Basic siv ntawm multimeter - ntsuas voltage
2.1 Voltage ntsuas
Thaum ntsuas DC voltage, thawj zaug ntxig cov xim dub thiab liab coj mus rau hauv qhov chaw nres nkoj thiab V muaj nuj nqi jack; Tom qab ntawd tig qhov hloov pauv mus rau V- lossis mV-txoj hauj lwm (Ceeb toom: Yog tias qhov ntsuas DC tsis paub meej, koj yuav tsum xub tig lub rotary hloov Tig rau V- txoj hauj lwm); Thaum kawg, txuas ob qhov kev xeem coj mus rau qhov sib npaug mus rau ob qhov kawg ntawm cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob. Lub sijhawm no, nws yuav tsum tau muab sau tseg tias qhov kev kuaj liab thiab xim dub coj mus rau qhov zoo thiab qhov tsis zoo ntawm cov khoom siv hluav taws xob lossis cov khoom siv hluav taws xob. Tom qab tus nqi ruaj khov, tus nqi ntawm qhov ntsuas DC voltage yuav tshwm rau ntawm LCD.
Txoj kev ntsuas ntawm AC voltage yog qhov pib zoo ib yam li ntawm DC voltage, qhov sib txawv yog tias lub pob qhov rooj yuav tsum tig mus rau V ~ lossis mV ~, thiab qhov hluav taws xob tsis muab faib ua qhov zoo thiab tsis zoo thaum ntsuas.
