# How do I calibrate my 150 point scale

## Calibrating the balance: what does it mean?

The calibration of scales is necessary so that you get a reliable weighing result. Since the measurement accuracy decreases with the use of the device, trolleys should be calibrated regularly. If you would like to calibrate your scale yourself, you will need a reference weight. If there is a large measurement error, you should have the balance adjusted.

### That is why it is important to calibrate a scale on a regular basis

The accuracy of a scale decreases over time due to regular use. External factors such as shocks can also influence their reliability. In order to get reliable measurement results again, you should calibrate your balance regularly. How often your scale needs to be calibrated depends on how often it is used.

### What happens when a scale is calibrated?

When calibrating a scale, regardless of whether it is a kitchen or bathroom scale, its measurement accuracy is checked. To do this, it is necessary to use a reference weight in order to determine whether there is a measurement error.
1. To calibrate your scale yourself, you have to place a test or reference weight with a known mass on your scale.
2. Document the displayed value and calculate the deviation from the true value. This so-called measurement error results from the difference between the measured value, i.e. the value read from the balance, and the real value of the reference weight.
3. In the event that there is a measurement error and you want to rectify it, you can have the balance adjusted by a specialist. The balance is realigned during adjustment.
