1 Safety Information
1.1 General Safety
−Carefully read this manual before using the instrument.
−Use the instrument according to these instructions only.
−Use the instruments only under environmental conditions described in the technical data.
−Personnel assigned to use the instrument must have read this reference manual and fully understood the
instructions herein.
−The instruments may only be operated by trained personnel. Any maloperation can result in damage to
property or persons.
−The input voltage shall not exceed the values rated in the technical data. With this product, only use
the power cable delivered or defined for the host country.
−There is no guarantee if you exceed the values for your safety.
−The power supply must be within the limits given in the technical data.
−Always make a visual inspection of used equipment such as leads and clamps before use.
−Use fuses (500mA) if you connect the instrument directly to voltage where no fuse is available or high
short circuit power is given.
−The product heats during operation. Make sure there is adequate ventilation. Ventilation slots must not
be covered!
−When connecting to the banana plug sockets, only use cables with 4mm/0.16” safety banana
connectors and plastic housing. Always insert plugs completely.
−DO NOT insert objects into sockets or ventilation slots.
−DO NOT open the instrument or remove any of its housing components. Don’t carry out any
modifications, extensions or adaptions at the instrument. If instrument is opened by the customer, all
guarantees are invalidated.
−DO NOT use the system if equipment covers or shields are removed.
−DO NOT use the system in rooms with flammable gases, fumes or dust or in adverse
environmental conditions.
−The use of the measuring system in schools and other training facilities must be observed by
skilled personnel.
−Please contact a professional if you have doubts about the method of operation, safety or the connection
of the system.
−Please be careful with the product. Shocks, hits and dropping it from already lower level may damage
your system.
−Do not switch on the system after transporting it from a cold into a warm room and vice versa. The
thereby created condensation may damage your system. Acclimatize the system unpowered to room
temperature.
−Maintenance must be executed by qualified staff only.
−DO NOT operate damaged equipment: Whenever it is possible that the safety protection features built
into this product have been impaired, either through physical damage, excessive moisture, or any other
reason, REMOVE POWER and do not use the product until safe operation can be verified by
service-trained personnel. If necessary, return the product to sales and service office for service and
repair to ensure that safety features are maintained.
−This manual is to be supplemented by existing national safety standards for accident prevention
and environmental protection.
−The instructions provided in this manual and the associated software and hardware manuals are
considered part of the rules governing proper usage.
−Observe local laws when using the instrument.
−The use of measuring devices under CAT II, III or IV conditions can be dangerous! Under these
conditions, only appropriately trained / tested / informed about safety precautions may take
measurements (for safety categories see also technical reference manual). If a measuring device, a
cable or an accessory of a lower category or voltage is used, this lower category / voltage applies to
the entire group (device + cable + accessories)

Page 6 of 78
For working on equipment under voltage use the guidelines given in EN50110.
Always follow the 5 golden safety rules:
1. Always switch off.
Meaning that the electrical installation must be disconnected from live parts on all poles. Block
all poles of the power source for every part of the operation. Switchgear of home or factory,
low voltage switch mode, the power of the machine control switch should be cut off. The power
supply circuit to be supplied to the electric appliance such as lamps and motors should be cut
off. If you remove the low-voltage rapid fuse, you should wear bracers, a helmet, and front
shields. If there is a capacitor, the residual charge must be discharged using appropriate tools.
2. Secure against reconnection.
Reliably prevent an accidental re-connection of an installation where work is in progress. This
is achieved for example by just replacing the unscrewed fuses in the low-voltage system by
lockable lock-out devices. Appropriate warning signs should be posted for viewing on the
operating device (switch handle, instrument actuator, control device, circuit breaker, etc.). It
should also be posted to closed electrical operating areas or locked switch cabinets. The
contents of the warning cover should warn you that you don’t manipulate the switch. In addition,
provide a name for the workplace location and supervisor. The power-off device should be
locked to a mechanical device. All keys must be kept in a safe place. If it is operated with the
control voltage of the energy or controller, such as springs, compressed air, it must take
measures to prevent the release or operation of energy.
3. Verify that the installation is dead
Use a suitable measuring / test equipment such as a voltage detector to verify on all poles that
the installation is dead. Check the correct function of the voltage detector prior to using it.
4. Carry out earthing and short-circuiting.
An important point of the five safety rules is earthing and short-circuiting at the workplace. This
measure ensures a voltage-free state for the duration of the work, also with regard to
influencing voltages, atmospheric overvoltage or accidental restarting. Earthing and short-
circuit areas should be visible at the workplace. Important: The relevant parts must be earthed
before they are short-circuited!
5. Provide protection against adjacent live parts
According to the five safety rules, adjacent parts are parts located in the vicinity zone. If parts
of an electrical installation in the vicinity zone of the work location cannot be disconnected,
additional precautions must be taken before work starts. In this case use insulating protective
shutters or covering material as protection against accidental contact. The hazard area should
be marked for clarity.

1.2 Battery Handling
Lithium-Ion rechargeable batteries require routine maintenance and care in their use and
handling. Do not leave batteries unused for extended periods of time, either in the product or
in storage. When a battery has been unused for 3 months, check the charge status and charge
or dispose of the battery as appropriate.
Please especially consider the following points for storing the device:
−Charge the battery more than 50% of capacity before storage.
−Charge the battery more than 50% of capacity at least once every three months.
−Store the battery at temperatures between 5 °C and 20 °C (41 °F and 68 °F).
−The battery self-discharges during storage. Higher temperatures (above 20 °C or
68 °F) reduce the battery storage life.
If you start instrument after over-discharge or you didn’t use it for a long time, the instrument
may take several minutes to start up (even if fans are active). The integrated PC will start
operation not before battery charge level will reach nominal operating conditions.
If you will not use the instrument for longer time, always switch the Power button
to OFF (bottom position). This enables the maximal power saving mode and will
protect your battery of being over-discharged. Over-discharge of Li-Ion batteries
has huge influence on their lifetime.

to the WEEE – directive. Do not throw away.
