General Description - Velleman DVM835 Mode D'emploi

 When carrying out measurements on a TV set or switching power
circuits, always remember that the meter may be damaged by any high
amplitude voltage pulses at test points.
 Always be careful when working with voltages above 60 VDC or 30 VAC
rms. Keep your fingers behind the probe barriers at all times during
measurement.
 Never perform resistance, diode or continuity measurements on live
circuits. Make sure all capacitors in the circuit are depleted.

7. Overvoltage/Installation Category
DMMs are categorized depending on the risk and severity of transient
overvoltage that might occur at the point of test. Transients are short-lived
bursts of energy induced in a system, e.g. caused by lightning strike on a
power line.
The existing categories according EN 61010-1 are:
A CAT I-rated meter is suitable for measurements on protected
CAT I electronic circuits that are not directly connected to mains power, e.g.
electronics circuits, control signals...
A CAT II-rated meter is suitable for measurements in CAT I-
environments and mono-phase appliances that are connected to the
CAT mains by means of a plug and circuits in a normal domestic
II environment, provided that the circuit is at least 10 m apart from a
CAT III- or 20 m apart from a CAT IV-environment. E.g. household
appliances, portable tools...
