Safety
This is a Safety Class 1 instrument
(provided with terminal for protective

 Before applying power, verify
that the correct safety precautions are
taken (see the following warnings). In

the instrument that are described under
Safety Symbols. Do not operate the

Warning
Before turning on the instrument, you
must connect the protective earth
terminal of the instrument to the
protective earth conductor of the (mains)
power cord. The mains plug must only be
inserted in a socket outlet with a
protective earth contact. Do not negate
the protective action by using an
extension power cord without a
protective grounding conductor.
Grounding one conductor of a
two-conductor outlet is not sufficient
protection.
Service instructions are for trained
service personnel. lb avoid dangerous
electric shock, do not perform any
service unless qualified to do so. Do not
attempt internal service or adjustment
unless another person, capable of
rendering 
Arst
 aid and resuscitation, is
present.
If you energize this instrument using an
auto-transformer (for voltage reduction)
make sure that the common terminal is
connected to the earth terminal of the
power source.
Whenever it is likely that the ground
protection is impaired, you must make
the instrument inoperative and secure 
It
against any unintended operation.
Do not operate the instrument in the
presence of flammable gases or fumes.
Operation of any electrical instrument in
such an environment constitutes a
