7. Rinse the electrode with deionised water or in
rinse solution, and place it in the next pH buffer.
8. Follow steps 5 to 8 for additional calibration
points. See Figure 7.
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. See Figure 8.

To limit the number of pH buffer values available during
calibration, see Setup Section 8.4 P3.2: Selecting
number of pH calibration points
on page 34.
