OPERATION

• Remove the protective cap. Do
not be alarmed if white crystals
appear around the cap. This is
normal with pH electrodes and
they dissolve when rinsed with
water.

• Turn the meter on sliding the
switch on the top.

• Immerse into solution up to
the max immersion level.

• Stir gently and wait until the
display stabilizes.

• After use, rinse the electrode
with water to minimize con­tamination and store it with a
few drops of storage (HI70300)
or pH 7 (HI 7007) solution in
the protective cap.

DO NOT USE DISTILLED OR DEIONIZED
WATER FOR STORAGE PURPOSES.

• Large fluctuations in readings could be due
to lack of calibration, dry electrode or run­down batteries.

Recommendations for users

Before using this product, make sure that it is entirely
suitable for the environment in which it is used. Operation
of this instrument in residential areas could cause
interference to radio and TV equipment. The glass bulb
at the end of the pH electrode is sensitive to electrostatic
discharge. Avoid touching this glass bulb at all times. Any
variation introduced by the user to the supplied equipment
may degrade the instrument's EMC performance. To avoid
electrical shock, do not use this instrument when voltages
at the measurement surface exceed 24 Vac or 60 Vdc.
To avoid damage or burns, do not perform any
measurement in microwave ovens.

CALIBRATION

• Immerse the tester up to the maximum
immersion level in pH 7 buffer (HI 7007)

• Allow the reading to
stabilize; using a
small screwdriver
adjust the pH7 cali­bration trimmer to
read 7.0.

• Rinse the electrode with water and
immerse up to the maximum level in
pH 4 (HI 7004) or pH 10 (HI 7010).

• Allow the reading
to stabilize and
adjust the pH4/10
calibration trim­mer to read 4.0
(or 10.0).

Calibration is now complete.

ALWAYS USE FRESH BUFFERS FOR CALIBRATION.

BATTERY REPLACEMENT

When the meter cannot be
switched on or the display
fades, pull out the battery com­partment and replace all three

1.5V batteries, while paying

attention to their polarity.
Batteries should only be re­placed in a safe area using
the battery type specified in
this instruction manual.
