Note

: Direct sunlight, radiators, and other heat sources should be taken

into account when assessing the ambient temperature.

WARNING: Do not operate the oscilloscope in an explosive
atmosphere or wet and damp conditions.

The design of the instrument has been verified to conform to EN 61010-1

safety standard per the following limits:



Installation (overvoltage) Category: II (Mains Supply Connector)



Degree of Pollution: II



Degree of Protection: IP20

Note

Installation (Overvoltage) Category II refers to the local distribution level,

which is applicable to equipment connected to the mains supply (AC

power source).

Degree of Pollution II refers to a working environment which is dry and

non-conductive pollution occurs. Occasional temporary conductivity

caused by condensation is expected.

CAUTION: Protect the display touch screen of the scope from
excessive impact.
