11. For 2 or 3 point calibration, start with pH 7,
then repeat the above steps for pH 4 and/or
pH 10.
12. For the most accurate readings, the
temperature of the sample and cliabration
solutions should be similar.
13. Repeat the above procedures until
readings stabilize.
14. NOTE: If the buffer needs to be adjusted, press
▲ to adjust the displayed value. “SA” (save) is
