Question 1

When using an oscilloscope to make measurements, the first step is _____.&#10;A) initializing the scope&#10;B) connecting the probe to the circuit&#10;C) connecting the ground lead to circuit ground&#10;D) compensating the probe

Accepted Answer

Initializing the scope is the first step to ensure that the oscilloscope is set up and ready for use before making any connections to the circuit or compensating the probe.

Question 2

Time is measured ____ on the oscilloscope graticule.&#10;A) vertically&#10;B) horizontally&#10;C) diagonally&#10;D) in three dimensions

Accepted Answer

Time is measured horizontally on the oscilloscope graticule, with the horizontal axis typically representing time and the vertical axis representing voltage or current.

Question 3

A digital multimeter can measure voltage, current, and resistance.

Accepted Answer

A digital multimeter is a versatile tool that can measure multiple electrical properties including voltage, current, and resistance.

Question 4

Which technique is used to measure small amounts of current using a clamp-on ammeter?&#10;A) winding the conductor around one jaw of the ammeter&#10;B) placing the conductor between the jaws of the ammeter&#10;C) placing the conductor underneath the jaws of the ammeter&#10;D) winding the conductor around the main body of the ammeter

Accepted Answer

Winding the conductor around one jaw of the clamp-on ammeter increases the magnetic flux, thereby enhancing the ammeter's ability to detect smaller currents. This technique effectively multiplies the measured current, allowing for more accurate readings of small currents.

Question 5

A megohmmeter can be used to conduct resistance tests to ground.

Accepted Answer

A megohmmeter, also known as a megger, is specifically designed to measure high resistance values, typically in the range of megohms, and is commonly used to conduct insulation resistance tests, including resistance tests to ground.

Question 6

How many basic types of oscilloscope probes exist?&#10;A) one&#10;B) two&#10;C) three&#10;D) four

Accepted Answer

There are three basic types of oscilloscope probes: passive probes, active probes, and current probes.

Question 7

A voltage tester is more accurate in measuring voltage than a digital multimeter.

Accepted Answer

A digital multimeter is generally more accurate and versatile in measuring voltage, as well as other electrical parameters, compared to a basic voltage tester, which is primarily designed for detecting the presence of voltage.

Question 8

In which section of an oscilloscope is the intensity control found?&#10;A) horizontal section&#10;B) vertical section&#10;C) display section&#10;D) trigger section

Accepted Answer

The intensity control is found in the display section of an oscilloscope. It adjusts the brightness of the trace on the screen.

Question 9

The clamp-on ammeter can be used to measure both large and small amounts of current.

Accepted Answer

Clamp-on ammeters are designed to measure a wide range of currents, from very small to very large, without needing to make physical contact with the conductor or interrupt the circuit.

Question 10

Before using a digital multimeter, you should ____.&#10;A) check the ground&#10;B) break the circuit&#10;C) compensate the probes&#10;D) inspect the meter and probes

Accepted Answer

Inspecting the meter and probes ensures they are in good condition and safe to use, which is a fundamental safety practice before using a digital multimeter.

Question 11

In which section of an oscilloscope is the variable sec/div control found?&#10;A) horizontal section&#10;B) vertical section&#10;C) display section&#10;D) trigger section
