Step 2 - Place the pH electrode and temperature probe in the
high buffer solution (here pH 7) and turn on stirring of the
high buffer solution. When the relative pH output in the blue
line is stable, go to NEXT STEP.
Step 3 - Place the pH electrode and temperature probe in the
low buffer solution (here pH 4) and turn on stirring of the low
buffer solution. When the relative pH output in the blue line
is stable, go to NEXT STEP.
Step 4 - The calibration is now finished. The values in the two
bottom lines are the actual pH and temperature reading.
