Measurement category definition
Measurement category I
Refers to measurements on circuits that are not directly connected to the mains. For
example, make measurements on circuits that are not derived from a main power
source, especially those that are protected (internal). In the latter case, the transient
stress changes. Therefore, users should understand the instantaneous ability of the
device.
Measurement category II
Refers to measurements made on circuits directly connected to low-voltage equipment.
For example, make measurements on home appliances, portable tools, and similar de-
vices.
Measurement category III
Refers to measurements in construction equipment. For example, power distribution
boards, circuit breakers, wiring (including cables, bus bars, junction boxes, switches,
sockets) in fixed equipment, and equipment for industrial use and certain other equip-
ment (for example, fixed motors permanently connected to fixed equipment) Take
measurements.
