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
EU guidelines and national regulations. We confirm this
with the CE marking. The relevant declaration of conformity
can be obtained from GMC-I Messtechnik GmbH.
The instrument is manufactured and tested in accordance
with safety regulations IEC 61010–1:2010/DIN EN 61010–
1:2011/VDE 0411–1:2011. When properly used, 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 instru-
ment 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 taking
the appropriate safety precautions. Contact hazards
exist anywhere, where voltages of greater than 33 V may
occur (effective value).
• Avoid working alone when taking measurements which
involve contact hazards. Be certain that a second person
is present
.
• The maximum allowable voltage between any given connector
jack (1) and earth is equal to 600 V CAT II.
• Be prepared for the occurrence of unexpected voltages
at devices under test (e.g. defective devices). For exam-
ple, capacitors can be dangerously charged.
• Make certain that the measurement cables are in flaw-
less condition, e.g. no damage to insulation, no interrup-
tions 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
allowable.
• Be absolutely certain that the
measuring ranges are not
overloaded beyond their allowable capacities
. Limit val-
ues can be found in the table “Measuring Ranges” in
chapter 14 "Characteristic Values".
