ZS9001 | Recalibration service

Beckhoff has offered analog input devices with a factory calibration certificate or external calibration certificate (ISO17025 or DAkkS). These are EtherCAT Terminals with a unique ID number (BIC/BTN), which are not only compensated/adjusted to the device specification in production at Beckhoff like all other input devices, but are also delivered with a calibration certificate. This represents a clear added value, because the certificate specifically names the remaining deviation at the specified test points. Using these values, it is possible, for example, to increase the achievable accuracy in the individual application. The device can also be traced via the unique ID. Generally speaking, a calibration always represents a review; it confirms the suitability of the device examined according to the specification for the foregoing usage period.

Like the first certificate, the newly issued calibration certificate can be downloaded as a PDF from the Beckhoff website, quoting the ID number. Beckhoff recommends a recalibration interval of one year; of course, it is necessary to comply with the operating conditions according to the specification of the device.

Applied to I/O products with Beckhoff factory calibration certificate

The Beckhoff recalibration service allows analog input devices that have already been in use to be tested, readjusted if necessary, and recalibrated. The method used for this is the same proven method that is used in production. The devices must be returned to Beckhoff Service, quoting the recalibration order data.

For each set of identical terminals that are to be recalibrated, a ZS9001 order processing fee must be included in the order. The recalibration procedure is only possible for products that have already been delivered ex factory, e.g., as a -0020 version, with a factory calibration certificate. In particular, it is only possible for devices with an ID number or BIC/BTN.

Example:

• Terminals to be recalibrated:
  • 5 x EL3602-0020
  • 3 x EL3751-0020
• Resulting order:
  • 2 x ZS9001
  • 5 x ZS9001-EL3602-0020
  • 3 x ZS9001-EL3751-0020

The Beckhoff recalibration service is available for the devices listed below. Further products in preparation or on request to measurement@beckhoff.com.

Application to I/O products with ISO17025/DAkKS certificate by calibration service provider

In principle, all initially calibrated I/O products can also be recalibrated. Please contact your local distributor or measurement@beckhoff.com with your request.
