• If you are performing one-point calibration, go to step 9.
7. Rinse the electrode with de-ionised water or rinse solution, and
place it in the next pH buffer.
8. Follow steps 5 to 7 for additional calibration points.
9. When calibration is complete, press CAL/MEAS to return to pH
measurement mode.
NOTE: To exit from pH calibration mode without confirming calibration,
DO NOT press ENTER in step 6. Press CAL/MEAS instead.
If the selected buffer value is not within ±1.0 pH from the measured pH
value: the electrode and buffer icon blink and the ERR annunciator
appears in the lower left corner of the display.
To limit the number of pH buffer values available during calibration,
see section 8.4 Setup P3.2 on page 29.
