Safety requirement CN To avoid the risk of short circuits or electric shock inside the instrument, do not operate the instrument in a damp environment. Altitude Operating and Non-operating: 2,000m. This product is powered by mains conforming to installation (overvoltage) category 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) Category Definitions.
Installation (overvoltage) category I refers to the signal level, which is suitable for measuring terminals connected to equipment in the source circuit, where measures have been taken to limit instantaneous voltage to the corresponding low level. Installation (overvoltage) category II refers to the local distribution level, which is suitable for equipment connected to the mains (AC power supply).

conditioned office environment. Temporary conductivity caused by condensation is to be expected. For example, indoor environment. ⚫ Pollution Degree 3: Conductive pollution or dry nonconductive pollution that becomes conductive due to condensation occurs. To be found in industrial environment or construction sites (harsh environments). For example, sheltered outdoor environment. ⚫ Pollution Degree 4: The pollution generates persistent conductivity caused by conductive dust, rain, or snow. For example, outdoor areas.
