Gossen MetraWatt METRAVOLT 12D+L Mode D'emploi page 16

Please observe the following safety precautions:
 The voltages indicated on the METRAVOLT 12D+L
are rated voltages. The voltage tester may only be
used in systems working within this rated voltage
range.
 Faultless indication of display values is only
guaranteed between -15°C ... +45°C.
 Hold the instrument by its handgears only, to
avoid covering the display or touching the test
elecrodes.
 The maximum on-period of the METRAVOLT
12D+L is 2 minutes.
 Only qualified persons may carry out work with
these device. The user needs to be farmiliar with
the risks for measuring voltage and compliance
with safety regulations and the proper use of the
voltage detector.
 Workings may only be performed with appropri-
ate personal protective equipment.
Observe the minimum object distance to other
plant components that are energized or earthed
and use personal protective equipment as speci-
fied by national accident prevention regulations
(in Germany: BGV A3 or VDE 0105-100).
 The function of the voltage tester must be
checked briefly before and whenever possible
after the use. Carry out the function test and
check the instrument at a known voltage source
(AC and DC). If the indication of one or several
systems fails in the course of checking, the
instrument must not be used again.
 The red LED (LV-indication) only serves
as a indication for hazardous voltage and not as
measurement value.
 This voltage detector may not permit to clearly
indicate the absence of operating voltage in case
of interference voltage because of its relatively
high internal impedance.
When the indication "voltage present" appears
on a part that is expected to be disconnected of
the installation, it is recommended confirming by
an other means that there is no operating voltage
on the part to be tested.
 With determination of phase conductors and
phase sequence the perceptibility of the display
may be impaired, e.g. when using insulating
protective gears, in unfavourable locations, for
example on wooden ladders or insulating floor
coverings, as well as with unfavourable lighting
conditions and in an improperly earthed AC
voltage system.
 Before use, the battery compartment must be
closed.
 The voltage tester may only be dismantled by
authorised personnal.
 Before using the device check the housing and
connecting line for visible damage. If damages
are visible the voltage tester may not be placed into
operation. In case of strong dirt contamination, the
tester must be cleaned before use.
 The tester has to be stored in a clean and dry
environment.
