Multimeters

Lesson Descriptions

This library consists of 5 interactive, on-line lessons. These lessons take approximately 30 to 45 minutes to complete.

These lessons were designed to provide training for persons working with electrical or electronic test equipment. These lessons present general information about multimeters.

Digital Multimeters


Description: This is the first lesson in the iKNOW™ Multimeters Library. The lesson presents the types of multimeters. The lesson describes the display area, function switch, and leads and jacks on a digital multimeter.

Prerequisites: None

Topics:

  1. Types of Multimeters
  2. Digital Display
  3. Function Switch
  4. Leads and Connectors
  5. Special Feature Buttons

Objectives:

  • Identify and describe the display area of a digital multimeter
  • Identify and describe the function switch on a digital multimeter
  • Identify and describe the leads/jacks on a digital multimeter

Analog Multimeters


Description: This is the second lesson in the iKNOW™ Multimeters Library. This lesson demonstrates various aspects of an analog multimeter, including how to adjust mechanical zero, how to interpret a reading on the voltage and resistance scales, and how to set the function and range switches.

Prerequisites: None

Topics:

  1. Zeroing
  2. Range Switch
  3. Voltage Scales
  4. Measuring Resistance
  5. Zero Ohms Adjust
  6. Summary

Objectives:

  • Adjust the mechanical zero of an analog multimeter
  • Interpret a reading on the voltage scale of an analog multimeter
  • Interpret a reading on the resistance scale of an analog multimeter
  • Given an expected measurement, set the function and range switches of an analog multimeter
  • Adjust the zero on the ohms scale of an analog multimeter

Multimeter Selection and Inspection


Description: This is the third lesson in the iKNOW™ Multimeters Library. This lesson trains the learner in the inspection of a multimeter, the steps that should be taken before using a multimeter, and how to perform a continuity check.

Prerequisites: Review of the lessons Digital Multimeters and Analog Multimeters is recommended.

Topics:

  1. Inspection and Safety
