CERTIFICATE OF CALIBRATION (original) (raw)
Instrument was allowed to stabilise for at least 12 hours before calibration. 4 Wire kelvin connections were used for ohms measurements below 10kOhms The instrument Serial interface was used during calibration Calibration Information The instrument was calibrated against laboratory standards whose values are traceable to recognised National Standards. The uncertainty limits quoted refer to the measured values only, with no account being taken of the instruments ability to maintain its calibration. The reported expanded uncertainty is based on a standard uncertainty multiplied by a coverage factor k=2, providing a level of confidence of approximately 95%. The uncertainty evaluation has been carried out in accordance with UKAS requirements. Calibrated By : EXAMPLE Date of Calibration : EXAMPLE This certificate is issued in accordance with the laboratory accreditation requirements of the United Kingdom Accreditation Service. It provides traceability of measurement to recognised national standards, and to the units of measurement realised at the National Physical Laboratory or other recognised national standards laboratories. This certificate may not be reproduced other than in full, except with the prior written approval of the issuing laboratory.
