#1 Every time a digital scale is moved it needs to be calibrated. Initializing the scale resets the internal parts allowing the scale to find the correct “zero” weight and ensure accurate readings. If the scale is moved and you do NOT calibrate it, you are likely to see fluctuations in your weight.

Put your scale on a hard, flat surface Linoleum, vinyl, carpet, and other softer flooring can cause small variations in weight depending on how much cushion there is. EatSmart bathroom scales have four precision sensors. To maximize accuracy, these sensors need to be placed on a hard, flat surface.

Weigh two objects together.

1. Place one object on the scale. Note the weight. Take it off and let the scale even back out.
2. If it matches, the scale is accurate. If it doesn’t, try it again and see if it is off by the same number. If it is, it might be that your scale is always off by that amount.

Digital scales accurately weighed test loads whereas dial-type scale weights differed significantly (p < 0.05). Imprecision of dial scales was significantly greater than that of digital scales at all weights (p < 0.05). Accuracy and precision did not vary by scale age.

“Even though they may not be accurate, it may be good for tracking changes with a diet and exercise program,” says McCrory. “Just keep in mind that the scales might be off by 5%, plus or minus. Follow the instructions carefully. Taking a shower beforehand really makes the reading inaccurate!”

There is no industry standard for bathroom scales and brands do differ on the amount of error that they consider acceptable. So just because your scale is older, it doesn’t necessarily mean you need a new one. It’s probably still functioning just fine unless it was jumped on, dropped, or treated badly.

The Taylor Talking Bathroom Scale is sturdy, reasonably priced, and reads the weight aloud. The MyWeigh XL-550 is reliable, accurate, and is designed to measure and hold up to 550 pounds.

Low Battery or Unstable A/C Power Source – Low batteries are the most common cause for digital scale malfunctions. Your scale will seem sluggish or measure inaccurately when its battery is low. Faulty power adapters can cause fluctuating readings and inaccuracy as well.

When the scale says Lo/Low this means the batteries must be changed as there is low power that is not sufficient enough for it to operate properly. How to Change the Scale Batteries: Turn the Balance Smart Scale over. Remove the battery cover on the back.

Battery problems are often the cause behind digital scale display and function issues. Use a small, clean paintbrush or cotton swab to sweep the compartment free of dust or debris that might interfere with the battery connection. If that doesn’t solve the problem, try replacing the batteries with fresh ones.

If your scales are used multiple times throughout the day, every day of the week, normal wear and tear will occur faster than in scales that are used a few times per week. Therefore, if you use these scales more frequently, they should be calibrated more frequently — perhaps monthly.
