Measurement range & accuracy

QardioBase has a measurement range of 9 – 396 Lbs (5-180 Kg).


QardioBase measures your weight to an accuracy of 0.2 Lbs (100g) with 4 sensors. Our proprietary fine tuning processes ensure the highest accuracy of measurements.


To get the most out of your QardioBase, try these tips to improve accuracy:

  • Thanks to its design, QardioBase works well on most surfaces. However, some people tend to move more when the scale is positioned on certain soft surfaces and movement can effect accuracy. If you encounter problems while measuring on a soft surface, you should move the scale to hard surface and repeat the measurement.

  • If you do not have a hard surface available, do not use the extra feet provided to ensure accuracy. 
  • Ensure that you are completely dry. 

  • Try to measure your weight each day on the same scale at the same time to see consistent trends. Avoid measuring after intake of alcohol, caffeine or other stimulants, after intense sport activity, after heavy meals, or in case of dehydration problems.

  • Ensure accurate data are included in your profile (height, age, biological sex) in the Qardio App.

  • If you have picked up or moved your QardioBase between measurements, it may perform a calibration. In case of calibration, Step on, or tap QardioBase with your foot to activate it. Once the scale turns on, step off.  Wait until you see a smile displayed, and then step back on the scale again to perform your measurement.
