SAfETY INSTRUCTIONS
damages caused through not following these operating instructions will invalidate
the warranty/guarantee!
We assume no liability for consequential damage! Nor do we assume liability for
damage to property or personal injury caused by improper use or failure to observe
the safety instructions. Such cases will invalidate the warranty/guarantee.
An exclamation mark indicates important notes in these operating instructions
that should always be observed.
Personal safety
•
Measuring instruments and accessories are not toys and should never be in the hands of
children.
•
At commercial facilities, the accident prevention regulations of the association of the industrial
trade bodies for electrical systems and equipment must be observed.
•
In schools, training centres, computer and self-help workshops, handling of measuring instruments
must be supervised by trained personnel in a responsible manner.
•
Before measuring voltages, always make sure that the measuring instrument is not set to a
measuring range for currents.
•
The test prods have to be removed from the measured object every time the measuring range
is changed.
•
Be especially careful when dealing with voltages higher than 25 V AC or 35 V DC! Even at voltages
as low as these, there is a danger of fatal electric shock if you touch electric conductors.
•
Check the measuring device and its measuring lines for any damage before each measurement.
Never carry out any measurement if the protecting insulation is damaged (torn, ripped off, etc.)
•
To avoid possible electric shock, do not touch the connections/measuring points to be measured,
either directly or indirectly, during measurement.
•
Make sure that your hands, shoes, clothing, the floor, the measuring device and/or measuring
lines, the circuits and their parts are always dry.
•
If the hazard-free operation of the device cannot be guaranteed, the device must be taken out
of operation and secured against inadvertent operation. One may assume that hazard-free
operation is no longer possible if:
-
the device exhibits visible damage;
-
the device does not operate any longer ;
-
it has been stored under unfavourable conditions over a relatively long period of time; or
-
it has been subjected to transport-related stress.
