About the Course:

This Digital Multimeter Operations for Aircraft Electronics microcredential trains Aircraft Electronics Technicians to understand and operate a digital multimeter for common electrical measurements used in aircraft electronics environments. 

Through immersive VR simulations, learners will practice setting up the multimeter, selecting the appropriate terminals and measurement modes, and using test probes to perform continuity, resistance, DC voltage, and current measurements. Learners will work with switches, circuit boards, wires, batteries, light bulbs, and resistors to understand how electrical measurements help verify circuit paths and component conditions. 

The course emphasizes proper probe placement, measurement-mode selection, electrical safety, accurate reading interpretation, and safe handling of the multimeter during electrical testing. 

Learning Objectives:

• Identify the major terminals, probes, selector dial, and functions of a digital multimeter. 
• Understand the purpose of the COM, Ω, and A terminals. 
• Select the appropriate measurement mode for continuity, resistance, voltage, and current. 
• Perform continuity tests on switches, circuit boards, and wires. 
• Understand the importance of ensuring circuits are powered OFF before continuity testing. 
• Measure resistance in wires, bulbs, resistors, and other components. 
• Perform DC voltage measurements on batteries and circuit boards. 
• Recognize reversed probe connections during voltage measurements. 
• Perform basic current measurements using the appropriate terminal and mode. 
• Interpret multimeter readings and identify basic electrical conditions. 
• Follow proper probe handling and electrical measurement safety procedures.
