• The outer junction sleeve can be removed and cleaned with purified water.
Once cleaned a small amount of supplied gel electrolyte should be added to
refresh the junction and improve the pH measurement.
Note:
Never immerse the tester over the maximum immersion level.
Refilling the Electrode
• To remove the electrode sleeve, rotate it carefully and slide it off the probe body,
keeping it parallel to the pH electrode.
Note:
Handle the probe with care, the
pH electrode stem is made of glass.
• Rinse off any traces of electrolyte
gel from the sleeve. Soak the tip in
HI700601
General purpose cleaning
solution or
HI700630
Meat, grease
and fats acid cleaning solution for
20 minutes. Rinse with distilled or
deionized.
• Refill the reference well with
HI9071
Gelled bridge electrolyte.
• Replace the sleeve making sure that the black O ring is
fixed inside the electrode.
• Rinse off excess gel with distilled or deionized water.
• Shake the probe down as you would do with a clinical
thermometer to eliminate any trapped air bubbles.
• Soak the probe in
HI70300
Electrode storage solution for a
minimum of 30 minutes before calibrating.

Auto-Off
From measurement mode, press and hold the ON/OFF
button. The LCD will show "OFF", "CAL" followed by
"d08" (default setting, 8 minutes). Release the ON/OFF
button. A single press on the ON/OFF button will change
the auto-off timer to "d60" (60 minutes). To disable the
auto-off feature press the ON/OFF button again, LCD will
show "d--". Press and hold to exit.
Clear Calibration
To clear the user calibration and restore the tester
to factory default. From calibration mode, press and
hold the ON/OFF button, the LCD will show "CLr".
“Err” Message
In calibration mode, if the probe is in the correct
buffer solution and the "Err" message is displayed, the
probe should be cleaned. Soak the probe in cleaning
solution for 20 minutes. Rinse with water and hydrate
electrode in storage solution for a minimum of 30
minutes before calibrating.
Battery Indicator
When the battery level is low, the tag on the LCD will
blink. When the battery is depleted the "Erb" message
is displayed and the tester is powered off.
Care & Maintenance
General Information
Please read the information below, to ensure the highest possible accuracy:
• Fresh buffer should be used for each calibration, once the sachets are opened
the buffer value can change over time.
• For improved accuracy a two-point calibration is recommended.
• If the electrode is slow or sluggish, soak it in cleaning solution for 20
minutes. Rinse with water and hydrate the electrode in storage solution for a
minimum of 30 minutes before calibrating.
• If measurements are taken successively, rinse the probe thoroughly in
distilled or deionized water to eliminate cross-contamination.
• When not in use, add a few drops of storage solution to the protective cap
to keep the glass tip and the junction hydrated. If storage solution is not
available, pH 4.01 or pH 7.01 buffer can be used. Never store the probe in
distilled or deionized water.
Battery Replacement
To change the CR2032 lithium-ion battery, turn
the battery cover located on the back of the tester
counterclockwise to unlock. Remove cover and
replace the battery with positive (+) side facing out.
Note:
Only use the battery type specified in
the manual. Old batteries should be disposed
in accordance with local regulations.
