The saxnaanta ee cabbirka elektarooniga ah ayaa qeexaya muujinta u dhow qiimaha la tilmaamay waa qiimaha saxda ah ee calaamadda cabbiraadda. Si kastaba ha ahaatee, 10.0 volts ayaa lagu qiyaasay miisaan 100-V oo isku mid ahvoltmeter waxa uu akhrin karaa inta u dhaxaysa 7 V iyo 13 V, ama ± 30% ee akhrinta dhabta ah, halka mitirkuna uu farsamo ahaan ka hooseeyo.

Intaa waxaa dheer, waa maxay saxnaanta multimeter-ka dhijitaalka ah?

Tusaale ahaan, an saxnaanta of ± (2%+2) macnaheedu waa in akhrinta 100.0 V on the multimeter wuxuu noqon karaa 97.8V ilaa 102.2 V. Isticmaalka a DMM oo ka sarreeya saxnaantaogolaanaya tiro badan oo codsiyada. dc aasaasiga ah saxnaanta ka baxsan gacanta Fluke multimeter-ka dhijitaalka ah waxay u dhaxaysaa 0.5% ilaa 0.025%.

Sidoo kale, waa maxay tirinta multimeter-ka dhijitaalka ah? A 3.5-god multimeter ayaa soo bandhigi doonadigital akhrinta ka kooban saddex lambar oo ka bilaabmaya 0 ilaa 9, oo lagu daray 1 ama 0 nambar badhkii; yacni, akhrinta sidamultimeter waa inta u dhaxaysa 0.001-1999.

Halkan, waa maxay kala duwanaanta saxnaanta?

Saxnimada, Qaraarka iyo Range(Qeexid) Saxnimada waa awoodda cabbirka oo ku siman qiimaha dhabta ah ee tirada la cabbirayo. Xalku waa tirada lambarrada muhiimka ah (meelaha tobanlaha ah) ee qiimaha si la isku halleyn karo loo cabbirayo. Range ma inta ay le'eg tahay qiimaha lagu cabbiri karo.

Waa maxay macnaha RDG sax ahaan?
