ZERA DAkkS calibration laboratory
Since the year 2000, ZERA has been operating its own calibration laboratory (D-K-15103-01-00) accredited by DAkkS. Through regular auditing, traceable standards as well as clearly defined surrounding conditions, the DAkkS accreditation guarantees a high quality of calibration according to DIN EN/ ISO IEC 17025:2018.
The accreditation allows us to calibrate the following quantities for measuring electricity:
- Direct current and low frequency
- Direct voltage
- Alternating voltage
- Alternating current
- Electrical power
- Electric energy
- Phase angle
- Voltage ratio
- Current ratio
About the procedure
Our measuring devices receive an adjustment with predefined ZERA standard load points before calibration.
Subsequently, we calibrate your device in our accredited DAkkS laboratory with ZERA standard load points.
This calibration and the stated measurement uncertainties in the calibration certificate ensure direct traceability of the measurement results to the PTB (Physikalische Technische Bundesanstalt).
An overview of the load points can be found in the sample calibration certificates of the corresponding devices on our service pages.
