Abstract
The utility model relates to the technical field of resistance testers, and particularly relates to a surface resistance tester. The surface resistance tester of the utility model comprises an instrument and hammer electrodes. The instrument is provided with a display screen and a key. The instrument is provided with a first electrode jack. Each hammer electrode comprises a body. The upper end face of the body is provided with a second electrode jack. In the testing process, the first electrode jack of the instrument is connected with the hammer electrodes, and then the hammer electrodes are placed onto the surface of a tested objected, and the key is pressed, so that the test result can be intuitively displayed on the display screen, and advantages of intuition, simple structure and convenient test can be realized.
Description
Technical field
The utility model relates to the resistance meter technical field, refers in particular to a kind of surface resistance tester.
Background technology
ESD(Electro-Static discharge) the meaning is " static release ".ESD is the subject with generation, harm and the electrostatic defending etc. of research static that has formed since mid-term in 20th century.Therefore, custom will be referred to as ESD for the equipment of electrostatic defending in the world, and Chinese is electrostatic impedor.
Static electricity on human body's guard system mainly contains the compositions such as ESD-preventive wrist strap, ankle band, heel band, working cloth, footgear, cap, gloves or fingerstall, has electrostatic leakage, neutralization and shields etc. multi-functional.
At present, the electronic product machining enterprise of numerous domestic, most to set up the ESD20.20 scheme according to Unite States Standard (USS), and it is nothing but to buy anti-static clothing and these simple ESD articles for use of wrist strap that the ESD of factory controls work, apart from the ESD20.20 standard, very large gap is arranged.A lot of enterprises often after having done meticulous preparation, but or because of the ESD problem are kept outside of the door when running into external big customer's on-site examination.
Therefore, based on the defective of the equipment of above-mentioned existing electrostatic defending, need to the equipment of existing electrostatic defending be improved.
The utility model content
The purpose of this utility model is to provide a kind of surface resistance tester for the deficiencies in the prior art, and the equipment that this surface resistance tester has solved existing electrostatic defending is existing: can't direct, open-and-shut understanding test result etc. defective.
For achieving the above object, the utility model is achieved through the following technical solutions: the surface resistance tester, comprise instrument, weight electrode, and wherein, instrument has display screen, button, and instrument has the first electrode jack; The weight electrode comprises body, and the body upper surface has the second electrode jack.
Described weight electrode comprises concentric circles weight electrode, elasticity concentric circles weight electrode, point-to-point weight electrode, 2 test weight electrodes.
Described body upper end is connected with hanging handle.
Described instrument has pilot lamp.
Described weight electrode has two.
The beneficial effects of the utility model are: during test, the first electrode jack of instrument is connected with the weight electrode, then the weight electrode is positioned over the surface of testee, push button, can demonstrate intuitively test result, very directly perceived, simple in structure, convenient test on display screen.
Description of drawings
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with accompanying drawing, the utility model is further described.
See Fig. 1, the utility model surface resistance tester comprises: instrument 11, weight electrode 12, and wherein, instrument has display screen 13, button 14, pilot lamp 15, and instrument has the first electrode jack; Weight electrode 12 comprises body, and the body upper end is connected with hanging handle 16, and the body upper surface has the second electrode jack 17.
During test, the first electrode jack of instrument is connected with weight electrode 12, then weight electrode 12 is positioned over the surface of testee, push button 14, can demonstrate intuitively test result on display screen 13, very directly perceived.
The factor that affects test result has: the temperature of test environment, humidity, and instrument error, test error is so each numeral shows that the sheet resistance value of surveying has deviation, as long as deviation does not cause that flash corresponding pilot lamp 15 left and right is exactly normal deviation.
The resistance range of anti-static product is generally 10
6-10
9Ω, some industry and product may be 10
5-10
12Ω, so the resistance range of anti-static product is larger, it is also to belong to anti-static product that resistance differs 1000 times, some deviations occur so test same product test result, as long as be all qualified in the electrostatic prevention scope.
The utility model is simple in structure, convenient test.
Certainly, the embodiment of the above, it is preferred embodiments of the present utility model, and unrestricted the utility model practical range, therefore all equivalences of doing according to the described structure of the utility model claim, feature and principle change or modify, and all should be included in the utility model claim.
Claims (1)
