EPC 1092 - Multi-Meters


Clock Hours: 42

Delivery Mode
on-ground

Prerequisites: EPC 1080 Residential Wiring Basic and Lab

Course Description:
This course teaches the student how to use their multi-meter, and which Category meter (CAT I, CAT II, CAT II) to use for the application they are in.

Student Learning Outcomes:
  • List the personal protective equipment (PPE) required when using a DMM.
  • List the four overvoltage installation categories and an example of each.
  • Identify the maximum voltage and current listings on DMM terminals and test leads.
  • Test condition of DMM test leads and fuse.
  • Identify common DMM abbreviations.
  • Identify common DMM symbols.
  • Define DMM terms including an abbreviation and/or symbol.
  • Identify common prefixes used with electrical/electronic values.
  • Identify the resolution of a DMM reading.
  • Determine maximum readings with different range settings.
  • Determine the value of a bar graph measurement.
  • Identify ghost voltage displayed.
  • List the ranges of the voltage, current, and resistance scales on the DMM.
  • Set the DMM to record minimum and maximum measurements.
  • Set the DMM to display the difference between a reference measurement and subsequent measurements using the Relative mode.
  • Set the DMM to automatically subtract the resistance of the test leads when taking low-resistance measurements.
  • Measure AC voltage.
  • Determine branch circuit voltage drops.
  • Use Relative mode with AC voltage measurements.
  • Convert RMS, average, peak, and peak-to-peak voltage values.
  • Measure DC voltage.
  • Determine DC circuit polarity.
  • Use Relative mode with DC voltage measurements.
  • Use MIN MAX Recording mode with DC voltage measurements.
  • Test continuity.
  • Use RANGE setting to display resistance measurement ranges.
  • Measure current in a series branch of circuit.
  • Use MIN MAX Recording mode to monitor changes in current.
  • Measure line frequency on an AC circuit.
  • Convert capacitance values in farads, microfarads, and Nano farads.
  • Measure capacitance using Capacitance Measurement mode.
  • Test capacitor using Resistance mode.
  • Identify the acceptable resistance range of good test leads.
  • Interpret key information listed in DMM specifications.
