PRELIMINARY EXAMINATION

5
HI99300 and HI99301 are conductivity, total dissolved
solids and temperature measurement encountered in man‑
ufacturing and environmental testing protocols.
To increase precision, two models are available, with dif‑
ferent conductivity ranges, for applications from purified to
brackish waters.
All operations, settings and temperature scale selections,
are made through only 2 buttons.
The housing is waterproof and rated for IP67 conditions.
The supplied multi‑parameter probe, HI763063, includes
EC/TDS and temperature in one convenient, rugged probe.
Other user selectable features include different TDS factors
from 0.45 to 1.00, and a range of temperature coefficients
(b) from 0.0 to 2.4% for better solution temperature com‑
pensation.

DISPLAY DESCRIPTION

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“).
TO CONNECT 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.
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, displaying “WAIT“ until electrode
check is in process then the meter enters the normal mea‑
surement 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.
- If the probe is not compatible “WRONG” ”PROBE“ mes-
sage 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).
TO SELECT THE MEASUREMENT RANGE
While in measurement mode, press the SET button to select
EC or TDS measurement on the LCD.
TO FREEZE THE MEASUREMENT VALUES
While in measurement mode, press and hold the SET
button until “HOLD“ appears on the second LCD line for
1 second. The reading of EC and temperature will be frozen
on the LCD with “H” blinking.
Press any button to resume active measurements.

TO ENTER CALIBRATION MODE
Press and hold the button until ”POWER” and tag
is replaced by “STD“, tag if standard calibration is
selected from setup menu. Release the button.
TO ENTER SETUP MODE
Press and hold button until “STD“ and tag is re‑
placed by “SETUP“ and tag. Release the button.
TO TURN THE METER OFF
Whileinmeasurementmode,pressthe button.”POWER”
and tag will appear. Release the button.
EC MEASUREMENT AND CALIBRATION
Placetheprobeinthesampletobetested.
Use plastic beakers or containers
to minimize any electromagnetic
interference. Tap the probe lightly on
the bottom of the 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 tem‑
perature) on the primary LCD, while the secondary LCD dis‑
plays the sample temperature.

EC calibration
Before calibration, rinse the sensor
tip with a heavy stream of purified
water then shake excess water from
the probe.
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. Immerse the probe in calibration
solution. If the standard value is recognized “REC“ is displayed
then “WAIT“ 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
slope is out of accepted range “--- WRONG“ is display.
Change the calibration solution, clean the electrode or press
any key to exit calibration. When the calibration procedure is
completed, the “CAL“ tag is turned on.
Note: - Beta should be set to 1.9 during calibration.
- Since there is a known relationship between the EC and
TDS reading, it is not necessary to calibrate the meter in
TDS. If the conversion factor is either 0.5 or 0.7, the meter
will allow a direct calibration in TDS by using the Hanna
calibration solutions.

• Use the SET button, to cycle 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 ON or OFF the beep tone,
press the SET button; press to
confirm and to enter the calibration
buffer selection “BETA“.
SETUP MODE
Setup mode allows the selection of the Temperature
unit, Auto‑off, Beep, 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“isdisplayedonthesecondary
LCD line with the current temperature
unit (E.g. “TEMP °C“), for °C/°F se‑
lection, use the SET button. After the
temperature unit has been selected,
press to confirm and to enter the “A-OFF“ selection.
METER SETUP
• “BETA“is displayedon thesecondary
LCD line with the current temperature
compensation factor (E.g. “1.9“),
use SET button to modify the value.
Press to confirm and to enter TDS
conversion factor “CONV“.
• “CONV“isdisplayedonthesecondary
LCD line with the current TDS factor
(E.g. “0.50“), for selecting other
value use the SET button. Press
to confirm and to return to normal
mode.

Replace the battery cover making sure that the gasket is
in place.
Replace the three 1.5V AAA alkaline batteries located in
the battery compartment, observing the indicated polarity.
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 few seconds then the meter power 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.
