How often should I calibrate my weighing machine?
The calibration frequency depends on the type of scale and usage. Digital scales generally require less frequent calibration, but it's recommended to check and calibrate them periodically.
Can weighing machines measure body fat percentages?
Some advanced weighing machines, known as body fat scales, use bioelectrical impedance to estimate body fat percentages. However, their accuracy may vary.
What is the difference between digital and analog weighing machines?
Digital scales provide precise readings in digits, while analog scales use a needle or pointer. Digital scales are often considered more accurate and easier to read.
