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 3.5 on page 7)

CAUTION

• Do not touch electrically conductive parts, test probes etc.
when the device is switched on and voltage might still be con­ducted 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 5 on page 7.

• If the device is moved from a colder to a warmer room, con­densation may occur, in which case a brief period of acclima­tization is advisable.

• We recommend removing the batteries during lengths 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.

• Use original accessories only.

• Maximum permissible voltage between test probe and ground
is 300 V!

• Maximum permissible (externally applied) voltage between the
test probes is 600 V!

Opening of Equipment / Repair

The equipment may be opened only by authorized service per­sonnel to ensure the safe and correct operation of the equipment
and to keep the warranty valid.

Even original spare parts may be installed only by authorized ser­vice personnel.

In case the equipment was opened by unauthorized personnel,
no warranty regarding personal safety, measurement accuracy,
conformity with applicable safety measures or any consequential
damage is granted by the manufacturer.

The test instrument consists of a compact housing with a pat­ented means of retaining the second test probe.

The high-contrast, four-color OLED display assures excellent legi­bility. When performing measurements under unfavorable light
conditions, measuring point illumination can be switched on –
white LED at the front.

The test instrument is capable of the following measurements:
– Insulation resistance with test voltages of 50 to 1000 V
– Surge protection devices with test voltages of 50 to 1000 V
– Direct and alternating voltages

For transport purposes, the movable test probe can be attached
to the housing and retained by a magnet such that both metal tips
are simultaneously recessed and protected.

In order to charge batteries which have been inserted into the
instrument, the flexible test probe’s connector plug must be
removed and the slide must be pushed to the left, so that the
socket at the right is made accessible and the charger can be
plugged into it.
