The circuit tester is a simple test instrument which only shows whether the circuit is intact or whether there is a break . 電路導通器是一種簡單的量測儀表,它只能檢查電路的通斷狀況。
Outlet circuit testers and similar indicating devices 輸出回路測試儀和類似的指示裝置
Structure of system software of gh3183 integrated circuit tester 3183集成電路測試儀系統(tǒng)軟件的結構
An in - circuit tester tests a digital ic using the ic ' s truth table 在線測試設備采用真值表來測試數(shù)字集成電路。
The first test an in - circuit tester performs is a shorts - and - opens test 在線測試完成的第一項測試任務就是短路、開路測試。
After performing the shorts and opens test , the in - circuit tester tests each component on a pcb assembly one at a time 在線測試完成的第一項測試任務就是短路、開路測試。
After performing the shorts and opens test , the in - circuit tester tests each component on a pcb assembly one at a time 短路、開路測試完成以后,在線測試儀需要在同一時間對印刷電路板上的每一個器件進行測試。
These testers cost less than in - circuit testers , and some manufacturers claim that tests run faster on mdas 這些測試設備所需要的費用要比在線測試設備少,而且有些制造商還宣稱在生產(chǎn)缺陷分析設備上,測試速度進行的更快。
In - circuit testers can now also test for solder opens on surface - mounted devices ( smds ) , a common manufacturing defect on boards with smds 對于表面安裝設備來說,焊接開路是一個很普遍的制造缺陷,在線測試設備可以將其測試出來。
For complex boards or boards that aren ' t tested with an in - circuit tester , most companies perform a functional test before final assembly 對于復雜的電路板或者沒有經(jīng)過在線測試的電路板而言,很多公司在最后裝配之前進行功能測試。
