6. Press ENTER to confirm calibration. The meter is
now calibrated to the current buffer. The lower
display scrolls through the remaining buffer
options.
•
If you are performing multi-point calibration,
go to step 7.
•
If you are performing one-point calibration, go
to step 9.
7. Rinse the electrode with de-ionized 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 6.
9. When calibration is complete, press CAL/MEAS to
return to pH measurement mode.
NOTES: 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. Figure 7.
To limit the number of pH buffer values available during
calibration, see SETUP section P3.2 on page 30.
