6)
The outlet should be kept clean and tidy, and the plug and outlet should be contacted properly
and firmly.
7)
The outlet and power cord should not be overloaded; otherwise, fire or electric shock will be
caused.
8)
Unless otherwise permitted, the instrument enclosure should not be opened; otherwise, the
internal circuits and components will be exposed, causing unnecessary damage or injury.
9)
If the instrument needs to be fixed at the test site, a protective ground wire should be installed
between the test site and the instrument by a qualified electrician.
10)
Appropriate overload protection measures should be taken to avoid instrument damage or
personal injury caused by overload voltage (in the event of lightning for example).
11)
When the instrument enclosure is opened, do not place other foreign objects into the case;
otherwise a short circuit may be easily caused, resulting in instrument damage or personal injury.
12)
Unless otherwise stated, the instrument not subject to waterproof treatment should not be
exposed to liquid, lest instrument damage or even personal injury should occur.
13)
Do not place the instrument in an environment that is prone to fogging. For example, if the
instrument is moved in an alternate cooling and heating environment, water droplets will be formed
on the instrument, causing electric shock and other hazards.
1.2.3 Operation precautions
1)
The instrument operator should have certain professional technical knowledge, good
psychological quality and certain ability of emergency response.
2)
Before moving or transporting the instrument, please refer to the relevant instructions in “2.2.7
Transport” of this section.
3)
If the instrument operator suffers from allergy (e.g. rash, frequent sneezing, red eyes, or
breathing difficulty) during operation due to the inevitable use of substances (such as nickel) that
may cause personal allergy in the process of production of the instrument, please seek medical
advice promptly to find the cause and resolve the symptom.
4)
Before disassembling the instrument for disposal, please refer to the relevant instructions of
“2.2.8 Disposal/environmental protection “of this section.
5)
As the radio frequency instrument will produce a high level of electromagnetic radiation, a
pregnant woman and an operator with a heart pacemaker need special protection. If the radiation
level is high, appropriate measures can be taken to remove the radiation source to avoid personal
injury.
6)
The instrument will release toxic substances once catching fire. For this reason, the operator
should wear suitable PPEs (such as protective mask and cloth), just in case.
7)
EMC grade: instruments with option H90 shall meet the requirements of 3.9.2 in GJB
3947A-2009, and those without H90 meet the requirements of 3.9.1 in GJB 3947A-2009.
1.2.4 Maintenance
1)
Other persons than those authorized technicians who have received professional technical
trainings are not allowed to open the instrument case. Before performing such operation, it is
necessary to disconnect the power cord to prevent instrument instrument or even personal injury.
2)
The instrument should be repaired, replaced or maintained by a professional electronic
engineer designated by the manufacturer. The replaced and maintained part should be subject to
safety test to ensure safe use of the product in the future.
1.2.5 Battery or power module
1) The instrument has power consumption of 400W maximum, supply of 50Hz - 60Hz and single
phase of 110V or 220V adaptive. The steady-state power conditions meet the
requirements of 3.5.1.3 in GJB3947A-2009, and the persmissible range of steady-state voltage
and frequency is
10% and
5% of the rating, respectively.
