OPERATIONAL GUIDEOPERATIONAL GUIDE
INITIAL PREPARATION
The meter is supplied with batteries (for details see page 19).
To prepare the instrument for use, connect the pH electrode and the
temperature probe to the BNC and temperature sockets on the top of
the instrument. The temperature probe can be used independently to
take temperature measurements, or it can be used in conjunction
with the pH electrode to utilize the meter's Automatic Temperature
Compensation (ATC) mode. If the probe is disconnected, temperature
can also be set manually with the ARROW keys.
Turn the instrument ON by pressing ON/OFF.
At start-up the display will show all LCD segments and then the
battery percentage while the instrument performs a self check (or as
long as the button is held).
The meter will automatically enter measurement mode.
After measurement switch the meter off. Clean the electrode and store
it with a few drops of HI 70300 storage solution in the protective cap.
To save the batteries, the auto-off feature turns the meter off
after 20 minutes (no button pressed). To disable this feature, see
“Setup Menu” section on page 16.
The LCD will show the pH measurement and the temperature of the
sample.
In order to take more accurate pH measurements, make sure that the
instrument is calibrated (see page 10 for details).
The glass bulb and the junction on your electrode should always be
moist, never allow it to dry out.
If several measurements are taken successively in different samples,
rinse the electrode thoroughly with deionized or tap water and a
small amount of the sample to be measured.
The pH reading is directly affected by temperature. In order for the meter
to measure the pH accurately, temperature must be compensated for. If
the sample temperature is different from the temperature at which the pH
electrode was kept, allow a few minutes for thermal equilibration.
To use the meter's Automatic Temperature Compensation feature,
submerse the temperature probe into the sample as close to the
electrode as possible and wait for a few minutes.
If manual temperature compensation is desired the temperature
probe must be disconnected from the instrument.
The display will show the default temperature of 25 °C, or the last
temperature set the “°C” (or “°F”) indicator will blink.
The temperature can now be adjusted with the ARROW keys.
pH MEASUREMENTS
To take a pH measurement remove the electrode
protective cap and submerse the electrode and
the temperature probe 3 cm (1¼”) into the
sample and stir gently.
If necessary, press the RANGE key until the
display shows pH mode.
Allow time for the reading to stabilize.
6 7
3 cm
(1¼”)
ORP MEASUREMENTS
To perform ORP measurements, connect an optional ORP electrode
(see “Accessories“ section) to the meter and turn it ON.
If necessary, enter the “mV” mode by pressing RANGE.
Submerse the ORP electrode 3 cm (1¼”) into the sample to be tested
and wait for the reading to stabilize.
Measurements within the ±699.9 mV range are displayed with 0.1 mV
resolution, while outside this range the resolution is 1 mV.
Note: While in MEM mode, the user can switch between pH and mV
by pressing the RANGE key.
A stored value can be recalled by pressing MR: the display will show
the memorized reading and the “RECALL MEMORIZED” tag, as
long as the MR key is pressed.
Note: MR will only display the range that was active when MEM was
pressed.
The ATC (or MTC) key is turned off because the mV readings are not
temperature compensated.
For accurate ORP measurements, the surface of the electrode must be
clean and smooth. Pretreatment solutions are available to condition
the electrode and improve the response time (see “Accessories“ section).
Notes:
• When the reading is out of range, the display will flash the closest
full-scale value.
• If using a pH electrode while in mV mode, the meter will measure
the mV generated by the pH electrode.
MEM & MR FUNCTIONS
Pressing the MEM key will memorize the reading on the display and
store it in the internal memory. The pH (mV) and temperature,
electrode condition and the buffers used for calibration will be stored.
The “MEMORIZE” tag blinks and the display remains frozen until the
MEM key is pressed again.
BACKLIGHT FEATURE
The meter is provided with a Backlight feature,
which can be easily accessed through the LIGHT
key.
Note: The backlight automatically shuts off after approximately 1 minute
of nonuse.

H CALIBRATIONH CALIBRATION
It is recommended to calibrate the instrument frequently, if high
accuracy is required.
The instrument should be recalibrated:
• Whenever the pH electrode is replaced.
• At least once a week.
• After testing aggressive chemicals.
• When extreme accuracy is required.
• When the calibration time-out is expired (if feature is enabled).
PROCEDURE
The meter offers a choice of 7 memorized buffers (1.68, 4.01, 6.86,
7.01, 9.18, 10.01 and 12.45 pH) and two user defined values, C1
and C2 (see “Custom Buffer Selection” section on page 12 for details).
• Pour a small quantity of selected buffer solutions into clean beakers.
For accurate calibration use two beakers for each buffer solution, the
first one for rinsing the electrode and the second one for calibration.
• Remove the protective cap and rinse the electrode with some of
the buffer solution to be used for the first calibration point.
TWO-POINT CALIBRATION
• Press the CAL key. The “CAL” and “ ” indicators will be
displayed. The secondary LCD will display buffer “7.01”. If a
different calibration buffer is desired (e.g. “6.86”), use the
ARROW keys to change the displayed value.
• Submerse the electrode approximately 3 cm (1¼”) into the
solution, place the temperature probe as close as possible to the
electrode and stir gently.
• The LCD will flash “WAIT NOT
READY” for 12 seconds, then:
if the reading is not close to the
selected buffer, “WRONG “ and
“WRONG ” will blink alternatively;
if it is close to the selected buffer the
meter will advise the user with an
audible signal (if enabled) when the reading becomes stable and
the display will change to “READY” and blinking “CFM”.
• Press the CFM key to confirm the calibration: the meter stores the
first calibration point; the primary LCD will show the calibrated
reading, while the secondary LCD will show the second buffer to be
used for calibration (“pH 4.01”).
If you’re going to calibrate with a different buffer, select the
desired value by pressing the arrow keys.
Note: The meter automatically skips the buffer used for the first calibration
point to avoid erroneous procedure. A difference of at least 1.5 pH
unit is required between the two buffers: once calibrated at either
pH 7.01 or 6.86, the instrument automatically ignores the other
value for the second point (same for pH 10.01 and 9.18).
• Submerse the electrode approximately 3 cm (1¼”) into the
second buffer solution, place the temperature probe as close as
possible to the electrode and stir gently.
• The LCD will flash “WAIT NOT READY” for 12 seconds, then:
if the reading is not close to the
selected buffer, “WRONG “ and
“WRONG ” will blink alternatively;
if it is close to the selected buffer the meter
will advise the user with an audible
signal (if enabled) when the reading
becomes stable and the display will change
to “READY” and blinking “CFM”.
• Press the CFM key: the value is stored in memory and the meter
returns to measurement mode. The tags corresponding to the
buffers used for calibration and the “condition” bargraph (if
enabled) will be light up.
10 11
Note: During calibration, the secondary LCD shows the selected buffer
value; press RANGE to display the buffer temperature.
Note: To clear a previous calibration and return to the default
values, press CLR at any time after entering the calibration
mode. The LCD will show “CLr CAL” for one second, and then
will return to normal measurement mode.
The LCD will show an empty bargraph to warn the user that
the meter is not calibrated.
ONE-POINT CALIBRATION
For optimum accuracy it is always recommended to perform a twopoint calibration, but for a faster operation it is also possible to carry
out a single-point calibration.
pH 7.01 or pH 6.86 (NIST) are typically used, however the meter can
be calibrated with any of the memorized calibration values.
After calibrating the first point (see two-point calibration), press the
CAL key to end the calibration procedure.
Note: With one-point calibration electrode “condition” is not available
and only the frame is shown. Calibration time-out is active.
CUSTOM BUFFER SELECTION
• The meter allows the user to calibrate with custom buffers.
• To select a custom buffer press the CUST BUF key while in calibration
mode. Use the arrow keys to set the desired value for C1 (the default
value is 7.00).
Note: To increase the speed, continuously press the ARROW keys.
• Once the desired value is reached,
press CFM to confirm the value. The
meter will continue calibration as
with memorized buffers.
• The meter will display “C2”. Use the
arrow keys to change the value of
the second custom buffer, or press
CUST BUF to select a memorized
buffer.
EXPIRED CALIBRATION
The instrument has a real time clock (RTC), in order to monitor the
time elapsed since the last pH calibration.
The real time clock is reset every time the meter is calibrated and the
“expired calibration” status is triggered when the meter detects a
calibration time-out. The CAL tag will start blinking to warn the user
that the meter should be recalibrated.
The calibration time-out can be set (see “Setup menu” section on
page 14) from 0 (function disabled) to 14 days.
For example, if a 4 days time-out has been selected the meter will
issue the alarm exactly 4 days after the last calibration.
If the expiration value is changed (e.g. to 7 days), then the alarm
will be immediately recalculated and appear 7 days after the last
calibration.
Notes:
• When the meter is not calibrated or calibration is cleared (default
values loaded) there is no “expired calibration”, and the display
always shows a blinking CAL tag.
• When an abnormal condition in the RTC is detected the meter
forces the “expired calibration” status.

The “condition” bargraph remains active for 12 hours after calibration,
then only the frame is shown.
Note: When an abnormal condition in the RTC is detected, the “condition”
is cleared and only the bargraph frame is shown on the display.
CLEAN ELECTRODE
Each time pH calibration is performed, the meter internally compares
the new calibration with the one previously stored.
When this comparison indicates a significant
difference, the “CLEAN ELECTRODE”
message blinks on the LCD to advise the
user that the pH electrode may need to
be cleaned (see “Electrode Conditioning &
Maintenance” section).
After cleaning, perform calibration.
Note: If the calibration data are cleared, the comparison is done
with the default values.

The resistance of glass electrodes partially depends on the temperature.
The lower the temperature, the higher the resistance. It takes more time
for the reading to stabilize if the resistance is higher. In addition, the
response time will suffer to a greater degree at temperatures below 25 °C.
Since the resistance of the pH electrode is in the range of 50 – 200
Mohms, the current across the membrane is in the pico Ampere range.
Large currents can disturb the calibration of the electrode for many
hours.
For these reasons high humidity environments, short circuits and static
discharges can be detrimental to a stable pH reading.
The pH electrode’s life also depends on the temperature. If constantly
used at high temperatures, the electrode life is drastically reduced.
Typical Electrode Life
Ambient Temperature 1 – 3 years
90 °C Less than 4 months
120 °C Less than 1 month
Alkaline Error
High concentrations of sodium ions interfere with readings in alkaline
solutions. The pH at which the interference starts to be significant
depends upon the composition of the glass. This interference is called
alkaline error and causes the pH to be underestimated. Hanna’s glass
formulations have the indicated characteristics.

PREPARATION PROCEDURE
Remove the electrode protective cap.
DO NOT BE ALARMED IF ANY SALT DEPOSITS ARE PRESENT. This is
normal with electrodes and they will disappear when rinsed with water.
During transport tiny bubbles of air may have formed inside the glass
bulb. The electrode cannot function properly under these conditions.
These bubbles can be removed by "shaking down" the electrode as you
would do with a glass thermometer.
If the bulb and/or junction are dry, soak the electrode in HI 70300
Storage Solution for at least one hour.

For refillable electrodes, if the refill solution (electrolyte) is more than
2½ cm (1") below the fill hole, add the appropriate Electrolyte Solution.
MEASUREMENT
Rinse the electrode tip with distilled water, submerse it 3 cm (1¼”) in
the sample and stir gently for a few seconds.
For a faster response and to avoid cross contamination of the samples,
rinse the electrode tip with the solution to be tested, before taking
any measurements.
STORAGE PROCEDURE
To minimize clogging and ensure a quick response time, the glass
bulb and the junction should always be kept moist.
When not in use, store it with a few drops of HI 70300 storage
solution in the protective cap.
NEVER STORE THE ELECTRODE IN DISTILLED OR DEIONIZED
WATER.
PERIODIC MAINTENANCE
Inspect electrode and cable. The cable must be intact. No cracks
should be seen on the electrode stem or bulb. If any scratches or cracks
are present, replace the electrode. Rinse off any salt deposits with water.
Connectors must be perfectly clean and dry.

RECOMMENDATIONS FOR USERS
Before using these products, make sure they are entirely suitable for
the environment in which they are used.
Operation of these instruments in residential areas could cause
unacceptable interferences to radio and TV equipment, requiring the
operator to follow all necessary steps to correct interferences.
The glass bulb at the end of the pH electrode is sensitive to
electrostatic discharges. Avoid touching this glass bulb at all times.
During operation, ESD wrist straps should be worn to avoid possible
damage to the electrode by electrostatic discharges.
Any variation introduced by the user to the supplied equipment may
degrade the instruments’ EMC performance.
To avoid electrical shock, do not use these instruments 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.
