OPERATIONAL GUIDE
• pH reading with the selected resolution.
• Temperature reading in the selected unit (°C or °F).
• Electrode condition during the calibration day.
• The buffers used in last pH calibration (if feature is enabled in SETUP).
• Battery level indicator.
• Available functional keys.
In order to take more accurate pH measurements, make sure that the instrument is calibrated (see
page 11 for calibration details).
It is recommended that the electrode is always kept moist and rinsed thoroughly with the sample to
be measured before use.
The pH reading is directly affected by temperature. For accurate pH measurements, temperature
must be taken into consideration. If the sample temperature is different from the temperature at
which the pH electrode was kept, allow a few minutes to reach thermal equilibrium.
On the pH screen are displayed:
TEMPERATURE MEASUREMENTS
For HI98163 the temperature sensor is connected through DIN socket.
Note: The temperature can be displayed in Celsius degrees (°C) or in Fahrenheit degrees
(°F) (see SETUP for details, page 23).
BACKLIGHT FEATURE
The instrument is provided with a Backlight feature, which can be easily toggled on and off through
the keyboard by pressing LIGHT.
Note: The backlight automatically shuts off after a set period (see SETUP for details,
page 23) with no buttons pressed.

pH CALIBRATION
It is recommended to calibrate the instrument frequently, especially if high accuracy is required.
The pH range should be recalibrated:
• Whenever the pH electrode is replaced.
• At least once a week.
• After testing aggressive chemicals.
• When calibration alarm time out is expired ‑ “CAL DUE” blinks (if feature is enabled in
SETUP).
• If “Outside Cal Range” message blinks during pH measurement (the measurement range is
not covered by current calibration, if feature is enabled in SETUP).
PROCEDURE
HI98163 instrument offers a choice of seven standard buffers (pH 1.68, 4.01, 6.86, 7.01, 9.18, 10.01
and 12.45). The meter allow the user to set up to five custom buffers. The set custom buffers are the
buffer values at 25 °C.
When a custom buffer is selected during calibration, the Custom functional key is displayed on the
LCD. Press Custom key in order to enter custom buffer changing mode. Use / keys to change
the value in a ±1.00 pH window, in according with the temperature reading and then Accept. Press
ESC to leave custom buffers value unchanged.
For accurate pH measurements, it is recommended to perform a calibration with buffers that bracket
the expected pH value. At least two point calibration is recommended.
The instrument will automatically skip the buffers used during calibration and the buffers which are
in a ±0.2 pH window around one of the calibrated buffers.
• Remove protective cap and rinse the electrode with distilled or deionized water.
• Pour small quantities of selected buffer solutions into clean beakers. For accurate calibration use
two beakers for each buffer solution, the first one for rinsing the electrode and the second one
for calibration.

FOUR, THREE, TWO or ONE POINT CALIBRATION
• Proceed as described in “FIVE POINT CALIBRATION” section.
• Press CAL or ESC after the appropriate accepted calibration point. The instruments will return to
measurement mode and will memorize the calibration data.
FIRST POINT MODE
Two SETUP options are available to determine how the previous calibration will be affected by a
subsequent one point calibration. These options are Replace or Offset.
If the Replace option is selected, the slopes between current buffer and nearest lower and higher
buffers will be recalculated.
If the Offset option is selected, an electrode offset correction is performed keeping unchanged the
existing slopes.
ERROR SCREENS
Wrong buffer
The calibration cannot be confirmed.
The pH reading is not within range of the selected buffer. Select another buffer using the / keys
or change the buffer.
pH CALIBRATION
Electrode Dirty/Broken alternatively with Buffer Contaminated
The calibration cannot be confirmed.
The offset of the electrode is not in the accepted range. Check if the electrode is broken or clean it
following the Cleaning Procedure (see page 45). Check the quality of the buffer. If necessary, change
the buffer.

17
pH CALIBRATION
Wrong slope
The calibration cannot be confirmed.
The evaluated slope is less than the lowest accepted value (80% of default slope).
The evaluated slope is more than the highest accepted value (110 % of default slope).
Wrong old slope
An inconsistency between new and previous (old) calibration is detected. Clear old calibration
parameters and proceed with the calibration from the current point. The instrument will keep all
confirmed values during current calibration.
Note: For one point calibration the electrode condition is not displayed in the measurement
screen. Each time a buffer is confirmed, the new calibration parameters replace the old
calibration parameters of the corresponding buffer.

18
pH CALIBRATION
If the current confirmed buffer has no correspondence in the existing stored calibration and this is
not full, the current buffer is added to the existing stored calibration.
If the existing stored calibration is full (five calibration points), after confirming the calibration point,
the instrument will ask which buffer will be replaced by current buffer.
Press / keys to select another buffer to be replaced.
Press CFM to confirm the buffer that will be replaced.
Press CAL or ESC to leave replace mode. In this case, the buffer will not be memorized.
Note: The replaced buffer is not removed from calibration list and it can be selected for the
next calibration points.
WORKING WITH CUSTOM BUFFERS
If at least one custom buffer was set in SETUP menu, it can be selected for calibration by pressing
the / keys. The Custom functional key will be displayed.
Press Custom if you want to adjust the buffer value according with current temperature.
Use the / keys to change the buffer value.
Press Accept to accept new value or ESC to exit changing mode.
Note: Custom buffer value can be adjusted in a ±1.00 pH window, around the set value.

19

WORKING WITH MILI pH BUFFERS
If calibration is invoked from mili pH range, the calibration buffer can be modified in a ±0.020 pH
range in according with the label on the calibration buffer.
Press Change to enter buffer adjust mode.
Use / keys to change the buffer value.
Press Accept to accept new value or ESC to exit adjusting mode.
CLEAR CALIBRATION
Press Clear functional key when displayed to clear old calibrations.
All old calibrations, are cleared and the instrument continues calibration. The points confirmed in
current calibration are kept.
Note: If Clear calibration is invoked during the first calibration point, the instrument returns
to measurement mode.

20
pH CALIBRATION
CLEAN ELECTRODE WARNING
Each time pH calibration is performed, the instrument internally compares the new calibration with
the one previously stored.
When this comparison indicates a significant difference, the “Clean Electrode” warning message is
displayed to advise the user that the pH electrode may need to be cleaned (see ELECTRODE
CONDITIONING AND MAINTENANCE section for details, page 44).
After cleaning, perform a new calibration.
Note: If the calibration data are cleared, the comparison is done with the default values.
ELECTRODE CONDITION
The display is provided with an icon, and a numeric value (unless the feature is disabled) which gives
an indication of the electrode status after calibration.
The “condition” remains active until the end of the calibration day.
Note: The electrode condition is evaluated only if current calibration includes at least two
standard buffers.
