Safety Precautions
1.1
General
The
METRALINE PAT
test instrument has been
manufactured and tested in accordance with
the following safety regulations:
•
DIN EN 61010-1 (VDE 0411, part 1),
“Safety Requirements for Electrical
Equipment for Measurement, Control,
and Laboratory Use, General Require-
ments”
•
Interference immunity in accordance with
DIN EN 61326, “Electrical equipment for
control technology and laboratory use –
EMC requirements”
Safety of the inspector, as well as that of the
test instrument and the device under test, is
only assured when used for intended pur-
pose.
Read the operating instructions carefully and
completely before placing your test instrument
into service. Follow all instructions contained
therein. Make sure that the operating instructions
are available to all users of the device.
Tests may only be performed by a qualified elec-
trician, or under the supervision and direction of a
qualified electrician. The user must be instructed
by a qualified electrician concerning performance
and evaluation of the test (see also training semi-
nars listed at www.gossenmetrawatt.com).
In order to maintain safety and ensure safe oper-
ation, the user must observe the following warn-
ings:
Observe the warnings on the test instrument
and on the mains adapter cables!
Warning: Voltage!
The instrument may only be con-
nected to electrical systems with a
maximum of 230 V which comply
with applicable safety regulations
(e.g. IEC 60346, VDE 0100) and are
protected with a fuse or circuit
breaker with a maximum rating of
16 A.
Warning: Voltage!
Measurements within electrical sys-
tems are prohibited.
Attention!
!
Before connecting a DUT,
absence of voltage in the protective
conductor at the connection must be
verified by touching the finger con-
tact. The LED must not blink. It must
also be verified that < 30 V appears
in the connection menu.
Warning: Voltage!
No measurements may be con-
ducted on unfused measuring cir-
cuits.
The test instrument may no longer be used if
safe operation is not possible, e.g. due to
–
Visible damage
–
Improper storage
–
Improper transport
–
Phase indicator lamp failure
–
Failure of measuring functions etc.
The test instrument must be removed from
service immediately and secured against
inadvertent start-up.
Attention!
!
Protective conductor resistance and
touch current measurements in elec-
trical systems are only permitted
under certain conditions and after in-
stalling appropriate hazard warnings.
Warning: Voltage!
It must be observed that high volt-
ages can occur at test objects, e.g.
due to charged capacitive circuits.
Warning: Voltage!
Do not touch the insulation measur-
ing instrument’s test probes during
insulation resistance or equivalent
leakage current measurements.
