INITIAL PREPARATION
Each meter is supplied complete with a 9V battery. Remove the
battery compartment cover on the back of the meter and install the
battery while observing its polarity.
Connect the probe to the DIN socket on the top of the meter by
aligning the pins with the socket and pushing in the plug.
Always remove the probe protective cap before taking
any measurements, and make sure the meter has
been calibrated.
Turn the meter on by pressing the On/Off key.
TAKING pH MEASUREMENTS
If the probe has been left dry, soak the tip in HI 70300 storage solution
for 30 minutes to reactivate it.
• To take a pH measurement simply
submerge the tip (4cm/1½") of the
probe into the sample to be tested.
• Select the pH mode.
• Stir briefly and wait a couple of
minutes for the reading to adjust
and stabilize. The display shows
the pH value.
• If measurements are taken in different samples successively, it is
recommended to rinse (clean) the probe thoroughly to eliminate
cross-contamination. After cleaning, it is recommended to rinse the
probe with some of the next sample to be measured.
TAKING EC/TDS MEASUREMENTS
• Immerse the tip of the probe (4cm/1½") into the
sample to be tested. If possible, use plastic beakers
or containers to minimize any EMC interference.
• Tap the probe lightly on the bottom of the beaker
to remove any air bubbles which may be trapped
inside the tip.

• Select the appropriate measurement range (EC or TDS).
• Wait for a couple of minutes for the
temperature sensor to reach thermal
equilibrium. The display then shows the
measurement automatically compensated
for temperature with the appropriate
following indication: “mS” tag indicates
the meter is in EC mode, while “ppm”
tag indicates the meter is in TDS
mode.
TAKING TEMPERATURE MEASUREMENTS
• Submerge the tip (4cm/1½") of the
probe into the sample to be tested.
• Select the °C mode.
• Stir briefly and wait a couple of minutes
for the reading to adjust and stabilize.
The display shows the temperature
value.
Notes: • If the display shows only a “1”
on the far left hand side, the
reading is out of range.
• It is recommended to clean
often the probe with HI 700661
Cleaning Solution.
• After measurements have been completed, the instrument
should be switched off, and the probe cleaned and
covered with the protective cap.

9
For greatest accuracy, frequent calibration of the instrument is
recommended. The instrument should be recalibrated for pH:
a) Whenever the electrode is replaced.
b) At least once a month.
c) After testing aggressive chemicals.
d) Where extreme accuracy is required.
e) Whenever the CAL-CHECK test fails (HI 9813-6 only).
PREPARATION
Pour small quantities of pH 7.01 (HI 7007) or pH 4.01 (HI 7004)
or pH 10.01 (HI 7010) solution into a clean beaker.
To obtain accurate readings, use pH 7.01 (HI 7007) if you are going
to measure neutral or close to neutral samples, pH 4.01 (HI 7004)
if you are going to measure acidic samples or pH 10.01 (HI 7010)
for alkaline measurements.
If you need to calibrate to NBS standards, use pH 6.86 (HI 7006)
instead of pH 7.01 and pH 9.18 (HI 7009) instead of pH 10.01.
PROCEDURE
• Connect the probe and switch the meter on, then press the pH
key to display pH measurement.
•Remove the protective cap from the probe, rinse and immerse it in
the buffer and stir gently. Wait a couple of minutes for the
reading to stabilize.
• Take the temperature of the buffer solution, e.g.
10.0°C, as follow: select the °C mode and read
the displayed value.
• Adjust the pH calibration knob until
the LCD shows the pH value at the
above temperature (see the pH versus
temperature chart).
• The pH calibration is now complete.
Notes: • The probe should be submerged approximately 4 cm
(1½") into the solution. The thermometer has to be
located close to the probe.
• If turning the knob the needed value can not be reached,
clean the probe (see the “Probe Maintenance” section). If
also after the probe cleaning the value can not be
reached, replace the probe.

For temperature compensation during calibration, please refer to the
following chart.
For instance, if the buffer temperature is 25°C, the display should
show pH 4.0 or 7.0 or 10.0.
If the buffer temperature is 10°C, the display should show pH 4.0 or
7.0 or 10.1.
