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
or calibrating, and stir briefly the electrode in tap water to remove the
storage solution. 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 HI70300 storage solution
for 30 minutes to reactivate it.
• To take a pH measurement simply
submerge the tip (4 cm/ 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.
OPERATIONAL GUIDE

• 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 compensat-
ed 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 (4 cm/ 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 HI700661
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 recom-
mended. 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 (HI9813-6 only).
PREPARATION
Pour small quantities of pH7.01 (HI7007) or pH4.01 (HI7004) or
pH10.01 (HI7010) solution into a clean beaker.
To obtain accurate readings, use pH7.01 (HI7007) if you are going
to measure neutral or close to neutral samples, pH4.01 (HI7004) if
you are going to measure acidic samples or pH10.01 (HI7010) for
alkaline measurements.
If you need to calibrate to NIST standards, use pH6.86 (HI7006) instead
of pH7.01 and pH9.18 (HI7009) instead of pH10.01.
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.
pH CALIBRATION

10
For temperature compensation during calibration, please refer to the
following chart.
pH VALUES AT VARIOUS TEMPERATURES
For instance, if the buffer temperature is 25 °C, the display should
show pH4.0 or 7.0 or 10.0.
If the buffer temperature is 10 °C, the display should show pH4.0 or
7.0 or 10.1.
TEMP pH VALUES

Accessories needed:
• Use HI70031 (1413 µS/cm = 1.413 mS/cm) EC calibration
solution or HI70442 (1500 ppm) TDS calibration solution.
Note:The conversion between EC and TDS is made by a built-in circuit,
hence it is requested to calibrate the meter only in EC or TDS
range. The other range is thus automatically calibrated.
PROCEDURE
• Pour approximately 4cm(1½”) of a conductivity calibration solution
(e.g. HI7031) into a beaker. If possible, use plastic beaker to
minimize any EMC interference.
• Immerse the probe in the solution.
• Wait for a couple of minutes for thermal equilibrium to be reached.
• Tap the probe on the bottom, then shake it lightly while rotating
to make sure no air bubbles remain trapped inside the probe.
• Press the mS/cm (or ppm) key.
• Turn the EC/TDS calibration knob until the display shows the EC or
TDS reading at 25 °C.
EC/TDS CALIBRATION

PROBE MAINTENANCE
These meters are powered by a 9V battery that is located on the rear
of the instrument.
When battery symbol is empty a low battery condition is indicated.
When the low battery indication appears, only a few hours of working
time remains.
It is recommended to replace the battery immediately.
When the battery level is so low that it may cause unreliable measure-
ments, the meter turns off.
Battery replacement must only take place in a nonhazardous area using
a 9V alkaline battery.
Unscrew the three screws on the rear of the meter, remove the battery
compartment cover and replace the 9V battery with a new one while
observing its polarity.
Make sure the battery contacts are tight and secure before replacing
the cover.
BATTERY REPLACEMENT
PERIODIC MAINTENANCE
Inspect the probe and the cable. The cable used for the connection to the
meter must be intact and there must be no points of broken insulation
on the cable or cracks on the probe stem or bulb.
Connector must be perfectly clean and dry. If any scratches or cracks are
present, replace the electrode. Rinse off any salt deposits with water.

13
CLEANING PROCEDURE
For better accuracy in measurements and to ensure a good performance
of the probe, a frequent cleaning is recommended.
For this purpose, soak it in Hanna Instruments HI700661 Cleaning
Solution for 5 minutes.
Note:For particular dirt (as for example protein, oil or grease) see the
“Accessories” section for Hanna Instruments specific solutions.
HI9813-6 only:
CAL CheckTM FEATURE / CLEAN & CAL PROCEDURE
The unique CAL CheckTM feature allows the user to check the meter
calibration status at any time. Simply follow the below procedure for
a quick and easy operation.
• Rinse the probe with water.
• Immerse the probe in the HI50021 check solution.
Note: If the reading is around pH4.0, the probe is broken and has to
be replaced.
• Press the Check key.
• If the meter is calibrated “Probe is OK”
message is displayed.
• If cleaning is needed “Clean Probe and
Calibrate” message is displayed:
1. immerse the probe in the HI700661
cleaning solution (or in one of the
available specific solutions - see
“Accessories” section) for 5 minutes,
then rinse it with tap water.
2. immerse again in the HI50021 check
solution and press the CHECK key.
3. if the message “Probe is OK” is
displayed, the meter does not need
calibration.
4. if the message “Clean Probe and Calibrate” is displayed
again, calibration is needed (see “pH Calibration” section).
Notes:• If it is not possible to calibrate, the probe has to be replaced
with a new one.
• For field applications, it is always recommended to keep a
spare probe handy. When anomalies are not resolved with
simple maintenance, change the probe and recalibrate the
meter.
