CAT I Measuring category I for measurements at electrical and electronic devices that are not directly supplied

with mains voltage (e.g. battery-powered devices, protective low voltages, signal and control voltages,

etc.)

CAT II Measuring category II for measurements at electrical and electronic devices connected to the mains

supply directly with a mains plug. This category also covers all lower categories (e.g. CAT I for measuring

signal and control voltages).

CAT III Measuring category III for measuring in building installation (e.g. outlets or sub-distribution). This category

also covers all lower categories (e.g. CAT II for measuring electronic devices). Measuring operation in

CAT III is only permitted with measuring prods with a maximum free contact length of 4 mm or with cover

caps above the measuring prods.

CAT IV Measuring category IV for measurements at the source of the low-voltage installation (e.g. main distribu-

tion, building handover points of the energy suppliers, etc.), and outdoors (e.g. work at earthing cable,

outdoor line, etc.). This category also contains all lower categories. Measuring operation in CAT IV is only

For safety and approval reasons, unauthorised conversion and/or modication of the device are not permitted.

Consult an expert when in doubt as to the operation, safety or the connection of the device.

Meters and accessories are not toys and have no place in the hands of children!

In commercial institutions, the accident prevention regulations of the Employer’s Liability Insurance Association for

Electrical Systems and Operating Materials are to be observed.

In schools, training centres, computer and self-help workshops, handling of meters must be supervised by trained

personnel in a responsible manner.

Ensure before every measurement that the meter is not set to another measuring range. Also observe that the

HOLD button has not been pushed at the beginning of the measurement (display with the HOLD button pushed:

“H”). If the HOLD function is activated before commencement of the measurement, no measured value is displayed!
