[. . . ] · If the probe has been left dry, soak in a storage or pH 7 solution at least for one hour to reactivate it. · Select the pH mode with the SET/HOLD button. · Submerge the probe in the sample to be tested while stirring it gently. Wait until the stability symbol on the top left of the LCD disappears. · The pH value automatically compensated for temperature is shown on the primary LCD while the secondary LCD shows the temperature of the sample. · If measurements are taken in different samples successively, rinse the probe tip thoroughly to eliminate crosscontamination; and after cleaning, rinse the probe tip with some of the sample to be measured. Calibration buffer set · While in pH measurement mode, press and hold the MODE button until TEMP and the current temperature unit are displayed on the lower LCD. · Press the MODE button again to show the current buffer set: pH 7. 01 BUFF (for 4. 01/7. 01/10. 01) or pH 6. 86 BUFF (for 4. 01/6. 86/9. 18). · Press the SET/HOLD button to change the buffer set. · Press the MODE button to return to normal pH measurement mode. pH calibration · While in pH measurement mode, press and hold the MODE button until CAL is displayed on the lower LCD. The LCD will display pH 7. 01 USE or pH 6. 86 USE (if you have selected the NIST buffer set). · For a single point pH calibration, place the probe in any buffer from the selected buffer set (eg. The meter will automatically recognize the buffer value. If using pH 7. 01 (or 6. 86 from the NIST buffer set), after recognition of the buffer press the MODE button to return to the pH measurement mode. · For a two point pH calibration, place the probe in pH 7. 01 (or 6. 86, if you have selected the NIST buffer set). The meter will recognize the buffer value and then display pH 4. 01 USE. Stabilty indicator Battery percentage Low battery indicator AT C Place the probe in the second buffer (pH 4. 01 or 10. 01, or, if using NIST, pH 4. 01 or 9. 18). [. . . ] · Press the MODE button to show the current temperature compensation ß. · Press the SET/HOLD button to change the temperature compensation ß. · Press the MODE button return to normal operation. EC calibration · While in the EC measurement mode, press and hold the MODE button until CAL is displayed on the lower LCD. [. . . ]
