PRELIMINARY EXAMINATIONGENERAL DESCRIPTION and INTENDED USE
HI9814 is a durable, portable pH, conductivity, total dissolved
solids and temperature meter for most measurements
encountered in hydroponics, aquaponics or general
agriculture applications. All operations and settings, are
made through only two buttons. The housing is water‑
proof and rated for IP67 conditions.
The supplied HI1285‑7 multiparameter probe measures pH,
EC/TDS, and temperature in one convenient, rugged probe.
A preamplifier is integrated into the probe to protect the
pH measurement from transient electrical noise. Sources
of electrical noise include ballasts used in lighting and
pumps to circulate water and nutrient solutions. Other
user‑selectable features include selectable TDS factors
of 0.5 and 0.7 as well as auto‑off after 8 minutes or
60 minutes to prolong battery life.

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“).
CONNECT THE PROBE
Withthemeterturned off, connecttheHI1285‑7probeto 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.
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.

Electrode
check
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.
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 third LCD.
- If the probe is not compatible “WRONG” ”PROBE“
message appears alternatively on the third LCD line
with “---“ blinking on the first LCD line.
Note: A HI12943 pH probe may be used on this meter
but conductivity reading will not be displayed. “---“and
“NoEC“ message will be displayed.
- If the readings are out of range, the nearest range
limits are displayed blinking (E.g. -2.00 pH -5.0 °C).
OPERATIONAL GUIDE
To enter calibration mode
Press and hold the button until ”POWER” and
tag is replaced by “QUICK“ tag if quick calibration
is selected from setup menu, or “PH STD“ tag or
“EC STD“ tag if standard calibration is selected from
setup menu. Release the button.
To enter Setup mode
From a measurement screen press and hold button until
“STD“ and tag is replaced by “SETUP“ and
tag. Release the button.
To turn the meter OFF
Whilein measurementmode,pressthe button.”POWER”
and tag will appear. Release the button.

OPERATIONAL GUIDE
METER SETUP
Setup mode allows configuration of parameters: Temperature unit,
Auto‑off, Calibration type, Beep confirmation tone, pH Resolution,
pH calibration Information and TDS conversion factor.
• “TEMP“ is displayed on the third 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 cycle through the
auto‑off choices: 8 minutes (“8”, default
value), 60 minutes (“60”) or disabled
(“---”). Press to confirm and to enter
the calibration type selection.
• tag is displayed. Use the SET
button to choose from “STD“ (standard
calibration) or “QUICK“ (one‑point
quick calibration). Press to confirm
and to enter the “BEEP“ selection.
• To switch ON or OFF the beep tone,
press the SET button; press to con‑
firm and to enter electrode calibration
information “INFO“ selection.
• To switch ON or OFF the electrode
condition indicator on the LCD, press
the SET button; press to exit setup
options; Change the set with the SET
button, then press to confirm and to enter TDS conversion
factor “CONV“.
• “CONV“ is displayed on the third
LCD line with the current TDS factor
(E.g. “0.50“), for selecting, “0.70“
TDS factor use the SET button. Press
to confirm and to return to normal mode.
pH MEASUREMENT
Make sure the meter has been calibrated before use.
If the probe is dry, soak it in HI70300 storage solution for
a minimum of 30 minutes to reactivate it.

10
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, the EC, TDS or pH‑mV
value on the secondary LCD, while the third LCD line displays
the sample temperature.
If measurements are taken in different
samples successively rinse the probe
tip thoroughly†to eliminate cross‑
contamination. 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 probe.
†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).
Follow directions for single and two‑point calibration below:
SECOND LINE MEASUREMENT
While in measurement mode, press the SET button to
scroll between EC, TDS or mV of pH measurement on the
secondary LCD.
EC MEASUREMENT
Rinse the probe tip off with lots of clean water to remove
storage solution, buffers or samples. Shake off any drop
lets that remained. 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 container to remove air bubbles that may be
trapped inside the tip.
