calibration

We organize the calibration of your scale(s) - here in the factory or at the customer's premises.

• appointment with the calibration office
• Preparation of calibration application and other documents required for calibration
• provision of calibration weights
• If necessary, prior repair and/or adjustment of the scale

calibration of vehicle scales

You can tell when your scale needs to be calibrated again by the calibration mark that was applied during the last calibration. If the scale was purchased calibrated and has not yet been calibrated by the calibration office, you can tell by the information on the type plate.

Calibration mark:

The year indicated in the square with inward-curved edges indicates the year in which the calibration period begins.

Optional additional sign (information mark)

Marking of conformity-assessed scales (scales initially verified by the manufacturer)

The year after the M indicates when the scale was put into circulation. This is also when the calibration period begins.

Calibration periods for commercial scales (Class III)

type of measuring device	calibration period in years
Industrial scales (maximum load less than 3 t)	2
Industrial scales (maximum load 3 t or more)	3
vehicle scales (maximum load 3 t or more)	3
counter scales	2
personal scales in hospitals	4
Personal scales, unless installed in hospitals	permanent
livestock scales	4

Here are some examples:

A counter scale with this calibration mark would have to be calibrated again in 2018.

A vehicle scale with this marking on the type plate of the evaluation device would have to be recalibrated in 2019.

According to § 38 of the Measurement and Calibration Act, the required recalibration should be requested from the relevant calibration office at least 10 weeks before the end of the calibration period (i.e. the year in question). This has a big advantage! If you submit the calibration application on time by then, your measuring device will be considered a calibrated measuring device until the official inspection and it can continue to be used until then. So if you only get an appointment for calibration in the following year, your scale will be considered calibrated until then, even if the calibration period has actually expired.

Please contact us if you have any questions or if you would like us to organize the calibration for you.
