Caution, risk of electric shock.
The marking “   ” on the multimeter represents Caution,
risk of danger, important information, refer to the manual.
In order to find out the nature of the potential HAZARD
and any actions which have to be taken consult the 
manual in all cases where “   ” is marked.
The marking “    ” on the multimeter represents
Functional earth terminal.
The marking “     ” on the multimeter represents
Equipment protected throughout by DOUBLE
INSULATION or REINFORCED INSULATION.
