On which DVOM scale would the reading 1.234 Ohms be displayed in the example?

• A. 2MΩ scale
• B. 20 Ω scale
• C. 200 Ω scale
• D. 20 kΩ scale

Answer: (A)

Understanding how resistance ranges affect display precision is key. A DVOM shows the measured resistance with a certain number of digits and decimal places, depending on the selected range. To display 1.234 ohms exactly, you need a range that provides three decimal places in its readout. In the example, the meter is set to the 2 megaohm range, which in that instrument format offers the necessary precision to show three digits after the decimal for low resistances. The same physical resistance would still be 1.234 Ω, but the 2MΩ range formats the display to present those three decimal places clearly. The smaller ranges would typically show fewer decimal places or align the digits differently, making 1.234 not as readily or accurately represented.
