🔍 Key Concepts

• Difference between a basic digital multimeter and an advanced multifunction multimeter • Which instruments in the illustration are specialized testers (insulation testers, clamp-on ammeters, probes) rather than general-purpose meters • Visual cues of a meter that has many additional built-in functions (extra buttons, complex display, multiple modes)

💭 Think About

• Look at each choice and ask: does this device mainly measure volts, ohms, and current, or is it designed for one special task like insulation testing or clamping around a conductor? • Compare the simplicity/complexity of the front panel among the options that look like multimeters. Which one clearly shows many extra controls and modes along with a digital readout? • Which illustrated meter combines the look of a multimeter (V–Ω–A ranges) with a large digital/graphical display instead of a simple numeric window?

✅ Before You Answer

• Confirm that the instrument you select has clear V and Ω measurement ranges labeled on the front. • Verify that it has a digital display, not an analog pointer/needle scale. • Check that it obviously includes multiple extra functions or modes beyond basic voltage, resistance, and current measurements (numerous buttons, menu keys, or complex screen).
