OPERATIONAL GUIDE

TO TURN THE METER ON

To turn the meter ON, press the button on
the front of the meter. If it does not turn on, make
sure that the batteries are properly installed in their place.
The meter is provided with an active acoustic signal when
a key is pressed. At start‑up the meter displays all LCD
segments for a few seconds, followed by the percentage
indication of the remaining battery life, the meter enters
the normal measurement mode.

Note: The meter detects the presence and the type of
the probe at its input.

- If the probe is not connected the message “NO”
”PROBE“ appears alternatively on the secondary LCD
with “---“ blinking on the first LCD line.

- If the probe is not compatible “WRONG” ”PROBE“
message appears alternatively on the secondary LCD
with “---“ blinking on the first LCD line.

- If the readings are out of range, the nearest range limits
are displayed blinking (E.g. -2.00 pH -5.0 °C).

TO SELECT THE MEASUREMENT RANGE

While in measurement mode, press the SET button to select
pH or pH‑mV measurement on the first LCD line.

TO FREEZE THE MEASUREMENT VALUES

While in measurement mode, press and hold the SET

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
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.
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† to eliminate cross‑contamination.

OPERATIONAL GUIDE

For better accuracy, frequent calibration of the pH sensor
with the meter is recommended. In addition, the meter
must be recalibrated whenever:
a) The pH electrode is replaced.
b) After testing aggressive chemicals.
c) Where high accuracy is required.
d) At least once a month.
e) After cleaning the sensor.

†

The probe tip should be rinsed with purified water (reverse osmosis,

distilled, or deionized) before and after placing in any solution (buffer,
storage, or sample).

pH calibration

Enter calibration mode while in
pH measurement mode. Place the
sensor into the first calibration
buffer. If performing 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 blinking (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.
It is always recommended to carry out a two‑point
calibration for better accuracy.

When the calibration procedure is completed, the tag
is turned on together with the calibrated points.

To exit calibration and reset 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.

OPERATIONAL GUIDE

13

ELECTRODE CONDITION

The display is provided with a probe icon (unless the fea‑
ture 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 150 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.
