resistance scale. If you cannot achieve
this, replace the battery with a new one
as follows:
1. Remove instrument from all circuits.
2. Remove the protective rubber holster
and open the battery case on the rear of
the instrument.
3. Loosen the 3 screws.
4. Replace the discharged battery with a
new battery (1.5V, AA, IEC LR6).
Respect correct polarity!
5. Close battery case and continue
measurements.
Fuse Replacement
If the fuse has blown due to current
range overload, please respect the
following references for fuse
replacement. Only use fuses with
specified current and voltage values,
switch-off characteristics and capacities.
1. Remove instrument from all circuits.
2. Remove the protective rubber holster
and open battery case on the rear of the
instrument.
3. Loosen the 3 screws.
4. Remove defective fuse.
5. Insert new fuse ensuring it is
positioned correctly (Fuse: 200mA /
250V, Fast Acting Martindale FUS-
F200). Using auxiliary fuses and short-
circuiting the fuse holders is prohibited
and can lead to instrument destruction
and serious personal injury.
Cleaning
If the instrument is dirty after usage, it is
advised to clean it by using a damp cloth
and mild household detergent. Never
use acid detergents or dissolvants. Do
not use until the unit has thoroughly
dried out.

instrument. The instrument has been
designed in accordance with the most
up-to-date safety regulations and
ensures safe, reliable measurement.
The compact AM5 multimeter is a useful
aid, for all standard measurements, to
the electrician on site, in industry or for
hobby electronics.
Analogue display.
DC & AC voltage measurement up to
500V.
DC current measurement up to 250mA.
Resistance measurement up to 2M
Ω
.
The AM5 is supplied with test leads.
When unpacking, check that the
instrument and the accessories are
complete and in good condition.
Symbols marked on the instrument:
Warns of potential danger,
observe the advice given in the
instruction manual.
Indicates a dangerously high
voltage.
Conformity symbol, the instrument
complies with the relevant
directives. It complies with the EMC
Directive (89/336/EEC) and the
standards EN 50081-1:1992 and EN
50082-1:1992. It also complies with the
Low Voltage Directive (73/23/EEC) and
EN 61010-1:1993.
Operator’s Safety
The instrument has left our factory in a
safe condition - to maintain this
condition, the user must pay attention to
the safety references contained in this
instruction manual.

thoroughly prior to using the instrument:
failure to understand these instructions
and to comply with the warnings and
instructions, can result in serious injury
or damage.
WARNING In order to avoid electrical
shock, proper safety measures have to
be taken when working with voltages
exceeding 30V AC rms, 42V peak or
60V DC.
WARNING
Prior to making any
measurement, ensure that test leads
and the test instrument are in perfect
condition. This measuring instrument
may only be used within the specified
ranges. The instrument may only be
opened for fuse or battery replacement
by competent persons.
Prior to opening the instrument, ensure
that it is switched off and disconnected
from any circuits.
