Soak the electrode in the first
solution for calibration prepared in
step 3.
Place the electrode fully into the solution for
calibration so that the solution comes up to the
liquid junction.

Do not touch the stir bar with the electrode. It may
damage the electrode.

Make sure that the rubber
stopper of the internal solution
fill port is open during
calibration.
If it is closed, the internal
solution does not ooze out very
much from the liquid junction.
As a result, the potential of the reference electrode will
become unstable and susceptible to stir.
It is recommended to place the electrode in the electrode stand.
