Pipette was cleaned and lubricated.

Inspections and measurements were performed in accordance with Allometrics work instruction 5-4WI06. Pass/Fail status determination is derived from allowable tolerances established in ISO 8655 unless other tolerances are specifically requested by the client. The uncertainty associated with these measurements is not included in the determination of Pass/Fail status. This calibration is traceable to the SI utilizing the equipment shown on the calibration certificate. This document cannot be reproduced except in full by the issuing lab.

Comments: Instrument was found out of tolerance. Instrument was successfully adjusted into tolerance. Inspections and measurements were performed in accordance with Allometrics work instruction 5-4WI06. Pass/Fail status determination is derived from allowable tolerances established in ISO 8655 unless other tolerances are specifically requested by the client. The uncertainty associated with these measurements is not included in the determination of Pass/Fail status. This calibration is traceable to the SI utilizing the equipment shown on the calibration certificate. This document cannot be reproduced except in full by the issuing lab.
