OPERATIONAL GUIDE
To connect the probe
With the meter turned off, connect the HI 1414D
probe to the DIN socket on the top of the meter by
aligning the pins and pushing in the plug. Tighten
the nut to ensure a good connection. Remove
the protective cap from the probe before taking
any measurements.
To turn the meter ON and check the battery
status
Press the ON/OFF/MODE button until the display
lights up. At start-up, all the LCD segments are
displayed for 1 second, then the percent indication of the remaining battery life is shown for another second (E.g. % 100 BATT). The meter then
enters the normal measuring mode.
Note: If the display needs to be checked, keep the
ON button pressed while turning the meter on.
The meter will display all segments as long as
the button is pressed.
To freeze the display
While in measurement mode, press the SET/
HOLD button, HOLD appears on the secondary
display and the reading will be frozen on the LCD
(E.g. pH 5.73 HOLD). Press any button to return
to normal mode.
To turn the meter OFF
While in normal measurement mode, press the
ON/OFF/MODE button. OFF will appear on the
secondary display. Release the button.
Note: The meter is provided with an acoustic sig-
nal feature, which can be disabled using the
switch located in the battery compartment.
Note: When the meter detects the absence of a
temperature probe at its input, the Automatic
Temperature Compensation is turned off, and
the meter uses a default value of 25°C (77°F)
for the temperature measurement and compensation. In this condition, the secondary LCD
shows 25.0°C (77.0°F) blinking. When a probe
is connected, the meter automatically returns
to the ATC mode, the A TC t ag is turned on, and
the temperature is shown on the secondary
display.
Note: To clean the meter, do not use aggressive
detergents. It is recommended to use water.
pH MEASUREMENT & CALIBRATION
• Make sure the meter has been calibrated before use.
• If the probe is dry, soak it in HI 70300 storage
solution for one hour to reactivate it.
• Place the tip of the probe on the sample to be
tested and wait until the symbol on the top
left of the LCD is turned off.
• The LCD shows the pH value (automatically
compensated for temperature) on the primary
LCD, while the secondary LCD shows the temperature of the solution.
• After each measurement, it is recommended
to perform a complete cleaning of the probe:
use the suitable Cleaning solutions (see "Accessories" section) and clean the probe tip
thoroughly to eliminate dirtiness and avoid
cross-contamination.
• When not in use, switch the meter OFF and
clean the probe with the specific Cleaning so-
lutions (see "Accessories" section) before storing it.
pH calibration
For better accuracy, frequent calibration of the
instrument is recommended. In addition, the
instrument 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.
• From normal mode, press and hold the ON/
OFF/MODE button until OFF on the secondary
display is replaced by CAL. Release the button.
• The LCD enters the calibration mode, displaying “pH 7.01 USE” (or “pH 6.86 USE” if the
NIST buffer set was selected). After 1 second
the meter activates the automatic buffer recognition feature. If a valid buffer is detected, then
its value is shown on the primary display, and
REC appears on the secondary LCD. If no valid
buffer is detected, the meter keeps the USE
indication active for 12 seconds, and then replaces it with WRNG , indicating that the sample
being measured is not a valid buffer.

accepts the calibration when the reading is
stable; the meter will show on the primary display the accepted buffer , with the message “OK
1” on the secondary display, and an audible
signal is produced. After 1 second the meter
automatically returns to the normal measuring mode.
If a single-point calibration with buffers pH 7.01
or 6.86 is desired, then after the calibration point
has been accepted the ON/OFF/MODE button
must be pressed in order to return to the normal measuring mode. After the button is
pressed, the meter shows "7.01" (or "6.86") "OK 1", and an audible signal is produced. After 1 second, the meter automatically returns
to the normal measuring mode.

point has been accepted, the “pH 4.01 USE”
message appears. The message is held for
12 seconds, unless a valid buffer is recognized. If no valid buffer is recognized, then the
WRNG message is shown. If a valid buffer (pH
4.01, pH 10.01 or pH 9.18) is detected, then
the meter completes the calibration procedure.
When the buffer is accepted, the LCD shows
the accepted value with the “OK 2” message
on the secondary display. The meter then returns to the normal measuring mode.

To quit calibration and to reset to the default values
• After entering the calibration mode and before
the first 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 secondary LCD displays ESC for 1 second and the meter returns to normal mode.
• T o reset to the default values and clear a previous calibration, press the SET/HOLD button
after entering the calibration mode and before
the first point is accepted.
The secondary LCD displays CLR for 1 second, the meter resets to the default calibration
and the “CAL” tag on the LCD disappears.
METER SETUP
Setup mode allows the selection of the temperature unit and of the pH buffer set.
T o enter the Setup mode, press and hold the ON/
OFF/MODE button until CAL on the secondary
display is replaced by TEMP and the current temperature unit (E.g. TEMP °C). Then:

to change the calibration buffer set
ting the temperature unit, the meter will show
the current buffer set: “pH 7.01 BUFF” (for 4.01/
7.01/10.01) or “pH 6.86 BUFF” (for 4.01/6.86/
9.18). Change the set with the SET/HOLD button, then press ON/OFF/MODE to return to normal mode.

BATTERY REPLACEMENT
The meter displays the remaining battery percentage when turned on. When the level is
below 5%, the symbol on the bottom left
of 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.
Unscrew the 4 screws located on the back of
the meter and carefully replace the 3 AA batteries located in the battery compartment,
while paying attention to their polarity. Reattach the back making sure that the gasket is
in place and tighten the 4 screws to ensure a
watertight seal.
