Important Notes
1.10 Measurement Categories
This instrument is designed for measurements on circuits
that are only indirectly connected to the low voltage mains
or not connected at all. The instrument is not intended for
measurements within the measurement categories II, III or
IV.
The measurement categories refer to transients that are
superimposed on the mains voltage. Transients are short,
very fast (steep) current and voltage variations which may
occur periodically and non-periodically. The level of poten-
tial transients increases as the distance to the source of
the low voltage installation decreases.
❙ Measurement CAT IV : Measurements at the source of
the low voltage installations (e.g. meters)
❙ Measurement CAT III : Measurements in building
installations (e.g. power distribution installations, power
switches, firmly installed sockets, firmly installed engines
etc.).
❙ Measurement CAT II : Measurements on circuits
electronically directly connected to the mains (e.g.
household appliances, power tools, etc.)
❙ 0 (instruments without measured measurement
category): Other circuits that are not connected directly to
the mains.
1.11 Mains voltage
The instrument has a wide range power supply from 105
to 253 V, 50 or 60 Hz ±10%. There is hence no line voltage
selector. The line fuse is accessible on the rear panel and
part of the line input connector. Prior to exchanging a fuse,
the line cord must be pulled out. Exchange is only allowed
if the fuse holder is undamaged. It can be taken out using
a screwdriver put into the slot. The fuse can be pushed out
of its holder and exchanged. The holder with the new fuse
can then be pushed back in place against the spring. It is
prohibited to ”repair“ blown fuses or to bridge the fuse.
Any damages incurred by such measures will void the
warranty.
Type of fuse:
Size 5 x 20 mm; 250V~, C; IEC 127, Bl. III;
DIN 41 662 (or DIN 41 571, Bl. 3).
Cut off: slow blow (T) 2A.
1.12 Batteries and Rechargeable Batteries/Cells
1. Cells must not be disassembled, opened or crushed.
2. Cells and batteries may not be exposed to heat or fire.
Storage in direct sunlight must be avoided. Keep cells
and batteries clean and dry. Clean soiled connectors
using a dry, clean cloth.
3. Cells or batteries must not be short-circuited. Cells or
batteries must not be stored in a box or in a drawer
where they can short-circuit each other, or where they
can be short-circuited by other conductive materials.
Cells and batteries must not be removed from their
original packaging until they are ready to be used.
4. Keep cells and batteries out of reach of children. Seek
medical assistance immediately if a cell or battery was
swallowed.
5. Cells and batteries must not be exposed to any me-
chanical shocks that are stronger than permitted.
6. If a cell develops a leak, the fluid must not be allowed
to come into contact with the skin or eyes. If contact
occurs, wash the affected area with plenty of water
and seek medical assistance.
7. Improperly replacing or charging cells or batteries can
cause explosions. Replace cells or batteries only with
the matching type in order to ensure the safety of the
product.
8. Cells and batteries must be recycled and kept separate
from residual waste. Cells and batteries must be recycled
and kept separate from residual waste. Rechargeable bat-
teries and normal batteries that contain lead, mercury or
cadmium are hazardous waste. Observe the national reg-
ulations regarding waste disposal and recycling.
If the information regarding batteries and rechargeable batteries/
cells is not observed either at all or to the extent necessary, prod-
uct users may be exposed to the risk of explosions, fire and/or se-
rious personal injury, and, in some cases, death. Batteries and re-
chargeable batteries with alkaline electrolytes (e.g. lithium cells)
must be handled in accordance with the EN 62133 standard.
