10. Applied voltage switch
Opening the cover will activate this switch to turn applied voltage OFF for safety.
The applied voltage switch has mechanical durability of 250,000 times operation.
However, after it reaches the end of its service life, it will be always OFF regardless
of opening and closing of the cover.
11. Lock
Be sure to close and lock the cover before starting measurement. If measurement is per-
formed without locking it, a sample does not stick fast to the electrodes and correct meas-
ured values cannot be obtained.
