Methods Applied and Interpretation of Parameters: e DC Voltage Measurement: Calibration Factor assessed for use in DASY system by comparison with a calibrated instrument traceable to national standards. The figure given corresponds to the full scale range of the voltmeter in the respective range. e Connector angle: The angle of the connector is assessed measuring the angle mechanically by a tool inserted. Uncertainty is not required. e The report provide only calibration results for DAE, it does not contain other performance test results. Certificate No: Z18—60213 Page 2 of 3
