should be taken.
9. Do not use or store the meter in an environment of
high temperature and humidity. The performance of
the meter may deteriorate after dampened.
10. The internal circuit of the meter shall not be
altered at will to avoid damage of the meter and any
accident.
11. Soft cloth and mild detergent should be used to
clean the surface of the meter when servicing. No
abrasive and solvent should be used to prevent the
surface of the meter from corrosion, damage and
accident.
