1.1.2 Measurement categories

CAT II: Test and measurement circuits directly connected to points of use (power
outlets and other similar points) on the low voltage network.
E.g. Measurement on circuits in network for household appliances, portable tools and
other similar instruments.
CAT III: Test and measurement circuits connected to parts of the building's low
voltage network installation.
E.g. Measurement on distribution switchboards (including secondary meters), the
circuit breakers, cabling including cables, busbars, junction boxes, circuit breakers,
power outlets in the fixed installation and industrial instruments and other equipment
such as motors permanently connected to the fixed installation
CAT IV: Test and measurement circuits connected to the source of the building's
lowvoltage network installation.
E.g. Measurement on equipment installed upstream of the main fuse or building
installation cut-off switch.
The multimeters conform CATIII 600V, acc. to IEC 61010-1 - Ed. 2.

2. INSTRUMENT OVERVIEW

2.1 Introduction
The digital multimeter is an instrument for measuring electrical and physical
quantities that groups the following functions:
• AC or DC voltage measurement,
• AC or DC current measurement,
• resistance measurement,
• continuity measurement with beeper,
• diode test,
• capacitance measurement,
• temperature measurements.
A NCV indication detects a voltage 230V (50Hz).
