Why is calibration so important?

Why calibration is so important
Patient weight is a key piece of information that's used in many ways, including calculation of body composition, suitable medication dosage, evaluation of growth, and more.

Calibration of a professional scale to ensure accuracy and consistency is an important part of proper maintenance. A scale that is not properly maintained may result in less accurate results, which can have a negative effect on treatments that are dosed by weight, such as renal disease procedures.
 
I've purchased a high-end professional scale - does it also need to be recalibrated?
Hospitals and other locations where accuracy and reliability is paramount utilize professional medical scales. However, like any other precision measuring instrument, they are subject to wear and tear even in normal usage, which can, over time, cause deviation in accuracy compared to when the scale was factory fresh, if not regularly checked according to procedure and recalibrated if necessary. Calibration allows service providers to check if results have changed, and if so, correcting it before accuracy is affected.
 
When should I calibrate my scale?
Different countries may have their own regulations for how often a scale needs to be recalibrated, though typically, most facilities will have their scales recalibrated on an annual basis. That said, if a potential error has been noticed, then an earlier recalibration might need to be scheduled.
 
How does calibration work?
When conducting calibration, a certified professional will use a "known weight" (ex: 20 kg) and compare the scale's reading to this weight. If the difference exceeds a certain level, the scale is adjusted to it will correctly display the accurate result. It is very important to note that the known weight must be certified by an accredited test lab, proving that the weight is calibration-ready, traceable to master weights so you can ensure accuracy.
