1.3 Safety Precautions
Read the operating instructions thoroughly and carefully before
using your instrument. Follow all instructions contained therein.
Make sure that the operating instructions are available to all users
of the instrument.
Meanings of Symbols on the Instrument
This device is equipped with double
or reinforced insulation.
Danger of injury due to electrical current,
warning regarding dangerous electrical voltage
Warning concerning a source of danger
(attention, observe documentation!)
EC mark of conformity:
This instrument fulfills all requirements of applicable
European directives.
Before using the instrument, it must be assured that it is safe.
Do not use if:
• Visible damage is apparent
• The battery compartment lid is missing
• The device has been stored under unfavorable conditions for
a lengthy period of time
• The device has been handled impermissibly, e.g. has been
dropped from a height of 1 meter or more
• The test instrument does not function as described in these
operating instructions (if this is the case, we recommend
resetting the device as described in section 3.6 on page 6).
CAUTION
• Do not touch electrically conductive parts, test probes etc.
when the device is switched on and voltage might still be con-
ducted by a test probe – DANGER OF INJURY!
• Only use test probes which are included with the instrument
or are available as accessories.
• The device must be switched off and no voltage may be
applied when exchanging accessories.
• It is absolutely essential to adhere to all safety precautions,
regulations and standards when performing measurements.
• No keys may be pressed when connecting the instrument to a
device under test.
• The test instrument may not be subjected to the influence of
aggressive substances, gases, vapors, liquids or dust.
• The test instrument may only be used under the conditions
listed in the technical data in section 4 on page 7.
• If the device is moved from a colder to a warmer room, con-
densation may occur, in which case a brief period of acclima-
tization is advisable.
• We recommend removing the batteries during lengthy periods
of storage.
• Two relatively strong magnets are integrated into the test
instrument. Avoid close proximity to magnetically sensitive
objects such as watches, credit cards and the like.
• The illustrations in these operating instructions are drawings
and may therefore deviate from reality.
Exclusion of Liability
When testing systems with RCCBs, the latter may switch off. This
may occur even though the test does not normally provide for it.
Leakage currents may be present which, in combination with the
test current of the test instrument, exceed the shutdown thresh-
old value of the RCCB. PCs which are operated in proximity to
such RCCB systems may switch off as a consequence. This may
result in inadvertent loss of data. Before conducting the test, pre-
cautions should therefore be taken to ensure that all data and
programs are adequately saved and the computer should be
switched off if necessary. The manufacturer of the test instrument
assumes no liability for any direct or indirect damage to equip-
ment, computers, peripheral equipment or data bases when per-
forming the tests.
