Many air bubbles adhered!

To reduce the air bubbles, stir the
electrode completely and better to 
dip the electrode into solution at 
oblique angle.  To dip the electrode 
at vertical angle is easy to create 
many air bubbles. 

After soaking the electrode in 
solution for 15~30 minutes, inspect
the electrode carefully to make sure
no bubbles adhere. If air bubbles
still exist, tap the bottom of the 
container gently and stir the electrode
to remove the air bubbles. If above 
method are not working, remove
the electrode out of solution and 
blow at the electrode to remove the 
air bubbles.
