Multimeter Introduction
What is a Multimeter
A multimeter is an indispensable electrical test tool used by a wide variety of industrial and commercial technicians for instant installation maintenance and troubleshooting tasks
True/False: The arrangement and location of functions may vary from meter to meter
True
What does the digital display show?
the numerical value of the measurement being made
What color goes on the positive side of the circuit or power source?
Red
How is the flow of electric charge measured
Without really understanding multimeter settings and following proper measurement procedures, improper multimeter use can cause:
Inaccurate readings
Multimeter damage
Equipment damage
Personal injury or death
Hazardous situations for others
When looking at a multimeter, what color is commonly used to show the main function of the multimeter.
Black or white
What does a measurement consist of
both numerical value and the symbol identifying the function selected.
What color does the negative charge go on the power source or circuit.
black
Current Flow and Conventional Current assumes that current flows through which side of the battery?
Positive
True/ False: Industrial technicians use a wide variety of tools to make measurements. A multimeter is often one of them, even if some tasks require specialized electrical test tools. A general-purpose multimeter will usually do the trick. Understanding the broad range of capabilities of a multimeter will help you select the best tool for an application.
True
When using the multimeter, what button can you press to show the measurement of the screen even if the object that is being measured is no longer touching the multimeter?
The "Hold" button
What color does the display show when the measurement is accurate?
Green
Where do you typically plug the accessories for a multimeter.
The bottom
Election flow is when electrons flow out of which side of the battery
Negative
What two or three main measurements does the multimeter measure
voltage
resistance
current
