Intended Use

Depending on the model the table multimeter allows measuring of different electric values like
e.g. AC and DC voltage, AC and DC current, resistance, frequency as well as capacity and
tem- perature. Furthermore diode and continuity tests can be conducted.
The table multimeter shows all measuring values in the double display. Measuring value and
device memory facilitate working with the table multimeter. The measuring connection is estab-
lished via BNC measuring sockets.
Measurements must only be made up to 1000 V maximum in the overvoltage range of CAT 0
and maximum 500 V in the range CAT II, respectively. The maximum voltage in the current
measur- ing range "Ampere" (A) must not exceed 500 V.
For automatic control and measuring value recording different interfaces are available depend-
ing on the model.
The maximum measuring voltages indicated on the device must never be exceeded. Use
divider probes if necessary.
The device should only be connected and operated by an earthed shockproof socket of the
pub- lic alternating currentgrid.
Any use, other than that described above, could lead to damage to this product and involves
the risk of short circuits, fire, electric shock, etc.
The product must not be changed or modified in any way. Do not open the housing!
Measurement in damp locations, outdoors or under adverse environmental conditions is not
permitted.
Unfavourable ambient conditions are:
- Wet conditions or high air humidity
- Dust and flammable gases, vapours or solvent,
- Thunderstorms or similar conditions such as strong electrostatic fields etc.
Always observe the safety notes included in these operating instructions.
This quick guide explains safety measures to make working with the device as safe as possible.
The individual functions of the device are described in more detail in the enclosed operating
manual.

Safety Instructions and Hazard Warnings

Please read all of the operating instructions before using the product for the
first time; they contain important information regarding the correct operation.
• The warranty will be void in the event of damage caused by failure to observe these safety
instructions! We do not assume any liability for any consequential damage!
• We shall not accept liability for damage to property or personal injury caused by incorrect
handling or non-compliance with the safety instructions! The warranty will be void in such
cases.
• The unauthorised conversion and/or modification of the product is inadmissible because of
safety and approval reasons (CE).
• The construction of the product corresponds to protection class 1. Only a correct earthed
mains socket (100 - 240 V~) of the public power supply should be used.
• The mains outlet must be located near to the device and be easily accessible.
• Measuring devices and devices connected to the power supply should be kept out of reach
of children. Therefore, be especially careful when children are around.
• Connect the measuring lines to the multimeter before connecting them to the measuring cir-
cuit to be tested. After finishing the measurements, first of all disconnect the measurement
contacts from the circuit before you disconnect the measuring lines from the multimeter.
• Take particular care when dealing with voltages exceeding 25V AC or 35V DC! Even at these
voltages it is possible to get a fatal electric shock if you touch electric conductors.
• Prior to each measurement, check your instrument and its measuring leads for damage.
Never carry out any measurements if the protecting insulation is defective (torn, ripped off,
etc.).
• To avoid electric shock, do not to touch the connections/measuring points directly or indirectly
during measurements.
• Never touch the probes outside of the marked handling area during a measurement. There is
danger of a life-threatening electric shock.
• Do not use the device shortly before or after a thunderstorm (lightning! // high-energy
overvoltages!). Make sure that your hands, shoes, clothing, the floor, the measuring device
and/or measuring lines, the circuits and also parts of it are always dry.
• Do not use the product within rooms or in bad ambient conditions where flammable gases,
vapours or explosive dust may be present or are present.
• Avoid operation near:
- strong magnetic or electromagnetic fields
- transmitter aerials or HF generators,
- These can affect the measurement
• For safety reasons, when measuring only use measuring cables or accessories which are
adjusted to the specifications of the multimeter. Only use double or additionally insulated
measuring accessories.
• If you have reason to assume that safe operation is no longer possible, disconnect the
device immediately and secure it against inadvertent operation. It can be assumed that safe
operation is no longer possible if:
- the device shows visible damage,
- the device no longer operates and
- after being stored under unfavourable conditions for a long period of time or
- it has been subjected to considerable stress in transit
• Never switch the device on immediately after having taken it from a cold in to a warm
environment. The condensation that forms might destroy your device. Allow the device to
reach room temperature before switching it on.
• Never disassemble the product! There is the danger of a lethal electric shock!
• Do not leave packing materials unattended. They may become dangerous playthings for
children.
• The product is only suited for dry indoor rooms (not bathrooms or similar damp interiors). The
device must not get wet or damp. There is the danger of a lethal electric shock!
• In commercial and industrial facilities the regulations for the prevention of accidents as laid
down by the professional trade association for electrical equipment and devices must be
observed.
• If you have doubts about how the equipment should be operated or how to safely connect it,
consult a trained technician.
• Handle the product with care. It can be damaged through impact, blows, or accidental drop,
even from a low height.
• Please also note the enclosed detailed operating instructions.
This device left the manufacture's factory in a safe and perfect condition.
We kindly request the user to observe the safety instructions and warnings contained in the
enclosed operating instructions so this condition is maintained and to ensure safe operation.
