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 has been manufactured and tested in
accordance with safety regulations IEC 61010–1:2001/
DIN EN 61010–1:2001/VDE 0411–1:2002. If used for its intended
purpose, safety of the operator, as well as that of the instrument, is
assured. However, safety cannot be guaranteed if the instrument is
used improperly or handled carelessly.
In order to maintain flawless technical safety condition, 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
•
The instrument may only be operated by persons who are capable
of recognizing contact hazards and implementing appropriate
safety precautions. Contact hazards exist anywhere, where volt-
ages 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 terminals (3), (4), (5), (6) and ground
is equal to 600 V category II or 300 V category III.
•
The instrument may only be used for current measurement in power sys-
tems if the electrical circuit is protected with a fuse or a circuit breaker
with a rating of up to 20 A. In order to conform to the CAT requirements,
two fuse links have been fitted for the ranges mA und A.
•
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 condi-
tion, e.g. no damage to insulation, no interruptions in cables or
plugs etc.
