  1. Turn the dial to a higher voltage setting - Try the “200” setting in the DC voltage (V⎓) section. This will handle voltages up to 200V.

  2. Check your connections - Make sure:

    • The black probe is firmly in the “COM” port
    • The red probe is firmly in the “VΩmA” port
    • You’re making good contact with the battery terminals

  3. Verify the battery orientation - Make sure you’re touching:

    • Black probe to the negative (-) end of the battery
    • Red probe to the positive (+) end of the battery
