What is a digital scale?
Explanation: The correct answer is B) A scale that displays weight in digital format. A digital scale is an electronic weighing device that displays the weight measurement digitally on a screen or display. It uses load cells and electronic components to convert the weight into an electrical signal and then processes it to provide a digital weight reading.
What units of measurement are commonly used by digital scales?
Explanation: The correct answer is D) Multiple units, such as pounds, kilograms, and ounces. Digital scales commonly provide weight measurements in multiple units to accommodate different user preferences or application requirements. They can display weights in units such as pounds (lb), kilograms (kg), ounces (oz), or even grams (g).
What is the advantage of using a digital scale over a mechanical scale?
Explanation: The correct answer is B) Better accuracy and precision. Digital scales offer better accuracy and precision compared to mechanical scales. The electronic components and load cells in digital scales provide more reliable and consistent measurements, allowing for precise weight readings. Mechanical scales, on the other hand, can be prone to errors and variations due to mechanical wear and tear or imprecise calibration.
What feature allows digital scales to tare the weight of containers or objects?
Explanation: The correct answer is A) Zeroing function. Digital scales often have a zeroing or taring function that allows you to subtract the weight of containers or objects placed on the scale. By pressing the tare or zero button, the scale resets the reading to zero, so only the weight of the added substance is measured.
What is the recommended practice when using a digital scale?
Explanation: The correct answer is D) Place the scale on a stable and level surface. It is important to place a digital scale on a stable and level surface to ensure accurate weight measurements. Uneven surfaces or vibrations can interfere with the scale's performance and accuracy. Additionally, following the manufacturer's guidelines for calibration and maintenance can help maintain the accuracy of the digital scale over time.
