Measurement Category
The DS1000CA series Digital Oscilloscope is intended to be used for measurements in
Measurement Category I.
Measurement Category Definitions
Measurement Category I is for measurements performed on circuits not directly
connected to MAINS. Examples are measurements on circuits not derived from MAINS,
and specially protected (internal) MAINS derived circuits. In the latter case, transient
stresses are variable; for that reason, the transient withstand capability of the
equipment is made known to the user.
