Using Electronic Test Equipment, Part 1

5.0 1 Review SKU: ACCDA10CENDuration: 60 Minutes

Electronic instruments are designed to operate at specific levels of current, voltage, and resistance. The most basic type of electronic test equipment used by instrument technicians is the meter. This course focuses on the meters most commonly used to indicate the level of current, voltage, or resistance in a circuit or component. The meters covered in this course are the volt-ohm-milliammeter (VOM), the vacuum tube volt-ohmmeter (VTVM), the field effect transistor volt-ohmmeter (FETVOM), the digital multimeter (DMM or DVM), and the transistor tester.

  • Define meter sensitivity and explain how it influences the choice of a meter for a given application.
  • Read various linear and nonlinear meter scales.
  • List two ways in which meter leads can make contact with an electrical circuit or circuit component.
  • Identify the jacks on a typical VOM.
  • Identify the front panel controls on a typical VOM.
  • Given various function switch and range switch settings, correctly interpret VOM readings.
  • Using a typical VOM, perform the following measurements safely and correctly: DC current, DC voltage, and resistance.
  • Use a VOM to check a capacitor for continuity.
  • Identify the front panel controls on a typical VTVM.
  • Use a VTVM to measure voltage and resistance.
  • Identify the front panel controls on a typical FETVOM.
  • Use an FETVOM to measure current, voltage, and resistance.
