Meters 030104a

Question 1

What four factors must be considered when selecting a meter?

Objective 2 Page 8

Answer 1

The electrical measurement required.

Whether the circuit is energized or de-energized.

The value you expect to obtain from the meter

Whether polarity is important in the electrical measurement.

Question 2

What does OL mean on a digital meter?

Objective 3 Page 15

Answer 2

Over the limit.

Question 3

Is an Ammeter connected in parallel or in series with the circuit?

Objective 4 Page 22

Answer 3

They should be connected in series.

Question 4

Why is it important to ensure a Voltmeter is set to the proper settings?

AC or DC

Objective 4 Page 17

Answer 4

If the Voltmeter is set to DC and used on an AC circuit it could indicate 0 Volts when in fact there is 120 Volts.

Question 5

Is a Voltmeter connected in a circuit in series or in parallel?

Objective 4 Page 18

Answer 5

In parallel or across the circuit component.

Question 6

Does an Ammeter have high or low resistance?

Answer 6

Low resistance.

Question 7

What can cause incorrect readings on an analog scale?

Answer 7

Parallax Error.

Reading an analog meter from the side and cause an inaccuracy.

Question 8

What type of meter is usually used to test conductor insulation?

Objective 1 Page 6

Answer 8

Megohmmeter

Specially designed ohmmeter that measures very high resistances.

Question 9

What would happen if you connected an ammeter into a DC circuit with the incorrect polarity?

Objective 2 Page 9

Answer 9

The needle would down scale or have no deflection.

Question 10

What is the difference between a linear and non-linear analog meter?

Objective 3 Page 13 & 14

Answer 10

Linear the divisions are equally spaced.

Non-linear the divisions are not equally spaced.
