measurement input. The auxilary output (AUX OUT) is a 
multi-purpose output with the function as component tes-
ter, trigger output, pass/fail and function generator.

When performing measurements in category II, III or IV 
circuits, it is mandatory to insert a probe that reduces the 
voltage so that no transient overvoltages will be applied 
to the instrument. Direct measurements (without galvanic 
isolation) to category II, III or IV circuits are prohibited. The 
measuring circuits are considered not connected to the 
mains if an isolation transformer in compliance with class 
II is used. It is also possible to perform measurements on 
the mains if appropriate transformers (e.g. current connec-
tors) are used that are in compliance with safety class II. 
The measurement category (for which the manufacturer 
specified the required transformer) must be observed.

Measurement categories
The measurement categories refer to transients from 
the power system. Transients are short, very fast (steep) 
current and voltage variations which may occur periodi-
cally and nonperiodically. The level of potential 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 installa-
tions (e.g. power distribution installations, power switches, 
firmly installed sockets, firmly installed engines etc.).
Measurement CAT II: Measurements on circuits elect-
ronically directly connected to the mains (e.g. household 
appliances, power tools, etc.)
Without category (previously Measurement CAT I): Elect-
ronic devices and fused circuits in devices.

The instrument has a wide range power supply from 100 
to 240 V (±10%), 50 or 60 Hz. There is hence no line vol-
tage 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 must be exchanged with the 
identical type (type informations below). 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: IEC 60127 - T2H 250V, Size 5 x 20 mm.

1.  Cells must not be taken apart or crushed.
2.  Cells or batteries must 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 ori-
ginal packaging until they are ready to be used.

4.  Keep cells and batteries out of the hands of children. If 

a cell or a battery has been swallowed, seek medical 
aid immediately.

5.  Cells and batteries must not be exposed to any mecha-

nical 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 aid. 

7.  Improperly replacing or charging cells or batteries that 

contain alkaline electrolytes (e.g. lithium cells) can 
cause explosions. Replace cells or batteries only with 
the identical type in order to ensure the safety of the 
product.

8.  Cells and batteries must be recycled and kept separate 

from residual waste. Rechargeable batteries and nor-
mal batteries that contain lead, mercury or cadmium 
are hazardous waste. Observe the national regulations 
regarding waste disposal and recycling.
