Basic information
Nothing is changed on the measuring device during calibration. Calibration means that the displayed values are compared with a reference standard. If the displayed values fall within the measuring device’s tolerance of the standard, no adjustment is usually made.
If deviations exceed the tolerance, or at the customer’s request, an adjustment (Calibration) to the standard value can be carried out (depending on the device). Recalibration is required following an adjustment.
The customer must define the calibration interval according to their requirements (e.g. 1 year). As a calibration laboratory, APTOMET is not permitted to prescribe a calibration interval for customer equipment (in accordance with ISO/IEC/EN 17025). However, we would be happy to advise you personally on defining calibration intervals → Contact.
An SCS calibration is a calibration within an accredited scope. The accredited measurement procedures have been reviewed and approved by the accreditation authorities. The accredited scopes are listed in the SCS directory.
In the case of ISO calibrations, the measurement procedures are not verified by an authority. However, we apply the same processes as for the accredited procedures.
Verification and calibration are often confused. There is an article by the SAS (Swiss Accreditation Service) that explains the differences simply and clearly. Publication courtesy of the SAS: Often confused activities.
Calibrations
Yes, for devices with batteries or a rechargeable battery, we check the condition of the batteries and, if necessary, replace them.
Yes. For mains-powered devices, we carry out a safety test in accordance with SN EN 50678 / SN EN 50699 as standard.
We will inform you immediately of the deviation. Upon consultation, the deviations may be accepted (the instrument meets your requirements), or the instrument may be re-adjusted or may need to be repaired.
Order
We have listed the key details for you and have also produced a separate document on Chauvin Arnoux test leads: Information Sheet C A Test Leads
The name APTOMET is derived from the words ‘apto’ = to fit precisely (Latin) and ‘metrology’ = the science and technology of measurement (not to be confused with meteorology!).
Certificates
Yes. Please specify your requirements when placing the order or let us know so that we can note the certificate format in your contact details.
Yes, we document all calibrations in a certificate containing the measured values. The customer can provide evidence of the calibration during an audit using the issued certificate.
