Calaamadaha korantada ee tirada analooga ah ee ugu badan ee loo isticmaalo warshadaha waa in lagu gudbiyo tirada analoogga oo leh 4 ~ 20mA DC hadda.Sababta loo isticmaalo calaamadda hadda jirta ayaa ah in aysan sahlanayn in la farageliyo, iska caabinta gudaha ee isha hadda jirtana waa mid aan xad lahayn.Taxanaha iska caabinta fiilada ee wareegga ma saameynayso saxnaanta, waxaana lagu kala qaadi karaa boqollaal mitir labada lamaane ee caadiga ah.Xadka sare ee 20mA waa sababta oo ah shuruudaha aan qarxin: tamarta dhimbi ee ay sababtay jebinta hadda ee 20mA kuma filna inay shido gaaska.Sababta xadka hoose ee aan loo dejin 0mA waa in la ogaado xariiqda jaban: kama yaraan doono 4mA hawlgalka caadiga ah.Marka khadka gudbinta uu jabo cilad awgeed oo wareegga hadda uu hoos ugu dhaco 0, 2mA ayaa inta badan loo dejiyaa qiimaha qaylo-dhaanta khadka jaban.
