D1-DVOM/ITS Tech SC-DV-2700-I

Prerequisites: Personal experience with Volt Ohm Meter Desired

Course Description: The class is designed to improve technicians’ understanding of basic DVOM functions. Students will be working with a Digital Volt Ohm Meter (DVOM) to learn its safe usage. Students are encouraged to bring their own meters for comparison. Course includes both lecture and lab experiences.

Course Benefits: The benefit of this course is designed to expose the students to all capabilities of the DVOM. Students will gain knowledge about the functions of the various DVOM screens using their own meters as an example. Fluke meters are emphasized as a base, with other meters including specialty meters such as the fluke 1587, which is capable of safely testing the High Voltages in the Electric and Hybrid Vehicle System.

What You Will Learn:

• Use of the functions of the DVOM
• Proper hookup of the DVOM for each function
• Interpreting basic DVOM digital displays
• Voltage measurements
• Resistance measurements
• Amperage measurements
• Frequency measurements
• Min/Max, diode and other special functions
• Identifying open and short circuits

Equipment Requirements:

• Classroom with computer/projector
• PowerPoint presentation
• Student workbook for each technician
• Master included with instructorís set includes PowerPoint and lab exercises

Fluke meters are emphasized as a base, with other meters including specialty meters such as the fluke 1587 which is capable of safely testing the High Voltages in the Hybrid Vehicle System (one for every two techs minimum with techs encouraged to bring their own).

Demonstration pieces for each DVOM mode (ie: resistors, TPS, knock sensors or frequency modulator, AC & DC voltage sources rectifier bridge/diodes. Jumper wires and simple circuits to practice voltage drop, amperage and short/open circuit examplesócan use vehicle if available).
