Safety Instructions; Intended Use - Würth DUO Traducción Del Manual De Instrucciones De Servicio Original

The voltage tester must be
checked just prior to use.
Ensure that measuring lines
and device are in proper
working order.
Check the device by connecting it to a known
■
power source, e.g. a 230 V socket.
If the display for one or more functions fails
■
in the process, the device must no longer
be used and must be checked by qualified
specialist technicians.
Electric shock may result in major injuries or
■
death and may endanger the functionality of
objects (e.g. damage to the device).
Read and comply with the five safety rules:
■
1. Disconnect mains
2. Prevent reconnection
3. Test absence of voltage by approved
means (establish absence of voltage using
2-pole voltage indicators)
4. Earthing and short-circuiting
5. Protect adjacent live parts using covers
Avoid operating the device in the vicinity of
■
electric welding machines, induction heaters
and other electromagnetic fields.
After abrupt changes in temperature, the
■
device must be allowed to adapt to the new
ambient temperature and stabilise for approx.
30 minutes.
Do not expose the device to high temperatures
■
for any length of time.
Avoid dusty and humid ambient conditions.

Intended use

IMPORTANT:
The functions below marked ** refer
solely to the Elmo® DUO PLUS Voltage
Tester!
DC voltages from 6 V to 1000 V and AC voltages
from 6 V to 1000 V can be measured relative to
earth.
Furthermore, polarity, phase sequence and continu-
ity checks up to 200 kΩ as well as RCD tests can be
performed.

Safety instructions

Measurement devices and accessories are not
■
toys and should always be kept away from
children!
In commercial facilities the accident preven-
■
tion regulations (in Germany issued by the
commercial trade association for the safety
of electrical systems and equipment) must be
observed.
Hold the device only at the handles, avoid
■
touching the test probes!
Always check for absence of voltage at both
■
terminals!
Do not use with the battery compartment open!
■
The measuring leads must be disconnected
from the measuring circuit during battery
replacement.
A correct display is ensured within the tem-
■
perature range of -10°C to +55°C.
The additionally displayed warning symbol
■
and acoustic signal at voltages > 35 V are
intended only as a warning of potentially fatal
voltages, not for measurement.
Check the warning signal for audibility in loud
■
working environments before starting tests.
Replace the batteries immediately if a contin-
■
uous warning signal sounds when switching on.
In order to protect the device from damage,
■
remove the batteries if the device is not in use
for a prolonged period of time.
Do not use the various displayed signals of
■
the device including the ELV limit value for
measurement purposes.
Use only genuine Würth accessories
■
and spare parts.
Thanks to the rotating spacer, single-handed opera-
tion is possible during voltage measurement.
Thanks to its high degree of protection (IP65), the
Elmo® voltage tester is also suitable for use in
hostile operating conditions.
Any other use is considered improper.
The user is liable for any damage in the
event of improper use.
