5. Operation 5.3 Measuring Setting up the instrument If large quantities of the electrolyte gel are stuck to the probe when removed from the storage cap, it is a sign that the gel is spent. A new storage cap is needed. Clean off the pH probe before and after each measurement with low concentration soap water followed by tap water (water temperature should be below 40 °C). -
Page 11: Calibrating Instrument
The instrument is switched on and is in the measurement mode. 1 Open calibration mode: - testo 206-pH3 with pH probe without temperature sensor: The set temperature value for manual temperature compensation is displayed for 2s. The value must correspond to the temperature of the buffer solution. - Page 12 5. Operation 2 Skip calibration point: MODE -o o r- Immerse probe in the buffer solution and start calibration: - The instrument waites for a stable reading : AUTO flashes. - If a stable reading is available (change less than 0.02pH in 20s), the calibration point calibrates and the instrument changes to the next calibration point (if available) or to the gradient and offset value display.
