CAT I
Installation (Overvoltage) Category rating per EN 61010-1 safety 
standard and is applicable for the oscilloscope front panel measuring 
terminals. CAT I rated terminals must only be connected to source 
circuits in which measures are taken to limit transient voltages to an 
appropriately low level. 
Operating Environment
The instrument is intended for indoor use 
and should be operated in a clean, dry 
environment. 
Note: Direct sunlight, radiators, and other 
heat sources should be taken into account 
when assessing the ambient temperature. 
WARNING
The scope must not be operated in 
explosive, dusty, or wet/damp 
atmospheres. 
The design of the instrument has been 
verified to conform to EN 61010-1 safety 
standard per the following limits: 
 
Installation (Overvoltage) Categories II 
(Mains Supply Connector) & I (Measuring 
Terminals) 
 
Pollution Degree 2 
 
Protection Class I 
Note: 
 
Installation (Overvoltage) Category II refers 
to local distribution level, which is applicable 
to equipment connected to the mains supply 
(AC power source). 
 
Installation (Overvoltage) Category I refers 
to signal level, which is applicable to 
equipment measuring terminals that are 
connected to source circuits in which 
measures are taken to limit transient 
voltages to an appropriately low level. 
 
Pollution Degree 2 refers to an operating 
environment where normally only dry non-
conductive pollution occurs. Occasionally a
