Measurement Category
The 6000 Series 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.
Measurement category II is for measurements performed on
circuits directly connected to the low voltage installation.
Examples are measurements on household appliances, portable
tools and similar equipment.
Measurement category III is for measurements performed in the
building installation. Examples are measurements on
distribution boards, circuit-breakers, wiring, including cables,
bus-bars, junction boxes, switches, socket-outlets in the fixed
installation, and equipment for industrial use and some other
equipment, for example, stationary motors with permanent
connection to the fixed installation.
Measurement category IV is for measurements performed at the
source of the low-voltage installation. Examples are electricity
meters and measurements on primary overcurrent protection
devices and ripple control units.
