What part of the multimeter allows changing the function and scale?a.Test Probesb.Rangec.Range Selector Knobd.Zero Ohm Adjustment Knob

Break Down the Problem

1. Identify the parts of a multimeter listed in the question.
2. Determine which part is responsible for changing the function and scale.

Relevant Concepts

• A multimeter is an essential instrument for measuring electrical values such as voltage, current, and resistance.
• The function and scale can be adjusted to measure different electrical quantities accurately.

Analysis and Detail

1. Test Probes: These are the wires that connect the multimeter to the circuit being tested. They do not change the function or scale of the multimeter.
2. Range: This term generally refers to the measurement capability within a certain limit but is not a specific part of the multimeter.
3. Range Selector Knob: This is the component of the multimeter that allows the user to select different functions and measurement ranges (e.g., AC voltage, DC voltage, resistance).
4. Zero Ohm Adjustment Knob: This is used for calibrating the resistance measurement but does not change the function or overall scale.

Verify and Summarize

Based on the analysis, the part responsible for changing the function and scale of the multimeter is the Range Selector Knob. The other parts serve different purposes and do not fulfill this function.

Final Answer

c. Range Selector Knob
