8.3 Performing a test
Work on live installations may only be performed by trained electrical personnel with
relevant qualifications.
Turn the device on and set the parameters according to the residual current device under test.
Plug the device into a live socket outlet. The phase position (L) and the function of the protec-
tive conductor (earth symbol) are shown in the upper area of the display. The voltage indicator
is displayed on the right. The voltage should be 230 V.
If the display shows 400 V, a phase fault has occurred, and the tester must be disconnected
from the measuring circuit without delay. Make sure to check the installation for a possible fault.
If a fault voltage/contact voltage (50 V) is displayed, the installation has a faulty protective
conductor. Caution: high voltage. The installation must be immediately disconnected from the
power supply and checked.
You can perform the test when no error is displayed. Note that the electric circuit of the residual
current device under test is switched off during the test.
Press the "TEST" button to start the test. The display shows test parameters.
Unplug the tester from the socket outlet and briefly press the "OFF" button to turn it off.
You can re-enable the residual current device when all values are OK.
9 Troubleshooting
In purchasing this device, you have acquired a product which has been designed with state-
of-the-art technology and is operationally reliable. However, problems and malfunctions may
still occur.
This section tells you how to troubleshoot common issues:
Always observe the safety information in these instructions.
Problem
The device does not switch on.
The display lights up red and a
test cannot be started.
The display shows 400 V.
The display lights up red, and the
device emits a warning beep. The
display shows 50 V.
Any repair work other than that described above must be carried out by an au-
thorised technician. If you have any questions about handling the device, do not
hesitate to contact our technical support.
10 Cleaning and maintenance
10.1 General information
The device only needs occasional cleaning and battery change and otherwise requires no
special maintenance.
Regularly check the device for technical safety, for example, for signs of da-
mage to the housing or deformation, etc.
10.2 Cleaning the housing
Always observe the following safety information before cleaning the device:
Opening any covers on the product or removing parts – unless this is possib-
le by hand – may expose voltage-carrying components.
Ensure the device is disconnected from all measuring objects before cleaning
or servicing. Turn off the device.
Do not use abrasive detergents, petrol, alcohol or other similar chemicals to clean the device.
They may damage the surface of the device. In addition, the vapours emitted by these sub-
stances are explosive and harmful to your health. Do not use sharp-edged tools, screwdrivers
or metal brushes to clean the device.
To clean the device and the display, use a clean, lint-free, antistatic and slightly damp cleaning
cloth. Allow the device to dry completely before using it again.
Possible cause?
Are the batteries exhausted?
Change the batteries.
A fault has been detected in the installation (400 V).
A test cannot be started for safety reasons. Unplug
the device and switch the installation off. The instal-
lation must be checked.
A dangerous contact voltage has been detected for
the protective conductor. A test cannot be started for
safety reasons. Unplug the device and switch the
installation off. The installation must be checked.
11 Disposal
11.1 Product
All electrical and electronic equipment placed on the European market must be
labelled with this symbol. This symbol indicates that this device should be disposed
of separately from unsorted municipal waste at the end of its service life.
Owners of WEEE shall dispose of it separately from unsorted municipal waste.
Spent batteries and accumulators, which are not enclosed by the WEEE, as well
as lamps that can be removed from the WEEE in a non-destructive manner, must
be removed by end users from the WEEE in a non-destructive manner before it is
handed over to a collection point.
Distributors of electrical and electronic equipment are legally obliged to provide free take-back
of waste. Conrad provides the following return options free of charge (more details on our
website):
at our Conrad stores
at the collection points established by Conrad
at the collection points of public waste disposal agencies or at the collection systems set up
by manufacturers and distributors in accordance with the German Electrical and Electronic
Equipment Act.
The end user is responsible for deleting personal data from the WEEE to be disposed of.
It should be noted that different obligations about the return or recycling of WEEE may apply in
countries outside of Germany.
11.2 (Rechargeable) batteries
Remove the battery/rechargeable battery it and dispose of it separately from the product. You
as the end user are required by law (Battery Ordinance) to return all used batteries/rechargea-
ble batteries. Disposing of them in the household waste is prohibited.
Batteries/rechargeable batteries containing hazardous substances are labelled with
this symbol to indicate that disposal in household waste is forbidden. The abbrevi-
ations for heavy metals in batteries are: Cd = Cadmium, Hg = Mercury, Pb = Lead
(name on batteries/rechargeable batteries, e.g. below the trash icon on the left).
Used batteries/rechargeable batteries can be returned free of charge to local collection points,
our stores or battery retailers. You thus fulfil your statutory obligations and contribute to envi-
ronmental protection.
Batteries/rechargeable batteries that are disposed of should be protected against short circuit
and their exposed terminals should be covered completely with insulating tape before disposal.
Even empty batteries/rechargeable batteries can contain residual energy that may cause them
to swell, burst, catch fire or explode in the event of a short circuit.
