PROBE CALIBRATION
Calibrate routinely before use, if the readings seem erratic, and
whenever the batteries are replaced. For the highest accuracy, we
recommend a two point calibration. If only calibrating at a single
point, make certain that the buffer value is close to the sample that
will be measured and the buffer temperature remains stable.
1. Press
POWER
to turn the meter on and press
MODE
to select
“pH” mode. “pH” appears on the LCD.
2. Select the calibration buffer type:
N.I.S.T.
or
CUSTOM
(see page 14).
Note…
pH 4 may be calibrated using either the N.I.S.T.(recommended
option) or CUSTOM buffer. pH 7 and pH 10 require the CUSTOM
buffer. (See SETUP MODE on page 14.)
3. Rinse the probe in de-ionized water or rinse solution. DO NOT
wipe the pH probe dry. Wiping the probe may cause static and
cause calibration and measurement instability.
4. Select the pH buffer and pour enough solution to totally immerse
the probe tip into a clean container.
5. Dip the probe into the container, immersing the probe tip.
6. Stir the probe gently to create a uniform sample.
