II. CENELEC DIRECTIVES :

The  instruments  conform  to  CENELEC  Low-voltage  directive
2014/35/EC, Electromagnetic compatibility directive 2014/30/EU &
RoHS directive 2011/65/EU.

Measurement Category

Measurement Category IV

 is applicable to test & measuring circuits

connected  at  the  source  of  the  building’s  low-voltage  MAINS 
installation.  Examples are measurements on devices installed before
the main fuse or circuit breaker in the building installation.

Measurement Category III

 is applicable to test & measuring circuits

connected to the distribution part of the building’s low-voltage MAINS
installation.    Examples  are  measurements  on  distribution  boards
(including  secondary  meters),  circuit-breakers,  wiring,  including 
cables, bus-bars, junction boxes, switches, socket-outlets in the  fixed
installation,  &  equipment  for  industrial  use  &  some  other  equipment 
such  as  stationary  motors  with  permanent  connection  to  the 
fixed installation

Measurement Category II

 is applicable to test & measuring circuits

connected directly to utilization points (socket outlets & similar points)
of the low-voltage MAINS installation.  Examples are measurements
on  MAINS  CIRCUITS  of  household  appliances,  portable  tools  & 
similar equipment.
