Hanna Instruments Foodcare HI981034 Instruction Manual

Care and Maintenance
To obtain the highest accuracy for measurements it is important to follow these tips:
• Calibration is only as good as the buffer being used. The pH buffer values change over
time once the sachets are opened. Fresh buffer should be used for each calibration.
• The probe should be rinsed with purified water each time before placing in buffer or
sample to be tested.
• When the meter is not in use it is important to add several drops of storage solution
to the protective cap to keep the probe hydrated. If storage solution is not available,
pH 4.01 or pH 7.01 buffer can be used.
• For improved accuracy it is recommended to calibrate in two buffers.
• It is important to calibrate and measure samples at the same temperature. A dramatic
change in temperature between buffer solutions and samples to be tested will give
.
inaccurate readings
• If fouled, clean the electrode by soaking in cleaning solution for 20 minutes, then
rinse the tip and soak in storage solution at least 30 minutes before use. Recalibrate
after each cleaning.

ON/OFF until "CLr" is displayed. The meter will
now be at default calibration.
"Err" Message
In calibration mode, if the meter displays an
"Err" message when in the correct fresh buffer
solution then the probe should be cleaned.
Place the probe in the
solution for 20 minutes. Rinse with purified water
and place in storage solution for a minimum of
30 minutes before calibrating.
Battery Indicator
RoHS
compliant

the battery is running low, the tag will blink on
screen. When the battery has been depleted,
"Erb" will appear on screen and the meter will
turn off.
