🔍 Key Concepts

• Internal meter batteries and how they power the resistance (ohms) function • The purpose of zeroing or calibrating an analog ohmmeter before making measurements • Why selecting the proper range on a multimeter matters for accuracy and needle movement

💭 Think About

• Ask yourself: when measuring resistance with an analog meter, what must be adjusted so that the scale reads correctly before you connect it to any circuit? • Think about what would happen to your reading if the internal batteries are not accounted for or the needle is not set to the correct starting point. • Which option describes a normal, routine preparation step for using the ohms function on an analog multimeter, rather than disabling it?

✅ Before You Answer

• Identify which choices would actually prevent the meter from working on the ohms scale at all. • Consider which step is typically done with the test leads shorted together before using the resistance function. • Verify which answer combines both range selection and a basic calibration/zeroing step, as is standard practice with analog ohmmeters.
