Carefully read the instruction manual before 
using  the  multimeter  and  obey  the  instruc-
tions therein. 

 

The  multimeter  may  only  be  used  by  per-
sons  who  are  able  to  recognise  the  risks  of 
contact  and  take  due  precautions  to  avoid 
them. 

This multimeter is not a toy and must not fall into 
the hands of children. 

 

Do  not  place  it,  keep  it  or  use  it  anywhere 
within reach of children. 

 

When  the  multimeter  is  used  by  teenagers, 
trainees  etc.,  a  suitable  person  should  su-
pervise  to  ensure  the  equipment  is  used 
safely. 

 

If measurements  are made  where  there  are 
any risks of coming into contact with electric-
ity, a second person is to be informed. 

The  assumption  needs  to  be  made  that  unfore-
seen  voltages  may  be  present  in  the  vicinity  of 
objects  being  measured  (e.g.  faulty  equipment 
or capacitors). 

 

Before  using  the  multimeter,  check  the 
housing  and  measuring  leads  for  damage 
and  if  there  should  be  any  malfunctions  or 
visible  damage,  the  multimeter  is  not  to  be 
used. Pay specific attention to the insulation 
for the measuring sockets. 

 

Be particularly careful  when measuring volt-
ages  in  excess  of  33 V  AC  (RMS)  or  70 V 
DC. 

 

For voltages which are in excess of 33 V AC 
or  70  V  DC,  only  use  safety  measurement 
leads conforming at least to CAT II. 

 

The authorised measuring range is not to be 
exceeded. If measurements are made when 
the  magnitude  of  the  variable  is  unknown, 
always  select  a  large  measuring  range  be-
fore shifting down to lower ones. 

 

The  multimeter  may  not  be  used  to  make 
measurement  on  circuits  which  exhibit  co-
rona discharge (high voltage). 

 

Particular  care  is  to  be  taken  when  making 
measurements  on  high-frequency  circuits 
where dangerous voltages may arise due to 
superimposition of components. 

 

Make  very  sure  that  the  voltage  value  be-
tween  the  measured  contact  and  earth  or 
between  the  ground  socket  and  the  meas-
urement socket does not exceed 1000 V. 

 

In order to check that the multimeter is ready 
to  use,  select  the  battery  test  function.  Af-
terwards, it is then possible to check that the 
voltage  source  is  disconnected  and  no  volt-
age is present. 

 

 

The  multimeter  may  only  be  used  in  a  dry, 
dust-free  environment  with  no  risk  of  explo-
sions occurring. 

 

When  measuring  current  in  a  circuit,  make 
sure to switch off the power before connect-
ing the multimeter into the circuit. 

 

When  making  measurements,  always  con-
nect the ground lead first. Disconnect the sig-
nal measurement lead before unplugging the 
ground. 

 

Turn  off  the  multimeter  before  opening  the 
casing,  disconnect  the  power  to  the  circuit 
and  the  measuring  leads  from  the  multime-
ter.
