One-point calibration:
One point calibration that is to calibrate EO with one standard buffer, the default
slope is 100%.
Note: The meter will delete last data auto after done one point calibration. The
default slope is 100% after one point calibration.
f) Insert PH electrode which has been cleaned with distilled water into pH7.00
standard buffer solution in the state of measurement. Press “Std” button once, the
screen will display “Std yes”. Press “Enter” button to enter calibration state, press
any button to exit and return the measuring state.
Enter the calibrating state, the meter recognizes the buffer automatically and
displays the pH value of standard buffer solution at this temperature. When the
value is stable, press "Enter" button, displays the slope and E0 and return the
measuring state, if want to stop the calibration, press “pH / mV” button to exit.
Two-point calibration:
g) Prepare two standard buffer solutions. Insert the electrode which has been cleaned
with distilled water into pH4.00, press “Std” button once, the screen will display “Std
yes”. Press “Enter” button to enter calibration state, press any button to exit and
return the measuring state.
Enter the calibrating state, the meter recognizes the buffer automatically and
displays the pH value of standard buffer solution at this temperature. When the
value is stable, press "Enter" button to finish and return the measuring state.
Insert the electrode which has been cleaned with distilled water into pH10.01, press
“Slope” button once, the screen will display “Std yes”. Press “Enter” button to enter
calibration state, press any button to exit and return the measuring state.
Enter the calibrating state, the meter recognizes the buffer automatically and
displays the pH value of standard buffer solution at this temperature. When the
value is stable, press "Enter" button to finish and return the measuring state.
