Methods Applied and Interpretation of Parameters * DC Voltage Measurement: Calibration Factor assessed for use in DASY system by comparison with a callbrated instrument traceable to national standards. The figure given corresponds to the full scale range of the voltmeter in the respective range. * Connector angle: The angle of the connector is assessed measuring the angle mechanically by a toolinserted. Uncertainty is not required. * The following parameters as documented in the Appendix contain technical information as a result from the performance test and require no uncertainty. * DC Voltage Measurement Linearity: Verification of the Linearity at +10%and —10%of the nominal calibration voltage. Influence of offset voltageis included in this measurement, + Common made sensitivity: Influence of a positive or negative common mode voltage on the differential measurement. * Channel separation: Intluence of a voltage on the neighbor channels not subject to an input voltage. * AD Converter Values with inputs shorted: Values on the internal AD converter corresponding to zero input voltage * Input Offset Measurement Output voltage and statistical results over a large number of zero voltage measurements. * Input Offset Current: Typical value for information; Maximum channel input offset cutrent, not considering the input resistance. * Input resistance: Typical value for information: DAE input resistance at the connector, during intemal auto—zeroing and during measurement. * Low Battery Alarm Voltage: Typical value for information. Below this voltage, a battery alarm signalis generated. + Power consumption: Typical value for information. Supply currents in various operating modes. Contficate No: DAE#—877_Maria Page2o5
