer (for alkaline measurements): “4.0”
(or “10.0”) and “pH” will start flashing.
5. When the sign “pH” stops flashing, the
reading has stabilized. Press READ. The
calibration is completed.
AL WAYS USE A FRESH BUFFER
SOLUTION FOR CALIBRA TION.
1. Remove the protective cap from the
bottom of the tester .
2. Press ON/OFF button to turn the tester
on.
3. Place the tip of the tester into the sample
to be measured.
4. Stir the sample and record the reading
when the value has stabilized. The tester
will automatically compensate temperature
variations.
5. Press ON/OFF button to turn the tester
off.
MAINTENANCE
The sensor should be kept moist at all times.
This can be done by storing the tester with
a few drops of pH 7.01 buffer solution in
the protective cap. Rinse the electrode after
each measurement with tap water .
W ARNING: DO NOT USE DEIONIZED
OR DISTILLED W A TER FOR STORAGE
PURPOSES.
BA TTERY REPLACEMENT
When the batteries need to be replaced,
the “Eb” error message will appear on the
display and the tester will turn off automatically
to prevent the unreliable measurement result.
Open the battery compartment at the top
of the tester. Place the batteries noting the
polarity listed in the battery compartment.
Remove the cap. If white crystals have
formed, they will be dissolved during
conditioning.
To condition, soak the tip of the tester in
pH 7.01 buffer solution for ten minutes.
