Safety Features and Precautions
You have selected an instrument which provides you with a
high level of safety.
This instrument fulfills the requirements of the applicable
European and national EC guidelines. We confirm this with
the CE marking. The relevant declaration of conformity can
be obtained from GMC-I Messtechnik GmbH.
The analog-digital multimeter is manufactured and tested in
accordance with safety regulations IEC 61010–1:2010/
DIN EN 61010–1:2010/VDE 0411–1:2011. 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.
In the interest of your own safety and in order to protect the
instrument, the multimeter is equipped with an automatic
socket blocking mechanism. This mechanism is linked to the
function selector switch and only allows access to those
jacks which are actually required for the selected function. It
also prevents the user from turning the selector switch to
impermissible functions after the measurement cables have
already been plugged in.
Observe the following safety precautions:
•
The instrument may only be operated by persons who
are capable of recognizing contact hazards and taking
the appropriate safety precautions. Contact hazards exist
anywhere, where voltages of greater than 33 V
RMS
may
occur.
•
Avoid working alone when taking measurements which
involve contact hazards. Be certain that a second person
is present.
•
Maximum allowable voltage
between any of the connector
jacks and earth
is 600 V, category III
. Nominal voltage at
the system may not exceed 600 V. Voltage measurement
may only be performed with the selector switch set to the
V= or the V~ position.
•
Be prepared for the occurrence of unexpected voltages
at devices under test (e.g. defective devices). For
example, capacitors may be dangerously charged.
•
Make certain that the measurement cables are in flawless
condition, e.g. no damage to insulation, no interruptions
in cables or plugs etc.
•
No measurements may be made with this instrument in
electrical circuits with corona discharge (high-voltage).
