Quiz #3 (Lesson 4 - IA9)

It is the best instrument that can measure voltage, resistance and current. It is a must have measuring tool for every repair technician and electronic enthusiasts.

• Ammeter

• Voltmeter

• Multi-tester

• Push/Pull Rule

The needle-shape rod that moves over the scale of a meter. It is mechanically connected to the moving coil.

• Selector Switch

• Adjustment Screw

• Pointer

• Test probe

It is a series of marking used for reading the value of quantity.

• Selector Switch

• Scale

• Selector Knob

• Pointer

It is used to zero-in the pointer before measuring resistance.

• Pointer

• Zero Position Adjuster

• Range Selector Knob

• Zero-ohm Adjuster Knob

It is a voltage in the battery (dry cell or wet cell) or from a rectified power supply.
