calibrating the instrument.

• Performing pH measurement

• In measure mode, press the button
• Connect the electrode to the BNC of the instrument in green colour.
Connect the temperature probe to the RCA in the green input.
•
• If the user does not use an electrode with a built-in temperature probe or an external probe NTC 30KΩ,
it is recommended to manually update the temperature value (MTC).
• Remove the electrode from its tube, rinse with distilled water and dab gently with paper towel.
• Check the presence and eliminate any air bubbles in the membrane bulb by stirring vertically (as for
the clinical thermometer). If present, open the side cap.
• Dip the electrode in the sample, while keeping it slightly stirred.
• Consider the measurement truthful only when the stability icon
