Request calibration of measuring instruments
Service Description
Measuring instruments used to determine measured quantities in commercial or official transactions must provide correct results, i.e. they must be calibrated. In this context, "correct" means that a device operates within certain permissible error limits (traffic error limits).
Devices and equipment in the trade are regularly calibrated so that the customer receives exactly the quantity that he pays for. For example, speed and exhaust gas measuring devices, taximeters, energy and water meters are also calibrated.
Calibration marks on the measuring device - usually labels (adhesive marks) and/or seals - prove that the measuring device may be used in legal metrology within the calibration period.
Process flow
First check on the meter when the last calibration was performed. For brand new meters, the two-digit number next to the CE marking indicates the year when it was placed on the market. In most cases, the calibration period is two years. Exceptions are regulated in Annex 7 of the Measuring and Calibration Ordinance (MessEV).
Calibration is only carried out on application. The user is responsible for submitting the application at regular intervals.
If you have any questions about calibration, the staff of the responsible offices will be pleased to help.
Who should I contact?
Please contact the responsible regional department of the Thuringian State Office for Consumer Protection (TLV).
Gas, water, electricity and heat meters in supply networks are calibrated by state-approved testing laboratories.
Requirements
Measuring instruments are calibrated if they are used for the purposes specified in Section 1 (2) and (3) MessEV and are used to determine at least one of the measurands specified in Section 1 (1) MessEV.
Which documents are required?
The following information about the measuring instrument must be available during calibration:
- Nominal operating conditions
- mechanical and electromagnetic environmental conditions
- upper and lower temperature limits
- humidity conditions
- suitability for open or closed location
- instructions for installation, maintenance, repairs and tests
- instructions for ensuring fault-free operation
- information on special operating conditions
- Conditions for compatibility with interfaces, subdevices or measuring instruments
What are the fees?
Fees are charged in accordance with the Ordinance on Fees for Measurement and Verification (Mess- und Eichgebührenverordnung - MessEGebV).
Additional fees may apply if the application is submitted late.
What deadlines do I have to pay attention to?
Calibration must be applied for ten weeks before the calibration period expires. If the application was submitted in time, the measuring instrument is deemed equivalent to a calibrated measuring instrument after expiry of the calibration period until the time of the official inspection.
If the user has applied for calibration at a later date and it is not possible for the authority to calibrate the measuring instrument before the calibration period expires, the authority may allow the measuring instrument to continue to be used until the date of the official inspection. According to MessEGebV, this decision is subject to a fee of 25.20 EUR.
Processing duration
The processing time depends on the time schedule and can be requested from the responsible offices.
