With regard to multimeters and test instruments, the CE declaration of conformity confirms that Eu- ropean regulations (low-voltage directive and EMC directive) are adhered to.The CE declaration is a prerequisite for putting products into circulation within the European Community. Adherence is substantiated by fulfilling the following standards: IEC 61010-1 (international), EN 61010-1 (German version) and VDE classification VDE 0411-1.
Safety requirements for electrical equipment for measurement, control and laboratory use are de- scribed in this standard.
Currently valid safety regulations include:
 IEC 61010-1:2010 + Cor.:2011  DIN EN 61010-1:2010  VDE 0411-1:2011
CAT Description Applications
CAT I (0)* Measurements in electrical circuits which are not directly connected to the mains
e.g. batteries etc.
CAT II Measurements in electrical circuits which are directly connected to the low-voltage mains
via plug, e.g. in household, office and laboratory applications
CAT III Measurements in building installations Stationary consumers, distributor terminals, devices connected permanently to the distributor
CAT IV Measurements at power sources for low-voltage installations

MULTIMETERS
 A multimeter is an electronic measuring instrument that combines several mea- surement functions into a single unit, and is used primarily to measure electrical quantities. To measure means to compare a known quantity with an unknown quantity. The stan- dards of measure of the PTB in Brunswick (German Federal Institute of Physics and Metrology) are used as comparative quantities
for our multimeters This is confirmed by means of a DAkkS calibration certificate. Multimeters included in the METRAHIT series are rugged, reliable digital multimeters with housings made of impact resistant plastic, and are equipped with unique, patented automatic blocking sockets (ABS). The devices feature a new design and are equipped with state-of- the-art technology and safety.

Selecting the Right Digital Multimeter (DMM)
The icons help provide the user with quick, condensed information regarding the range of appli- cations and the functions of the respective DMM, thus assuring correct selection.
Important selection criteria include:  Number of displayed digits in digits
 Range of application, e.g. CAT III,
and max. permissible voltage, e.g. 1000 V
 Measuring accuracy
measurement
or via current transformers or current sensors
 Integrated data memory and the interface for data
transfer for analysis at a PC
 Special device functions such as milliohm mea-
surement by means of 4-wire measurement, as
well as insulation, power and energy measure-
ment, calibration functions, intrinsic safety etc.
