OPERATIONAL GUIDE
pH MEASUREMENT & CALIBRATION
Make sure the meter has been
calibrated before use.
If the probe is dry, soak it in
HI70300 storage solution for
30 minutes to reactivate it. If
soiled, 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.
Rinse the electrode off well and shake off excess droplets.
Recalibrate before using. Submerge the probe in the sample
to be tested while stirring it gently. Wait until the tag
on the LCD disappears.
The LCD displays the pH value (automatically compensated
for temperature) on the primary LCD, while the secondary
LCD displays the sample temperature. If measurements are
taken in different samples successively, rinse the probe tip
thoroughly in distilled or deionized water to eliminate cross‑
contamination.
Press any button to resume active measurements.

OPERATIONAL GUIDE
For better accuracy, frequent calibration of the pH sensor
with the meter is recommended. In addition, the meter
must be recalibrated:
a) whenever the pH electrode is replaced.
b) after testing aggressive chemicals.
c) when high accuracy is required.
d) at least once a month.
e) after cleaning the sensor.
pH calibration
Enter calibration mode while in pH measurement mode.
Place the sensor into the first calibration buffer. If perform‑
ing a two‑point calibration, use pH 7.01 (pH 6.86 for NIST)
buffer first. The meter will enter the
calibration mode, displaying “pH
7.01 USE” and tag blink‑
ing (or “pH 6.86 USE” for NIST).
Follow directions for single and
two‑point calibration below:
Single-point calibration
1. Place the probe in any buffer from the selected buffer set.
The meter will automatically recognize the buffer value.
2. If the buffer is not recognized or the calibration offset is out
of the accepted range “---- WRONG“ is displayed.
3. If the buffer is recognized “REC“ is displayed then
“WAIT“ until the calibration is accepted.
If using pH 7.01 (or pH 6.86 for NIST), after acceptance
of the buffer press any key to exit. The ”SAVE” message is
displayed and the meter returns to pH measurement mode.
If using pH 3.00 or 10.01 (or pH 9.18 for NIST) buffer
the ”SAVE” message is displayed and meter returns to pH
measurement mode.

12
Two-point calibration
Proceed with steps 1 through 3 under single‑point
calibration using 7.01 (pH 6.86 for NIST) pH buffer
first. Then follow steps below:
The ”pH 3.00 USE” message is then displayed.
Place the probe in the second calibration buffer (pH 3.00
or 10.01, or, if using NIST, pH 3.00 or 9.18). When the
second buffer is accepted, the LCD will display “SAVE”
for 1 second and the meter will return to the normal
measurement mode.
If the buffer is not recognized or the slope is out of accepted
range ”--- WRONG” is displayed. Change the buffer, clean
the electrode or press any key to exit calibration.
For better accuracy it is always recommended to carry
out a two‑point calibration.
After the calibration procedure has been completed, the
tag is turned on together with the calibrated points.
Exiting calibration and resetting default values
After entering the calibration mode and before the first point
is accepted, it is possible to quit the procedure and return
to the last calibration data by pressing the button. The
LCD displays “ESC“ for 1 second and the meter returns to
normal mode.
To reset the default values and clear a previous calibration,
press the SET button after entering the calibration mode
and before the first point is accepted.
The LCD displays “CLEAR“ for 1 second, the meter resets to
the default calibration and the tag with the calibrated
points on the LCD disappears.

13
ELECTRODE CONDITION
The display is provided with a probe icon (unless the
feature is disabled from setup) which indicates the electrode
status after calibration. The “condition” remains active for
12 hours (unless the batteries are removed).
The electrode condition is evaluated only if the current
calibration has two points.
5 bars: excellent condition
4 bars: very good condition
3 bars: good condition
2 bars: fair condition
1 bar: poor condition
1 bar blinking: very poor condition
With 1 bar it is recommended to clean the electrode and
recalibrate. If there is still only 1 bar or 1 bar blinking
replace the probe.
Sensor check
Setting the meter to pH‑mV range the user can check the
sensor status at any time. The offset value is the reading
in pH 7.01 buffer (@ 25 °C/77 °F). If this reading is
outside the range ±30 mV, the electrode is considered
“very poor”. The slope value of the sensor is the difference
between readings in pH 7.01 and in pH 3.00 buffers. When
the slope reaches the value of about 200 mV, the electrode
is considered “very poor“. When “poor“ or “very poor“, it
is recommended to replace it with a new one.
Note: To ensure reliable readings, the electrode must
be cleaned with cleaning solution and then hydrated in
storage solution for a minimum of 30 minutes before
calibrating the probe.
