Calibrating a personal scale

Time and again, a wide range of people ask themselves whether they can calibrate their bathroom scales. Whether this is necessary at all and how you must proceed when calibrating the personal scale, we have summarized below for you.

Determining whether the bathroom scale weighs correctly

Like any other scale, the weight is also determined with the personal scale. However, as you know for sure, there are big differences especially with personal scales. Therefore, from different households and work areas, the question arises again and again, where can a bathroom scale be calibrated?

Different adjustment options on the scale

However, the question should first be asked whether a balance calibration is necessary for the bathroom scale. For this it is first of all important to compare the different types of "adjustment":

  • the adjustment of a balance
  • the calibration of a balance
  • the calibration of a balance

the adjustment of the personal scale

The adjustment is with almost every body scale in the bathroom (or where you have set them up) possible. However, the adjustment does not take into account the measuring accuracy of the balance. Rather, the measuring range is adjusted. An example: You stand 5 meters next to the scale or you look directly from above on the scale of the scale. You will notice that the measuring point (arrow, line in the sight glass above the scale) does not lie directly above the zero marking, depending on the view.

But not only the perspective is crucial. Also, temperature (thermal expansion), altitude above sea level (NN), or frequent or less frequent use of the balance may cause it to be misaligned. Then you can use a thumbwheel to set either the glass, but usually the movable scale so that the zero line is directly above the measuring point. You will notice that the match already deviates, if they look very slightly from another angle on the scale.

Calibrating the personal scale

However, the adjustment just serves the correspondence between the displayed weight and the marked measuring point. The adjustment says nothing about the accuracy of the personal scale. If you do not trust your balance, or you want to make sure that the measurement is accurate before you buy, you can simply do a calibration. All you need is a counterweight with a fixed unit of measurement. Even better would be different weights, possibly even up to a weight between 20 and 50 kg.

This is how you can determine whether the balance is working exactly in all areas. For this purpose, the balance is first adjusted and then the weights are placed on the scale. Modern electronic scales can also be calibrated via a control button. Then the scale measures the weight and sets it to zero. Incidentally, calibration is also used elsewhere. For example, when calibrating copper pipes. E Calibrating the bathroom scales

Oak trees are nothing more than calibration, but now officially. Therefore, the calibration of a balance is done at a relatively high cost. The balance then gets a seal of approval, which is valid for a limited time.

There is no need to calibrate a standard bathroom scale that most people have at home. However, there are areas where a calibrated scale can be essential and also required by law. These include, in particular, medical personal scales in medical practices or hospitals.

If you want to calibrate such a balance, you can not do it yourself. Rather, you have to do this in the next calibration office. In addition, there are especially officially certified companies that have a calibration certificate, so may calibrate balances if necessary.

Tips & TricksIn our everyday life we ​​encounter a lot of institutions that have to be calibrated. For example, dispensers at petrol stations must be calibrated regularly, or even older tachographs (tachographs that record) in truck scales.
