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 low-
voltage 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 MTX 20x 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).
