It means it can measure in order to 20 volts away from direct current (DC) electricity
That’s called direct-current
2) Circulate the latest arrow this points to 20. The brand new “DCV” characters stand for direct current current. This is voltage that triggers stamina so you’re able to move in one guidance. This is such as the batteries on the car, mobile, or any kind of. He has a terrible critical and you will an optimistic terminal. The fresh new electrons just is born the newest negative critical for the confident critical.
3) Connect the latest black sample head connect toward input jack that consist next to the label “COM”. ” COM ” is short for com mon ground. This is the negative type in. This basically means, that’s where it wants an excess of electrons, to manufacture they adversely energized.
Another stop of the wire try linked to the yellow test lead probe
4) Link the new purple sample head plug to the jack you to lies next to the name “V?mA”. The newest “V” signifies volts. The ? (ohm icon) is for computing electronic opposition, and you can “mA” means milliamps, and therefore steps small electronic currents.
