Capacity Readability (d) 8 g g 0 g g Calibration Guideline: METTLER TOLEDO Work Instruction: 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.

4 gl acc 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 9%. The user is responsible for maintaining environmental conditions and the settings of the weighing instrument when it was calibrated. Measurement Uncertainty of the Weighing Instrument in Use Stated is the expanded uncertainty in use with k =. The formula shall be used for the estimation of the uncertainty under consideration of the errors of indication. The value R represents the net load indication in the unit of measure of the device. Temperature coefficient for the evaluation of the measurement uncertainty in use: Temperature range on site for the evaluation of the measurement uncertainty in use:.0 0 ⁶ / K K Linearization of Uncertainty Equation Range 0 g - 8 g U₁ = 0.00 mg mg/g R U₁ = mg mg/g R 8 g - 0 g U₂ = 0. mg mg/g (R - 8 g) U₂ = 0. mg mg/g (R - 8 g) Examples for Various Net Indications Net Indication g 0.00 mg 0.% mg 0.6% g 0.00 mg 0.0% mg 0.06% g 0.0 mg 0.000% mg 0.00%.0000 g 0.0 mg 0.00% 0.07 mg % g. mg % 0.9 mg 0.000% Software Version:..0.0 Page of
