OPERATIONAL GUIDE
OPERATIONAL GUIDE
Each meter is supplied with batteries. Before using the
meter for the first time, open the battery compartment
and insert batteries, observing the polarity (see “Battery
Replacement“).
CONNECTING THE ELECTRODE
With the meter turned off, connect the HI763063 probe to
the DIN socket on the bottom of the meter by aligning the
pins and pushing in the plug firmly. Remove the protective
cap from the probe before taking any measurements.
TURNING 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, displaying “WAIT“ until electrode
check is in process then the meter enters the normal
measurement mode.

OPERATIONAL GUIDE
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 line
with “---“ blinking on the first LCD line.
- If the readings are out of range, the nearest range limits
are displayed blinking (e.g. 3999 μS -5.0 °C).
SELECTING MEASUREMENT RANGE
While in measurement mode, press the SET button to select
EC or TDS measurement on the first LCD line.
FREEZING MEASUREMENT VALUES
While in measurement mode, press and hold the SET
button until “HOLD“ appears on the secondary LCD. The
“HOLD” remains for 1 second and reading of EC/TDS and
temperature will be frozen on the LCD with “H” blinking.
→
Press any button to resume active measurements.
ENTERING CALIBRATION MODE
Press and hold the button until ”POWER” and tag
is replaced by “STD“ and tag. Release the button.
ENTERING SETUP MODE
Press and hold button until “STD“ and tag is
replaced by “SETUP“ and tag. Release the button.
TURNING THE METER OFF
Whileinmeasurement mode,pressthe button.”POWER”
and tag will appear. Release the button.

EC MEASUREMENT & CALIBRATION
Rinse the electrode off well with
distilled or deionized water. Shake
off excess droplets. PLace the probe
in the sample to be tested. Use plastic
beakers or containers to minimize any
electromagnetic interference. Tap the probe lightly on the
bottom of the beaker or container to remove air bubbles that
may be trapped inside the tip. Wait for a few minutes for
the temperature sensor to reach thermal equilibrium, when
the tag disappears. The LCD displays the EC or TDS 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.
EC calibration
Before calibration, rinse the sensor
tip with a heavy stream of distilled
or deionized water. Shake off excess
droplets.
Select calibration “STD“ . The meter enters the
calibration mode and “μS 1.41 USE” (HI99300) or
“mS 12.88 USE“ (HI99301) is displayed with tag
blinking. Place the sensor in calibration solution. If the
standard value is recognized first “REC“ then “WAIT“
is displayed until the calibration is accepted. The LCD
will display “SAVE” for 1 second and return to normal
measurement mode. If the standard is not recognized or the
reading is out of accepted range “--- WRONG“ is displayed.
After the calibration procedure has been completed, the
“CAL“ is displayed.
Note: - βshould be set to 1.9 during calibration.
- There is a known relationship between the EC and
TDS readings, it is not necessary to calibrate the meter
in TDS. The meter will allow a calibration in TDS using
HI70032 or HI70038 TDS calibration solution.

OPERATIONAL GUIDE
Exiting calibration and resetting default values
After entering the calibration mode and before the 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 point is accepted.
The LCD displays “CLEAR“ for 1 second, the meter resets
to the default calibration and the “CAL“ on the LCD
disappears.

METER SETUP
METER SETUP
Setup mode allows the selection of the Temperature unit,
Auto‑off, Beep confirmation tone, temperature compensation
factor for EC and TDS conversion factor. To enter Setup mode
press and hold button until “STD“ and tag is
replaced by “SETUP“ and tag. Release the button.
• “TEMP“ is displayed on the
secondary LCD line with the current
temperature unit (e.g. “TEMP °C“),
for °C/°F selection, use the SET
button. After the temperature unit has
been selected, press to confirm
and to enter the “A-OFF“ selection.
• Use the SET button, to navigate
through the auto‑off choices: 8
minutes (“8”, default value), 60
minutes (“60”) or disabled (“---”).
Press to confirm and to enter the
“BEEP“ selection.
• To switch the beep tone ON or OFF,
press the SET button; press to
confirm and to enter the EC
temperature compensation factor
selection “BETA“.
• The meter will show the current
factor “1.9” on the primary LCD and
“BETA” on the secondary LCD.
Change the set factor with the SET
button. Press to confirm and to
enter TDS conversion factor “CONV“.
• The meter will show the set
conversion factor “0.50” on the
primary LCD and “CONV” on the
secondary LCD. Change the set
conversion factor with the SET
button. Press to confirm and to
return to normal mode.

BATTERY REPLACEMENT
When the remaining battery life is less
than 10% the battery tag blinks on the
display to warn the user.
Battery Error Prevention System (BEPS)
If the battery is too weak (“0%”) the display shows “bAtt“,
“DEAD“ for a few seconds then the meter powers off.
Immediately replace the batteries with new ones.
The batteries are accessed by opening the battery cover
on the back of the instrument. Remove protective boot
if present.
Replace the three 1.5V AAA alkaline batteries located in
the battery compartment, observing the indicated polarity.
Replace the battery cover making sure that the gasket is
in place.
