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 GOSSEN METRAWATT 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 instru-
ment 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 plac-
ing your instrument into service, and that you follow all instructions contained therein.
For your safety, as well as for protection of your multimeter, the instrument is
equipped with a miniature circuit breaker for the 15 A current measuring range.
Observe the following safety precautions
•
The instrument may only be operated by persons who are capable of recog-
nizing contact hazards and implementing 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 terminals (3), (4), (5), (6) and ground is equal to
300 V, category II.
•
The current measuring range A is equipped with a magnetic circuit breaker.
Max. allowable voltage at the meas. circuit (= miniature circuit breaker nominal
voltage) is equal to 240 V~ (AC) and 50 V
(DC) against earth in the “mA”
and “A” ranges.
•
The instrument may only be used for current measurement in power systems if the
electrical circuit is protected with a fuse or a circuit breaker with a rating of up to
20 A, and if nom. voltage at the system does not exceed 240 V~ (AC) or 50 V
(DC).
In order to conform to the CAT requirements, an additional slow-blowing fuse link
(T16A/500V) has been fitted in series with the miniature circuit breaker which can
only be replaced by service personnel once it is tripped.
•
Be prepared for the occurrence of unexpected voltages at devices under test
(e.g. defective devices). For ex., 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).
•
Special care is required when measurements are made in HF electrical
circuits. Dangerous pulsating voltages may be present.
•
Measurements under moist ambient conditions are not permitted.
