Please observe the following safety precautions:
The voltages indicated on the METRAVOLT VT
1500 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 ... +55°C.
Hold the instrument by its handles only, to avoid
covering the display or touching the test
elecrodes.
The maximum on-period is 2 minutes.
Only qualified persons may carry out work with
this device. The user needs to be familiar with
the risks involved in measuring voltage as well as
with the observance of safety regulations and the
proper use of the voltage detector.
Work may only be performed with the 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: DGUV V3 or EN 50110-1).
The function of the voltage tester must be
checked briefly before and whenever possible
after use.
Carry out the function test.
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 an indication for hazardous voltage and not as
measurement value.
Due to its relatively high internal impedance in
the case of existing interference voltages, this
voltage detector cannot reliably indicate the
absence of operating voltage when the load
buttons are not pressed.
If the display shows "voltage present" on a
part that is considered to be separated from the
installation, it is recommended to repeat the test
while pressing the push buttons (connected load)
in order to verify and establish the condition
"operating voltage not present".
In the case of determination of phase conductors
and phase sequence the perceptibility of the display
may be impaired, e.g. when using insulating
protective gear, in unfavourable locations, for
example on wooden ladders or insulating floor
coverings, as well as under 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 personnel.
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.
