1-Point Calibration (Calibration Mode: Manual) - Optex SE-pH-D Instruction Manual

1-point calibration (Calibration mode: Manual)

Perform calibration with the pH standard solution set in step 4 of "Calibration
standard selection" P.18.
・ The 1-point calibration is for pH measurement. It does not affect
ORP measurement.
Caution
・ In 1-point calibration, span errors can be minimized by using
a calibration solution (standard solution) that is close to the
expected pH value of the measurement water.
Clean the sensor body and electrode surface.

pH for the 1st calibration solution (standard solution) and immerse
the sensor.
Allow the sensor to settle to the temperature of the calibration
3
solution (standard solution) for about 5 minutes with little change
in temperature, then check that there are no bubbles on the
electrode surface.
