Troubleshooting
• In calibration mode, the “--- Err” message is displayed if the reading is
outside accepted range or buffer solution is not recognized.
• If the probe is not in buffer solution, “pH 14.00” or “pH 0.00” is displayed
blinking.
• If measured temperature is outside accepted range, “0
°
C” or “50
°
C” is
displayed blinking.
Care & Maintenance
Please read the information below to ensure highest possible accuracy.
• Fresh buffers should be used for each calibration, once the sachets are open
the buffer value can change over time.
• If the measurements are taken sucessively, rinse the probe thoroughly in
purified water to eliminate cross-contamination.
• When not in use, add a few drops of storage solution to the protective cap to
keep the junction hydrated. If storage solution is not available, pH 4.01 or pH
7.01 buffer can be used.
• For improved accuracy, a two-point calibration is recommended.
• When dirty, the junction can be pulled out to expose a fresh section. Pull
out 3 mm (1/8”) of the cloth, making sure that the reference compartment
remains covered. This procedure can be repeated approximately 9 times,
renewing the tester’s life.
• If the electrode or junction is dirty, soak the tip in
HI7061
General purpose
cleaning solution for 30 minutes. Rinse with distilled water and follow
cleaning procedure.
Film deposits and other impurities that accumulate with use must be removed
periodically off the membrane or junction.
•
General:
Soak in
HI7061
General cleaning solution for approximately 1 hour.
•
Protein:
Soak in
HI7073
Protein cleaning solution for 15 minutes.
•
Inorganic:
Soak in
HI7074
Inorganic cleaning solution for 15 minutes.
•
Oil & grease:
Rinse with
HI7077
Oil and grease cleaning solution.
Note:
After performing any of the cleaning procedures rinse the electrode
thoroughly with distilled water, and soak in
HI70300
Storage solution for
at least 1 hour before taking measurements.
Battery Replacement
Battery life percentage indicator is displayed at power on. If the battery
level drops below 10%, the battery symbol starts blinking. If the battery is
discharged, “dEAd bAtt” is displayed and then the tester turns off.
