regard to safety. In order to maintain this condition, it is essen-
tial that the user observe the notes and warning comments
(Caution!) which are contained in this manual.
• Current measurements must only be performed with this mea-
suring unit in circuits which are themselves protected with a 2
A fuse or in which no voltages greater than 400 VACrms or 500
VDC can occur. The measuring unit must not be used in instal-
lation s in overvoltage category III in accordance with IEC 664
(industrial environment). The measuring device and instru-
ment leads are not protected against arc explosions (IEC 1010-
2-031, Section 13.101).
• Measuring devices and accessories do not belong in children's
hands!
• In industrial facilities the accident preventionregulations of
the Industrial Employers' Insurance Liability Association for
electrical systems and equipment must be observed.
• Current measuring devices must only be connected/operated
in series to the consuming device (test object).
• In schools, training facilities, hobby and self-helpworkshops
the handling of measuring units must be responsibly supervi-
sed by train ed personnel.
• When opening covers or removing components, except where
this can be performed manually, live parts may be exposed.
Connectionpoi nts may also be live. Before any adjustment,
maintenance, repair or replacement of components or assem-
blies, the device must be disconnected from all voltage sources
and circuits if it is necessary to open the device. If an adjust-
ment, a maintenance task or repair is subsequently required
on the opened device while it is live, these must only be per-
formed by a specialist who is familiar with the associated
4
hazards and relevant regulations (VDE-0100, VDE-0701, VDE-
0683).
• Capacitors in the device may still be charged, even when the
device has been isolated from all voltage sources and circuits.
• Take particular care when dealing with voltages greater than
25 V alternating (AC) or greater than 35 V direct voltage (DC).
Even at these voltages you can receive a lethal electric shock if
you touch an electrical conductor. Therefore, first of all switch
off the current source, connect the measuring device in series
with the circuit, set the required current measuring range on
the measuring device, and then switch the current source on.
After completion of the measurement, switch off the current
source.
• Before changing the measurement range or opening the hou-
sing to change the unit of measurement or the decimalpoint
the panelmeter must be switched free / isolated from the cir-
cuit.
• Before each measurement check the panelmeter and your
(connected) instrument leads for damage(s).
• Do not use the measuring device in unfavourable ambient
conditions, where combustible gases, vapours or dusts are or
may be present. For your own safety it is essential to prevent
the measuring device or instrument leads from becoming
damp or wet .
• In order to avoid electric shock, ensure that you do not touch
the measuring points, even indirectly, during measurement.
• If it is to be assumed that safe operation is no longer possible,
the device must be switched off and protected against unin-
