b) Symbols on the product
Symbol
Meaning
This symbol indicates that this product is built according to protection class
II. It is equipped with reinforced or dual insulation between the mains circuit
and the output voltage.
Earth potential
The symbol with the exclamation mark in the triangle is used if there is a risk
to your health, e.g. due to an electric shock.
AC voltage
DC voltage
Acoustic signals on/off
Diode
Capacitance measurement range
A lightning symbol in a square permits current measurements on uninsu-
lated, hazardous/active conductors and warns of the possible hazards.
Personal protective equipment must be used.
This product has been CE-tested and meets the relevant European guide-
lines.
CAT II
Measurement category II: for measuring electrical and electronic devices
that are directly supplied with a mains voltage via a mains plug. This cat-
egory also includes all lower categories (e.g. CAT I for measuring signal
and control voltages).
CAT III
Overvoltage category III for measuring in building installation (e.g. outlets or
sub-distribution). This category also includes all lower categories (e.g. CAT
II for measuring electrical devices). Measuring operation in CAT III is only
permitted with probe tips with a maximum free contact length of 4 mm or
with cover caps above the measuring probes.
Polarity marking (positive pole) for direct current measurement. The sym-
bols show the direction of the current flow to ensure the correct polarity
when measuring.
Position marker for the conductor to ensure the correct current measure-
ment.
