Safety Information
Read and understand this Instruction
Manual completely before using this
instrument. Failure to observe the warnings
and cautions in this Instruction Manual may
result in injury or death, or damage to the
instrument and other equipment or
property.
If this instrument is used in a manner not
specified in these instructions, the protec-
tion provided by the instrument may be
impaired. WARNING
-Examine the instrument and probes and
leads before use. Do not use the instru-
ment if it is wet or damaged, or if you
suspect it is not operating correctly.
-When using the instrument, test leads or
probes, keep your fingers behind the
finger guards.
-Remove the test lead from the instrument
before opening the battery cover or instru-
ment case.
-Always use the correct terminals, switch
position and range for measurements.
-Verify the instrument is operating correctly
by measuring a known voltage before
use. If in doubt, have the instrument
serviced.
-Do not apply more than the rated voltage
as marked on the instrument between
terminals, or between any terminal and
earth ground.
-Use caution when measuring voltages
above 30 Vac rms or 60 Vdc. These
voltages pose a shock hazard.
-To avoid incorrect readings that can lead
to electric shock, replace the battery as
soon as low battery indicator appears
in the display.
-Disconnect the circuit power and
discharge all high-voltage capacitors
before making resistance, continuity, or
diode measurements.
-Do not use the instrument in a Hazardous
Area or around explosive gasses or
vapours.

EN - 3
-Wear suitable Personal Protective
Equipment when working around or near
hazardous Live conductors which could
be accessible.
-Do not use the thermocouple to measure
the temperature of Hazardous Live
conductors or equipment.
Caution
-Disconnect the test leads from the test
points before changing the position of the
function rotary switch.
-Never connect the instrument to a source
of voltage with the function rotary switch in
Ω/ </Aposition.
- If possible, do not work alone, so
assistance can be given if required.
-Do not expose the instrument to extremes
of temperature or high humidity.
-If this instrument is used in the vicinity of
equipment which generates electro
magnetic interference, the display may
become unstable or the measurements
may be subject to large errors.

Maintenance
Do not attempt to repair this Instrument. It
contains no user-serviceable parts. Repair
or servicing should only be performed by
qualified personnel. This instrument
should be calibrated yearly, or more
frequently if used in harsh conditions or if
it is suspected of being inaccurate.
For calibration and repair contact RS
Components - the address is given at the
end of these instructions.
Cleaning
Periodically wipe the case with a damp
cloth and detergent. Do not use abrasives
or solvents.

EN - 5
To conserve battery power, the Auto
Power-off function will turn the instrument
off approximately 10 minutes after the last
operation.
10min
To disable the Auto Power-off function:
Turn the instrument off, press and hold the
“Backlight” button and turn the rotary switch
to the required function. The auto Power-off
is disabled until the next time the instru-
ment is turned off and on again.

Sicherheitshinweise
Vor der Verwendung dieses Messgeräts
muss diese Bedienungsanleitung voll-
ständig gelesen und verstanden werden.
Nichtbeachtung der Warnhinweise und
Vorsichtsmaßnahmen in dieser Bedienung-
sanleitung kann zu Verletzungen oder Tod
und zu Beschädigung am Messgerät und
anderen Geräten oderSachgegenständen
führen.
Bei nicht bestimmungsgemäßem Gebrauch
und bei Nichtbeachtung der Sicherheitshin-
weise können die integrierten Schutzfunk-
tionen des Geräts unwirksam werden.
VORSICHT!
- Vor der Verwendung das Gerät,
Prüfspitzen und Prüfkabel untersuchen.
Das Gerät nicht verwenden, wenn es
beschädigt oder nass ist, oder falls es
anscheinend nicht ordnungsgemäß
funktioniert.
- Beim Einsatz des Geräts, von Prüfkabeln
oder Prüfspitzen die Finger hinter dem
Fingerschutz halten.
- Vor dem Öffnen der Batterieabdeckung
oder des Gerätegehäuses die Messlei-
tung vom Gerät entfernen.
- Stets auf Verwendung der richtigen
Anschlüsse, Schalterpositionen und
Messbereiche achten.
- Überzeugen Sie sich vor der
Verwendung, dass das Gerät einwandfrei
funktioniert, indem Sie eine bekannte
Spannung messen. In Zweifelsfällen
muss das Messgerät gewartet werden.
- Die angelegte Spannung zwischen den
Klemmen sowie zwischen den Klemmen
und der Masse darf die auf dem
Messgerät angegebene Nennspannung
nicht überschreiten.
- Vorsicht bei Messungen in der Nähe von
Wechselspannungen über 30 Veff. AC.
oder Gleichspannung über 60 VDC. Bei
diesen Spannungen besteht die Gefahr
eines Stromschlags.
