1.3 Test environment
1.3.1 Working position
When operating the instrument, make sure that the instrument is placed in a place where
ordinary personnel cannot touch it at will. If this is not possible due to production line
arrangements, the test area must be isolated from other facilities and a "high-voltage test work
area" must be marked. If the high-voltage test area is very close to other work areas, special
attention must be paid to safety. During the high voltage test, it must be marked "Danger! During
high voltage test, non-workers should not approach."
1.3.2 Input Power
The tester must be well grounded, and the ground wire must be connected before testing to
ensure the safety of the operator. The test area power supply must have a separate switch
installed at the entrance to the test area to ensure that everyone can identify it. In the event of an
emergency, the power can be turned off immediately.
1.3.3 Workplace
Use a workbench with non-conductive material where possible. Do not use any metal between
the operator and the test object. The position of the operator must not be across the object to be
operated and adjusted. If the volume of the object to be measured is small, place the object to be
tested in a non-conductive box as much as possible.
The test site must be kept tidy and clean at all times, and must not be cluttered. Place unused
instruments and test leads in a fixed position. Make sure that all personnel can immediately
separate the test object, test object and test object.
The test area and the surrounding air must not contain flammable gases, and the tester should not
be used near flammable materials.
1.4 Operator regulations
1.4.1 Qualification of personnel
The voltage and current output by the tester are sufficient to cause personal injury or fatality
during electric shock due to incorrect operation, and must be used and operated by qualified
personnel.
1.4.2 Safety Code
Operators must be educated and trained at all times to understand the importance of various
operating rules and operate the tester in accordance with safety rules.
1.4.3 Clothing regulations
Operators are not allowed to wear clothes with metal decoration or metal bracelets and watches,
as these metal accessories are likely to cause accidental electric shock. The consequences are
