General Description
HI9814 is designed to offer you the combination of pH,
conductivity, total dissolved solids, and temperature
measurements. All operations and settings, including
calibration buffers and temperature scale selections,
are made through only two buttons. The housing
is waterproof and rated for IP67 conditions.
Maintenance:
The supplied HI1285-7 multiparameter probe measures
pH, EC/TDS, and temperature in one convenient, rugged
probe. A solid-state 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, 60 minutes, or disabled.
• After use, rinse the electrode with water and replace the
protective cap filled with a few drops of HI70300 storage solution. If HI70300 is not available, use pH buffer.
• While unpacking, the appearance of salt deposits
around the protective cap is normal. The salt deposits
will dissolve when rinsed with water.
DO NOT USE DISTILLED OR DEIONIZED WATER FOR
STORAGE PURPOSES.

“----CLR“ for 1 second, the meter resets to the default calibration and the “Calibrated” tag on the LCD disappears.
pH Measurement and Calibration†
• Make sure the meter has been calibrated before use.
• If the probe is dry, soak it in HI70300 storage solution
for 30 minutes to reactivate it.
• Submerge the probe in the sample to be tested while
stirring it gently. Wait until the “Not Stable“ tag on the LCD disappears.
• The LCD displays the pH 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† to eliminate cross-contamination. After cleaning, rinse
the probe tip with some deionized water and some of
the sample to be measured.
Note: Keeping the ON button pressed while turning the
meter on will display all LCD segments as long as the button
is pressed.

• Enter calibration mode.
• Immerse the probe in the HI9814-0 calibration solution.
• When the standard value is recognized and stability is
reached the meter automatically accepts the calibration.
• The LCD will display “OK” for 1 second and return to normal measurement mode.
•
If the standard is not recognized or the slope is out
of accepted range “---- WRNG“ is displayed. Change the
calibration solution, clean the electrode or press any key
to exit calibration.
• When the calibration procedure is completed, the
“Calibrated“ tag is turned on.
To exit calibration and reset 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 ON/OFF/MODE
button. The LCD displays “---- ESC“ for 1 second and the
meter returns to measurement mode.
Select calibration type “CAL STD“ from meter setup.
• Place the sensor into the first calibration buffer. If performing a two-point calibration, use pH 7.01 buffer first.
Follow directions for single and two-point calibration below:
Single-point calibration
1. Place the probe in any buffer from the selected buffer set.
The meter will automatically recognize the buffer value.
2. If the buffer is not recognized or the calibration offset
is out of the accepted range “---- WRNG“ is displayed.
3. If the buffer is recognized “REC“ is displayed until the
reading is stable and the calibration is accepted.
• If using pH 7.01, after acceptance of the buffer press any
key to exit. “OK1“ message is displayed and meter returns
to pH measurement mode.
• If using 4.01 or 10.01 buffer the “OK1“ message is
displayed and meter returns to pH measurement mode.
Two-point calibration
Proceed with steps 1 through 3 under single-point calibration
using 7.01 pH buffer first. Then follow steps below:
• The “pH 4.01 USE“ message is then displayed.
•
Place the probe in the second calibration buffer
(pH 4.01 or 10.01). When the second buffer is accepted,
the LCD will display “OK2” for 1 second and the meter will return to the normal measurement mode.
•
If the buffer is not recognized or the slope is out of
accepted range “---- WRNG“ is displayed. Change
the buffer, clean the electrode or press any key to
exit calibration.
Note: When the calibration procedure is completed,
the “Calibrated“ tag is turned on.
It is always recommended to carry out a two-point
calibration for better accuracy.
EC Measurement and Calibration†
• 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.
• Wait for a few minutes for the temperature sensor
to reach thermal equilibrium, when the “Not Stable“
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.
EC calibration
Select calibration type “CAL STD“ from meter setup.
• Enter calibration mode while in EC measurement mode.
• The meter enters the calibration mode and “USE”
is displayed. Immerse the probe in 1.41 mS/cm or
5.00 mS/cm calibration solution.
• If the standard value is recognized ”REC” is displayed
until the reading is stable and calibration is accepted.
• The LCD will display “OK” for 1 second and return to
normal measurement mode.
•
If the standard is not recognized or the slope is out
of accepted range “---- WRNG“ is display. Change the
buffer, clean the electrode or press any key
to exit calibration.
• When the calibration procedure is completed, the
“Calibrated“ tag is turned on.
Battery Replacement
The meter is supplied with batteries.
The meter displays the remaining battery percentage
when turned on. When the level is below 5%, the
symbol on the LCD blinks to indicate a low battery condition.
If the battery level is low enough to cause erroneous
readings, the Battery Error Prevention System (BEPS) turns
the meter off. It is recommended to replace the batteries as
soon as the display flashes the battery symbol. To replace
the batteries:
• Open the battery compartment cap (on the bottom of
the instrument).
• Remove old batteries.
• Replace new batteries, observing the polarity on the
rear of the instrument.
• Close the battery compartment cap.
† 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).
