When using the instrument, check that wires are connected properly. If neglected, correct
measurement cannot be obtained and it may cause malfunction in the instrument or cause damage
to peripheral devices or a critical accident.
Caution
Do not give the instrument such a shock as throwing something at it. It may cause damage or
destroy electrical circuits and even have loose resistance to environment or operability.
Caution
Do not remove the cover of the case of the instrument, nor peel off the panel sheet nor take the
instrument into pieces. If neglected, it may cause damage to the case and the panel sheet and even
have the possibility of damage to resist to environments or operational performances.
