For your safety

Proper use

The device is used to test alternating electric fields. The device is solely intended for
the applications described in these instructions, such as tests of voltage, single-pole
phases, rotational field, flow and diodes. The device may only be used in the indicated
nominal voltage range and in electric systems up to 1,000 V AC / 1,500 V DC.
Proper use also includes compliance with all information provided in these instructions.
Any use beyond and differing from the proper use is considered improper use.
Improper use
If the test tips L1- 14 or L2+ 2 are bent do not continue to use the device.
Use the test tips L1- or L2+ exclusively for testing voltage.
Do not use the device's indication signals for measurement purposes.

User requirements

Permissible users are electrical specialists or expert persons who are accordingly
trained and who are aware of the risks associated with operating the device and how
to avoid them.
Only persons who can be expected to implement their work reliably are permissible
as users. Any persons, whose reactions are influenced by substances such as drugs,
alcohol or medications, are not permissible.
Based on their training, knowledge and experience as well as knowledge of the
applicable standards and regulations, users are capable of carrying out work involving
the device professionally and safely. In addition, users are capable of independently
recognising and avoiding the risks involved with this work.

Residual risks

The device is up-to-date technology and meets current safety requirements.
Nevertheless, there are residual risks that require careful action.
Danger of injury from improper handling of batteries!
With improper use, batteries may explode or liquids that are harmful to health
may seep out. Coming into contact with battery liquid may lead to injury and
death.
Never try to charge the batteries.
Do not short circuit the contacts "+" and "-" of the battery.
Do not expose batteries to moisture or humidity.
Do not change the shape of the batteries, do not open or disassemble
batteries.
Keep batteries away from hot environments.
If skin comes in contact with seeping liquid, thoroughly rinse the affected
area with water.
If seeping liquid comes into contact with eyes, rinse eyes with clean water
and contact a physician.
If you swallow seeping liquid, rinse your mouth, drink plenty of water and
contact a physician. Do not induce vomiting.
Mortal danger from electric voltage!
Coming in contact with live parts constitutes immediate mortal danger from
electric shock.
If the insulation is damaged, immediately disconnect the device and do not
continue to use the damaged device.
Do not carry out repairs independently on the device. Instead, contact
customer service.
Keep the device away from moisture and humidity to prevent a short circuit.

Before use

Safety before use

Before each use test that the device is working with no problems by checking
a known voltage source, e.g. a 230 V socket. Check for cable breaks and
seeping batteries.
During use, hold the device using the grips provided for this purpose. Never
touch the test tips L1- 14 and L2+ 2 and do not cover the LED display 13 or
LC display 7 .
Keep the device away from moisture, humidity and explosive environments.
Ensure the batteries are working before to each use 10 and replace them if
needed.
Do not use the device if the battery compartment is open 9 !
If your safety is no longer assured, switch off the device and secure against use.
Safety is no longer assured in the following cases, for example:
The housing 12 is broken or there are cracks in the housing.
The device no longer carries out the required tests without error.
The device was stored for too long in poor conditions (see section on
„Transport and storage" on page 13).
The device was damaged during transport.
