indicate the pH standard buffer solution.
5 Wait for the measured pH value to stabilize.
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 deionised
water or in rinse solution, and place it
in the next pH buffer.
8 Follow Steps 5 to 8 for additional
calibration points.
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.
