49SPECIFICATIONS AND PERFORMANCE
SYSTEM CLASSIFICATION
• Type of protection against electric shocks: Class Ι equipmentClass Ι equipment does not depend on basic insulation only for protection against electricshocks. It can also be earthed; therefore, the metal parts with which one comes into contactdo not become conductive if the basic insulation fails.
• Degree of protection against harmful ingress of water: IPx0DC-1 has no protection against ingress of water. (The degree of protection against harmfulingress of water defined in IEC 60529 is IPx0)
• Classification according to the methods of sterilization or disinfection recommended by themanufacture: not applicable.
DC-1 has no part to be sterilized or be disinfected.• Methods of sterilization or disinfection recommended by the manufacturer: DC-1 do not have
any part to be sterilized or disinfected.• Classification according to the degree of safety of application in the presence of a flammable
anaesthetic mixture with air or with oxygen or nitrous oxide: Equipment not suitable for use inthe presence of a flammable anaesthetic mixture with air or with oxygen or nitrous oxide.DC-1 should be used in environments where no flammable anesthetics and/or flammable gasesare presents.
• Classification according to the mode of operation: Continuous operation.• Continuos operation is the operation under normal load for an unlimited period, without the
specified limits of temperature being exceeded.
PURPOSES OF USE
• This instrument is used for the enlargement observation of eyeballs and the parts.
OPERATION PRINCIPLES
• This instrument is combined with the slit lamp and used to take pictures and records ofobserved images.
