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!)
Indicates European 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 7).
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 8.
• 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.
• During measurement, the Testing without tripping of RCCB:
RCCB may be tripped unintentionally. This may be attributable
to a high degree of sensitivity towards short current peaks,
especially with those variants with IΔN = 10 mA and 30 mA,
or the RCCB may be defective or a certain leakage current
may flow through the measured electrical circuit which, in
addition to the current that is produced by the test instrument,
trips the RCCB.
• 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 , the latter may switch off. This testing systems with RCCBs
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.
• Use original accessories only.
• Max. permissible voltage between test probe and ground is
300 V!
• Maximum permissible voltage between the test probes is
300 V!
Opening of Equipment / Repair
The equipment may be opened only by authorized service per-
sonnel 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 ser-
vice 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.
1.4 General Device Description
The test instrument is enclosed in a compact with a pathousing -
ented means of retaining the test probes.
The high-contrast, four-color OLED display assures legiexcellent -
bility. When performing measurements under unfavorable light
conditions, measuring point illumination can be switched on –
white LED at the front.
The following measurements can be performed with the Metraline
Z
check
:
• Fault loop impedance with short-circuit current
• Fault loop impedance with short-circuit current without trip-
ping the RCCB for measurements of RCCBs with a nominal
current of 100 mA or 300 mA
• Line impedance with short-circuit current
• Line voltage
• Phase detection
The Metraline Z
check
allows for the evaluation of measured imped-
ance in consideration of type, nominal current and disconnection
time. A table with the parameters of various protective devices is
included in device memory (see section 5 on page 9 in these
operating instructions.

1.6 Environment
The shipping package is made of recyclable cardboard. Batteries
must be disposed of in accordance with applicable regulations.
This device may not be disposed of with the trash. Further infor-
mation regarding the WEEE mark can be accessed on the Inter-

2 Device Description
2.1 Housing
Figure 2.1: Top View
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.
