Dimensions thiab Khoom siv
Daim ntawv thov
Xov tooj, moos, khoom siv kho mob, cov khoom siv digital, cov khoom ua si, cov khoom siv ua haujlwm, Nco ntsoov lub computer, microwave ncu, cua txias, khoom siv hluav taws xob hauv tsev, tsis siv neeg tswj cov khoom siv.
Daim Ntawv Ceeb Toom
1. Thov tsis txhob kov cov khoom siv tes liab qab, vim tias electrode tej zaum yuav corroded.
2. Tsis txhob rub cov hlau lead ntau dhau vim tias cov hlau tuaj yeem tawg lossis qhov taw tes soldering tuaj yeem tawm.
3. Cov circuits siv transistor switching, Circuit Court constants rau heft ntawm lub transistor yog optimally xaiv kom ruaj khov, yog li thov ua raws li nws thaum koj tsim ib lub voj voog.
4. Sib nqus sounders yog tsav los ntawm ib qho input zaus, cov yam ntxwv zaus muab tau tsuas yog thaum thov 1/2 lub luag haujlwm square yoj (Vb-p).Cov neeg siv kawg yuav tsum paub qhov tseeb tias cov yam ntxwv ntawm zaus yuav hloov pauv ntau yam nrog rau ntau yam nthwv dej, xws li sine yoj, square yoj (Vb-p) lossis lwm yam nthwv dej.
5. Thaum siv lwm qhov hluav taws xob ntau dua li qhov pom zoo, cov yam ntxwv ntawm zaus kuj yuav raug hloov.
6. Thov khaws cia kom zoo rau qhov muaj zog sib nqus thaum koj khaws cia, hloov mus thiab mounting.
Soldering Thiab Mounting
1. Thov nyeem ntawm HYDZ specification, yog hais tias yuav tsum tau soldering tivthaiv.
2. Kev ntxuav ntawm cov khoom siv yog tsis tsim nyog, vim nws tsis scaled.
3. Thov tsis txhob npog lub qhov nrog daim kab xev lossis lwm yam teeb meem, vim qhov no yuav ua rau kev ua haujlwm tsis zoo.
