connection to a PC or industrial personal computer.
11) Unless specially permitted, the instrument shell must not be opened; otherwise, internal circuits and parts may
be exposed, resulting in unnecessary damage.
12) If the instrument needs to be fixed in a test place, the protective ground wire should be installed between the
test place and instrument by the electrician with qualifications.
13) Take appropriate overload protection measures to avoid instrument damages or personal injuries caused by
overload voltage (arising from lightning, etc.).
14) If the instrument shell is opened, unnecessary parts must not be placed into the shell; otherwise, short circuiting,
instrument damages and even personal injuries may be caused.
15) Unless otherwise stated, the instrument is not subject to waterproof protection. Therefore, the instrument must
not contact with liquid to prevent damages and even personal injuries.
16) The instrument must not be placed in a place where mist can be easily produced. For example, if the instrument
is handled in an environment with temperature fluctuation, hazards such as electric shock may be caused by water
drops produced on the instrument.
2.2.4 Operation Precautions
1) The instrument operator must have certain professional and technological knowledge, good psychological
quality and emergency response capability.
2) Refer to relevant requirements in “
2.2.7 Transportation
” before handling or transporting the instrument.
3) Allergic substances (such as nickel) are produced inevitably during instrument production. If the operator shows
any allergic symptom (such as rash, frequent sneezing, red eye, breathing difficulty, etc.), immediately seek
medical help to eliminate the symptoms.
4) Refer to relevant requirements in “ 2.2.8 Waste disposal/environmental protection
” of this section before
removing and disposal of the instrument.
5) RF instruments may result in high-intensity electromagnetic radiation. The pregnant women and operators with
heart pacemaker must be protected particularly. If the degree of radiation is high, take appropriate measures to
remove the radiation source so as to prevent personal injury.
6) If a fire occurs, toxic substances will be released by the damaged instrument. In this case, the operator should
wear appropriate protective equipment (such as the protective mask and clothing) for protection.
7) The laser product should be marked with warnings according to the laser category, as personal injuries may be
caused as a result of laser radiation and high electromagnetic power of such products. 8) If the instrument is
integrated with any laser product (such as a CD/DVD drive), no additional function should be added, except the
settings and functions described in the manual, in order to prevent personal injuries caused by laser beams.
8) The electromagnetic compatibility should conform to the EN55011/CISPR11, EN55022/CISPR22 and
EN55032/CISPR32 standards.
-Class A equipment:
Applicable to any place except in residential areas and a low-voltage power supply environment.
Note: Class A equipment is suitable for the industrial operating environment. As wireless communication
disturbance may be caused to residential areas, the operator should take appropriate measures to reduce disturbance.
-Class B equipment:
It is applicable to the residential area and low-voltage power supply environment.
2.2.5 Maintenance
1) The instrument chassis must be opened by an authorized operator who has received special technical training.
The power cord should be disconnected before operation, so as to avoid instrument damages and even personal
injuries.
