Hantek — 1.5 Maintenance and cleaning

Safety requirem ents EN Installation (Overvoltage) Class This product is powered by a mains supply conforming to Installation (overvoltage) Class II. Warning: Ensure that no overvoltage (e.g. from lightning) reaches the product. Otherwise, the operator may be in danger of receiving electric shock. Installation (overvoltage) class definition Installation (overvoltage) Class I refers to the signal level applicable to the device measurement terminals connected to the source circuit where measures have been taken to limit the instantaneous voltage to the corresponding low level.

Installed (overvoltage) Class II refers to the local distribution level for equipment connected to a mains (AC supply). The degree of pollution 2 class Definition of pollution level ⚫ Pollution degree 1: no pollution, or only dry non-conductive pollution. This pollution level has no impact. For example: clean room or air-conditioned office environment. ⚫ Pollution level 2: generally only dry non-conductive pollution occurs. Transient conduction due to condensation may sometimes occur. For example: general indoor environment. ⚫ Pollution level 3: conductive pollution occurs, or dry non-conductive pollution becomes conductive by condensation. For example, an outdoor environment with a canopy.

⚫ Pollution level 4: Permanent conductive pollution through conductive dust, rain, or snow. For example: outdoor places.
