How To Use Weighing Scales?

We all need to weigh something from time to time. Like myself. Or a bucket of potatoes. Or a portion of ice cream. Modern household electronic scales allow you to do this with unprecedented accuracy. If only to be able to use them correctly.

Many factors influence the weights. Unfortunately, they cannot be completely excluded. But you can minimize their impact why you need to know what affects the work of weights and how to fight these phenomena.


How to use Weighing Scales? Analog, Digital and Smart scales

The list includes a huge number of items, but we will list the most important.

First of all, it is the accuracy of the calibration. Most of the scales are calibrated at the plant, but they still need to be checked before the operation starts. Moreover, the verification procedure must be carried out before each weigh-in.

The weights can be affected by drafts or dust settled on the parts of the device. It not only adds weight but also worsens the friction of moving parts.

Sensitive scales will change their performance depending on the temperature. This is especially true for electronic models, so they necessarily use a thermocompensation scheme. The readings are also affected by the moisture condensation that has settled on the details.

The device will show distorted data if there is a powerful magnet nearby. Distortions are particularly great in models with magnetic sensors.

Indications will also be confused by the power of Coriolis, which arises as a result of the rotation of our planet. Therefore, a kilogram, weighted in St. Petersburg, may not be a kilogram in Nalchik.

For desktop and floor structures, the structure and angle of the surface on which they are installed are important. A soft carpet or a crooked table will also affect the performance of the device.

Another factor is seismic disturbances. And it is not necessary that the active volcano thunders nearby. It is enough to pass a truck or a subway train so that the scales show the wrong result, which should.


Ways to fight

First of all, you need to take care of the regular calibration of the device. You can find a set of weights with the exact weight on sale, which you need to store along with the scales. And before each responsible weigh-in, check the device with a control mass. Many modern electronic models allow you to calibrate them with such kettlebells independently.

If the scales are just brought from the street to the room, it is necessary to give the device time to heat it. This will save not only from temperature distortions but also from problems with condensation.

It is necessary to protect the device from dust and dirt, to keep away from the technique with a powerful electromagnetic field.

When weighing the machine, the scales should be put on a flat and hard surface. It is necessary to protect the device from vibrations and blows. If it is a nod, the device should be stationary at the time of weighing. It is advisable to hang it on a reliable stationary hook; weighing with the hand will be less accurate.

Putting the load on the platform of scales, it is necessary to try to place it in the site’s centre. The cargo should be stationary; it should not touch anything other than the platform.

It is worth remembering that over time the device’s mechanical parts wear out, there are backlashes and unpredictable friction forces. Thus, the accuracy of the device will fall over the years, and nothing can be done about it. If high accuracy is needed, the scales will have to be changed periodically to new ones.

However, it should not be forgotten that high accuracy is meaningless in some cases. For example, to weigh a person is enough accuracy in half a kilogram, as an adult man or woman’s weight can fluctuate within a couple of kilograms during the day.
