1 Safety Precautions
The METRACLIP62 clip-on ammeter has been
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.
If used for its intended purpose, the safety of
the user and of the device is assured. The
device may only be operated by properly
trained personnel who are capable of recog-

nizing the dangers associated with the mea-
!
surement of electrical current and voltage.
Read the operating instructions completely and
carefully before using the device, and follow all
instructions included therein.
Meanings of symbols on the instrument:
Warning concerning a source of dan
(Attention: observe documentation!)
Continuous, doubled or reinforced
insulation
Indicates EC conformity
Applying the clip to dangerous active
conductors is permitted
The clip-on ammeter may not be used:
• If the battery compartment lid has been
removed
• If visible damage is apparent
• With damaged connector cables
• If it no longer functions flawlessly
• After lengthy periods of storage under
unfavorable conditions (e.g. humidity,
dust, temperature).

Attention!
!
Do not perform measurements in the
event of over-ranging!
Current which exceeds the measuring
range may not be measured.
Do not perform measurements at bare
wires!
Do not perform measurements at busbars!
Safe Handling
• The housing and the handles must be free
of dust, grease and moisture.
• The operator’s fingers may not be
extended beyond the safety collar during
measurement.
• Avoid excessive mechanical stress such
as impact and vibration, as well as high
temperatures, moisture and strong
magnetic fields.
•
The battery compartment lid must be
secured with the appropriate Phillips head
screw.
1.1 Special Features of the Hall Effect Sensor
Eliminating the influence of magnetization
The clip-on ammeter METRACLIP62 uses the
hall effect for its measurements. The characteristics of the hall effect are subject to a hys-
