CONDITIONING:
Remove the cap and immerse the pH54 in
MA9015 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
(M10007) 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 “7.01”.
• Rinse the electrode with tap
water and immerse it in pH4.01
(M10004) buffer solution.
• Allow the reading to stabilize and with a small
screwdriver turn the “4” calibration trimmer
until the display shows “4.01”.
Alkaline calibration for measurements above pH7:
• Immerse the electrode in pH7.01 (M10007)
buffer solution.
• Allow the reading to stabilize and with a
small screwdriver turn the “7” calibration
trimmer until the display shows “7.01”.
• Rinse the electrode with tap water and immerse
it in pH10.01 (M10010) buffer solution.
• Allow the reading to stabilize and with a
small screwdriver turn the “4” calibration
trimmer until the display shows “10.01”.
Replace the battery compartment cap.
OPERATION:
• Remove the protective cap.
• Turn the pH54 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 (MA9015) or pH7
(M10007) 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 MA73600 (or
MA73600-S) pH electrode and
replace it with a new one (align-
ing the colored pin towards the
LCD side).
• Make sure the gaskets are in place before
screwing back the ring.
BATTERY REPLACEMENT:
The pH54 is going to turn off when the bat-
teries are to weak. 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 nonhaz-
ardous area using the battery type specied
in this instruction manual.
WARRANTY:
This meter is warranted from all defects in materials and manufac-
turing for a period of two years. The electrode is warranted for
a period of one year. During this period, the required repair or
replacement of parts, where the damage is not due to negligence
or erroneous operation by the user, will be effected free of charge.
