1 Safety Precautions

1.1 General

You have selected an instrument which
provides you with high levels of safety.

This instrument fulfills all requirements of
applicable European and national EC

guidelines. We confirm this with the CE
mark. The relevant declaration of conformity
can be obtained from GMC-I Messtechnik
GmbH.

The METRACLIP 63 / 64 current clamp is
manufactured and tested in accordance with
safety regulations
IEC 61010-1/EN 61010-1/VDE 0411-1 and
IEC 61010-2-032/EN 61010-2-032/
VDE 0411-2-032

. When used for its

intended purpose, safety of the operator, as
well as that of the instrument, is assured.
Their safety is however not guaranteed, if the
instrument is used improperly or handled
carelessly.

In order to maintain flawless technical safety
conditions, and to assure safe use, it is imperative
that you read the operating instructions
thoroughly and carefully before placing your
instrument into service, and that you follow all
instructions contained therein.

Observe the following safety precautions:

• Avoid excessive mechanical stress such
as impact and vibration, as well as high
temperatures and humidity, because this
may result in damage to the instrument.

• Do not use this instrument in close
proximity to acids, alkaline salts, organic
solutions, corrosive gases etc.

• Do not use this instrument in proximity to
devices which generate strong magnetic
and/or electrical fields, because this may
result in malfunctioning.

• Do not use this instrument in operating
environments where dust or splash
water occur.

Attention!

!

Do not perform measurements at
cables with voltages of greater
than 600 V AC.
Before using the instrument, test the
voltage of the electrical circuit to be
measured.

Do not perform measurements on bare
wires!
Do not subject the input and output
sockets to voltages of greater than

10 V AC.

The current clamp may not be used:

• If the device, the housing or the cable is
damaged

• If the battery compartment lid has been
removed

• For current values which are
impermissible high for the current clamp

• In the rain, with wet hands, in the
presence of splashing water or in moist
environments

2 Applications

The instrument is capable of measuring
direct and alternating current, and is
equipped with a connectable current clamp.

In the case of direct current measurement,
conventional current clamps are not capable
of performing accurate measurement in the
light current range due to influences resulting
from magnetization and geomagnetism. This
device is a current clamp measuring
instrument which is capable of very accurate
measurement of direct and alternating
current thanks to the use of highly sensitive
materials and a magnetization method.

Attention!

!

The specified maximum input
quantities may not be exceeded in
order to prevent damage to the
instrument and injury to the user:
voltage range: 600 V AC/DC,
current range: 10 A AC/DC.

3 Initial Start-Up

Batteries

Your instrument requires four 1.5 V batteries
(size AA) in accordance with IEC LR6.

Make sure that no battery leakage has
occurred before initial start-up, as well as
after long periods of storage. Continue to
inspect the batteries for leakage at short,
regular intervals.

If battery leakage has occurred, carefully and
completely clean the electrolyte from the
instrument with a damp cloth, and replace
the batteries before using the instrument.

If the “B” symbol appears at the LCD panel,
the batteries should be replaced as soon as
possible.

Battery Replacement

Attention!

!

Disconnect the current clamp from
the measuring circuit before opening
the device in order to replace the
batteries!

Remove the screw from the battery
compartment lid with a screwdriver. Push
the battery compartment lid in the direction
indicated by the arrow and remove it.
Remove the 4 batteries and replace them.
Return the battery compartment lid to its
original position and tighten the screw.

Do not use battery sets consisting of old and
new batteries, or batteries with different
brand names.
