data acquisition electronicsinformation used in DASY system to align probe sensor X to the robotcoordinate system.

Methods Applied and lnterpretation oI Parameters. DC Voltage Measurement: Calibtalion Factor assessed for use in DASY system by

comparison with a calibrated instrument traceable to national standards. The figure givencorresponds to the full scale range of the voltmeter in the respective range.

. Connector angle: The angle of the connector is assessed measuring the anglemechanically by a tool inserted. Uncertainty is not required.

. The following parameters as documented in the Appendix contain technical information asresult from the performance test and require no uncertainty.

. DC Voltage Measurement Llnearity: Verification of the Linearity at +10% and -10./. ofthe nominal calibration voltage. lnfluence of offset voltage is included in thismeasurement.

. Common mode senslllylty. lnfluence of a positive or negative common mode voltage onthe diff erential measurement.

. Channel separallon. lnfluence of a voltage on the neighbor channels not subject to an

input voltage.

. AD Convefter Values with inputs shorted Values on the internal AD convertercorresponding to zero input voltage

. tnput Offset Measurement Output voltage and statistical results over a large number ofzero voltage measurements.

. lnput Oltset Cunent. Typical value for information; Maximum channel input offsetcurrent, not considering the input resistance.

. lnput resistance; Typical value for inlormation: DAE input resistance at the connector,

during internal auto-zeroing and during measurement.

. Low Battery Alarm Voltage:fypical value for information. Below this voltage, a battery

alarm signal is generated.

. Power consumption. Typical value for information. Supply currents in various operatingmodes.
