    Program Controlled Withstand Voltage Insulation Ground Tester Chapter I Safety Rules The contents of this manual are subject to change without notice. If the manual is not exhaustive, please contact us directly. Rules and matters that should be noticed before high voltage test! !! !! 1.1 General provisions Before using this tester, please read the instructions carefully to understand the operating procedures and related safety signs to ensure safety.
  • Page 3 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"...

The ground wire of the tester must be connected in accordance with regulations.
  • Page 5 Chapter II Introduction to Safety Regulations 1.1 The importance of testing In today's high consumer awareness, every manufacturer of electrical and electronic products must do its best to make the product safe. Each product must be designed to the best of its ability to prevent the user from being exposed to electric shock.
  • Page 6 the formal production test, because the product's safety is determined at the design and test stage. Although only a few samples are used for product design judgment, online testing during production should strictly require that all products must pass safety standards to confirm that no defective products will flow out of the production line.
  • Page 7 must be supplied, the current required by the instrument will be much larger than the current used in the DC test. This will increase the danger to the operator. 2.3.2 Characteristics of Direct Current (DC) Test During the DC withstand voltage test, the stray capacitance on the DUT is filled. The capacitive current caused by the DC withstand voltage test will drop to zero after the stray capacitance is filled.
  • Page 8 should be safer. The higher the insulation resistance value, the better the insulation of the product. The insulation resistance value measured by the insulation resistance test is the equivalent resistance value formed by various related networks connected between the two test points and their surroundings.
  • Page 9 times the rated input current of the appliance, and the resistance value of the contact point is still 100mΩ, and the test time is 60 seconds. Most of these are electrical appliances, which are dangerous, so the requirements for specifications are higher than general appliances. In the current safety regulations in the world, some specifically require that the contact resistance of the ground wire be measured first.
