This instrument can be used for measurement under class I.
Warning:
This instrument is only allowed to be used in the specified measurement class.
Measurement class definition
⚫
Class I refers to measurements taken on a circuit not directly connected to
the main power supply.
For example, measurements made on circuits that are not
exported from a main power supply, especially from a protected (internal) main
power supply. In the latter case, the instantaneous stress will change. Therefore,
the user should understand the instantaneous capacity of the instrument.
⚫
Class II refers to measurements taken on a circuit directly connected to
low-voltage instruments.
For example, measurements made on household
appliances, portable tools, and similar equipment.
⚫
Class III refers to measurements taken on construction equipment.
For
example, measurements made on switchboards, circuit breakers, circuits (including
cables, busbars, junction boxes, switches, sockets) in fixed equipment, as well as
equipment for industrial use and certain other equipment (for example, fixed motors
permanently connected to fixed instruments).
⚫
Class IV refers to measurements taken at the source of low-voltage
equipment.
For example, measurements made on electricity meters, primary
overcurrent protection equipment, and pulse control units.
