Safety
2.1
Basic information about safety
The product is built according to the state of the art and the
recognized safety regulations. Despite this, there might be danger
to life and limb of the user or a third person in case of improper
use, and the product or other material assets might be affected.
• If the product is operated by persons who are untrained or have
not been instructed.
• If the product is not used for its intended purpose.
• If the product is maintained or repaired improperly.
• If the product is not operated in technically perfect condition.
The product operates in mains or battery operating mode. It
contains components at which high currents and voltages are
present. Provided that it has been correctly installed, the product is
earthed and corresponds to protection class: see type plate.
Maintenance work must only be carried out by
service technicians of the manufacturer or his
contractual partner.
This operating manual is an essential constituent of the product
and applies exclusively to this product from the manufacturer.
The information contained in this operating manual is binding. This
operating manual must be read in full and the information therein
must be followed at all times.
Non-observance, manipulation or misuse of the instructions and
safety instructions given in this manual can result in considerable
danger.
In the event of erroneous operation or misuse, the life and limb of
the operator or third parties may be put at risk, the product and
other assets belonging to the operator may be damaged, or
efficient work with the product may be restricted.
Besides the instructions and the binding regulations relating to the
prevention of accidents that are applicable in the country and
place of use, the recognized professional rules for safe and
professional work must also be observed.
Additional warnings are provided in order to guarantee adequate
safety for personnel. Adequate safety when handling the product
will only be guaranteed when this is observed.

Safety notes
This documentation contains notes that must be taken into
consideration for personal safety and avoiding personal injuries
and damage to property.
If you see one of the symbols shown in the documentation, highest
attention is required.
Please observe that working on live parts of all kinds is
dangerous!
Even low voltages from 25 V AC and 60 V DC on may
be dangerous to human life!
Dangerous voltages might occur on the test sample
during insulation testing (RInsu) or when using the
alternative leakage current measuring method.
Under no circumstances should persons be electrically
involved in test procedures. It is not permitted to
measure leakage currents via persons.
If it is assumed that safe operation is no longer possible,
the device must be switched off immediately and
secured against unintended operation. Safe operation
can be assumed to be no longer possible, if
• the device exhibits visible damage,
• the device no longer works,
• if the device has been stored under unfavorable
conditions for a longer period of time or has been
exposed to extraordinary stress during transport.
Please use only the original measuring lines provided or
corresponding safety measuring accessories!
For device protection and for functional testing, the
measuring voltages are monitored. In case of a fault, an
error will be indicated on the display. Measurement will
be interrupted. In case of a fault current of ≥ 25 mA, the
device will be switched off within 100 to 200 ms.
In order to detect short-circuits and body contacts
occurring behind the switch-on elements (switch,
thermostat, relay etc.) of the test sample, the test sample
must be switched on.
The test sample must be free of external voltage
(disconnected from the mains).
The device is not intended for measurements in
electrical installations!
Do not connect any external voltage to the "test socket"
and to the built-in jacks or the IEC connector. The device
might get damaged!
The appliance tester must be used only in the specified
operating and measuring ranges.
Pressing the "Pause" button will stop the measurement.
During the pause, the test socket remains live!
Clean the housing regularly with a damp cloth and then
wipe the wet surfaces dry.
Do not use any cleaning and polishing agents or
solvents.
For the testing of devices with the warning "High
leakage current!", the test must be carried out by
qualified electricians only!
The content of this documentation is intended to explain
the appliance tester and in no way replaces the currently
applicable test standards.
