Capacity Readability (d) 8 g g 0 g g Calibration Guideline: METTLER TOLEDO Work Instruction: EURAMET cg-8 v..0 Sample ACC ISO70 WI v..0 This calibration certificate contains measurements for and calibrations. The sensitivity/span of the weighing instrument was adjusted before calibration with an internal weight. In accordance with EURAMET cg-8, the test loads were selected to reflect the specific use of the weighing device or to accommodate specific calibration conditions. Temperature Environmental Pressure conditions have been verified to ensure Pressure the accuracy of the Start:.7 C End:. C calibration. Start:. C End:. C This certificate is issued in accordance with the conditions of accreditation granted by ALA, which is based on ISO/IEC 70. ALA has assessed the measurement capability of the laboratory and its traceability to recognized national standards.

4 ACC-USL-S The uncertainty stated is the expanded uncertainty at calibration obtained by multiplying the standard combined uncertainty by the coverage factor k which can be larger than according to EURAMET cg-8. The value of the measurand lies within the assigned range of values with a probability of approximately 9%. The user is responsible for maintaining environmental conditions and the settings of the weighing instrument when it was calibrated. Test Equipment All weights used for metrological testing are traceable to national or international standards. The weights were calibrated and certified by an accredited calibration laboratory. Weight Set : OIML E Weight Set No.: 0 Date of Issue: 8-Jul-06 Certificate Number: MT006 Calibration Due Date: -Jul-07 Remarks The user should re-verify the performance of the equipment on site with appropriate standards prior to use.
