Electrical Troubleshooting Tools: Ohmmeter

• The ohmmeter is used to measure the resistance between two points in a circuit and to inspect for continuity and short circuits.

  CAUTION:

  • Do not connect the ohmmeter to any circuit where voltage is applied. This will damage the ohmmeter.
• When using the tool for connecting the ohmmeter to the female terminal, the lead wire of the ohmmeter should be connected to the tool first and then connected to the female terminal. This will help to avoid deformation of the female terminal opening due to excessive force.
