1. Safety Precautions 
This  product  complies  with  the  requirements  of  the  following 
European  Community  Directives:  2004/108/EC  (Electromagnetic 
Compatibility)  and  2006/95/EC  (Low  Voltage)  as  amended  by 
2004/22/EC  (CE-Marking).  Overvoltage  category  III  1000V;  over-
voltage category IV 600V; pollution degree 2. 
CAT I:  For signal level, telecommunication, electronic with small 
transient over voltage 
CAT II:  For  local  level,  appliances,  main  wall  outlets,  portable 
equipment 
CAT III:  Distribution level, fixed installation, with smaller transient 
over-voltages than CAT IV. 
CAT IV:  Units and installations, which are supplied overhead lines, 
which are  stand  in a  risk of persuade of a  lightning,  i.e. 
main-switches  on  current  input,  over-voltage-diverter, 
current use counter. 
To  ensure  safe  operation  of  the  equipment  and  eliminate  the 
danger of serious injury due to short-circuits (arcing), the following 
safety precautions must be observed. 
Damages resulting from failure to observe these safety precautions 
are exempt from any legal claims whatever. 
*  Do not use this instrument for high-energy industrial installation 
measurement. This instrument is intended for use in installation 
over-voltage category III. 
*  Do not exceed the maximum permissible input ratings (danger 
of serious injury and/or destruction of the equipment).
