Self and personnel protection
■
Electric shock may result in major injuries or
death and may endanger the functionality of
objects (e.g. damage to the device).
■
The proper function of the voltage tester must
be checked shortly before use.
■
Ensure that measuring leads and the 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 personnel.
■
Hold the device only at the handles, avoid
touching the test probes!
■
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 two-pole
voltage indicators)
4.
Ground and short-circuit
5.
Protect adjacent live parts using covers or screw
off
Safety in the workplace
■
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 for approx. 30 minutes to
stabilise the IR sensor.
■
Do not expose the device to high temperatures
for any length of time.
■
Avoid dusty and humid ambient conditions.
■
In commercial facilities the accident prevention
regulations (in Germany issued by the commer
-
cial trade association for the safety of electrical
systems and equipment) must be observed.
General safety instructions
■
Always visually check the device for damage
before initial use and after transport. Ensure
any damage is repaired by trained service
personnel prior to initial use.
■
The device must not be operated in damp
conditions.
■
Do not use with the battery compartment open!
■
The measuring leads must be disconnected
from the measuring circuit during battery
replacement.
■
In order to protect the device from damage,
remove the batteries if the device is not in use
for a prolonged period of time.
■
Measurement devices and accessories are not
toys and should always be kept away from
children!
■
Only use the enclosed safety measuring leads
or equivalent measuring leads that comply with
the correct measuring category CAT IV 600 V.
■
To avoid electric shocks, precautionary
measures must be observed when working
with voltages greater than 120 V (60 V) DC
or 50 V (25 V) eff. AC. According to DIN
VDE standards, these values represent the
limit at which exposed touchable surfaces
are still safe. (Values in brackets apply for, for
example, medical or agricultural applications)
■
The testing device must only be used in the
specified measuring ranges.
■
Use only genuine Würth accessories
and spare parts.
