Multimeter Basics Flashcard

Front

What should you ensure when measuring high AC voltage?

Back

The integrity of your multimeter and test leads.

Front

What should you do if unsure about the voltage you're measuring?

Back

Start with the highest setting and work down.

Front

What safety precaution should be taken when testing for continuity?

Back

The device should not be powered.

Front

What is the primary source of DC voltage in most devices?

Back

Batteries.

Front

How should you set the dial when measuring a known voltage?

Back

To the next number up from the maximum voltage.

Front

What is a multimeter?

Back

A device used to measure voltage, current, and resistance.

Front

What does the resistance mode on a multimeter measure?

Back

It measures how much a component resists the flow of electric current.

Front

What is the difference between AC and DC voltage?

Back

AC voltage alternates direction, while DC voltage flows in one direction.

Front

Why is it important to start with the highest setting on a multimeter?

Back

To prevent damage to the multimeter and ensure accurate readings.

Front

What is continuity testing?

Back

A method to check if there is a complete path for current to flow.
