OPERATIONAL GUIDE
INITIAL PREPARATION
The instrument is supplied complete with 1.5V AA (4 pcs.) batteries. For placing the batteries inside the meter, see page 42. Make sure that the protective micro USB cover is used when not connected to a computer to ensure waterproof protection. For HI98163 connect the pH/temperature electrode to the DIN connector. Turn the instrument ON by pressing ON/OFF key.
At start‑up the display will show the Hanna logo for a few seconds followed by the percentage indication of the remaining battery life, then enters the measurement mode. After measurement switch the instrument off, clean the electrode and store it with a few drops of
HI70300 storage solution in the protective cap (see page 45).
The Auto Power Off feature turns the instrument off after a set period (default 30 min) with no button pressed to save battery life. To set another period or to disable this feature, see SETUP menu on page 23. The Auto Light Off backlight feature turns the backlight off after a set period (default 1 min) with no buttons pressed. To set another period or to disable this feature, see SETUP menu on page 23.
pH MEASUREMENTS
To take a pH measurement remove the electrode protective cap and simply submerge the tip of the electrode (4 cm/1½") into the sample to be tested. Press RANGE key to choose between pH and mV ranges. Use MODE key to select the pH resolution. Allow time for the electrode to adjust and reading to stabilize (hourglass symbol turns off).

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.
