• Immerse the temperature probe in the second vessel as near as possible to the reference
thermometer. Allow a few seconds for the probe to stabilize.
• Use the ARROW keys to set the calibration point value to that of the hot water, measured by
the reference thermometer.
• The (unstable measurement) symbol will be shown on the display until the reading
becomes stable.
• When the reading is stable and close to the selected calibration point, the (unstable
measurement) symbol will disappear and the Confirm key will become active.
• Press Confirm to confirm the calibration point. The instrument will return to the pH meter/
titrator main screen.
Notes:• If the reading is not close to the selected calibration point, the “Wrong” message will
be displayed. Change the temperature probe and restart the calibration.
• If the temperature probe is disconnected or the measured temperature is out of the -
20 to120 °C range the instrument will display “----”. The calibration point value can
be changed using the ARROW keys.
