ACCURACYDETAILED ACCURACY SPECIFICATION GUIDECONDITIONSThe following conditions must be met for the unit to meet its accuracy specifications1) Warm up time: > 30 minutes2) Temperature: 23 ± 5 °C3) Fixture: Built in4) Open & Short Circuit Calibration have been performed5) D < 0.1 for Capacitance MeasurementsQ < 0.1 for Resistance MeasurementsQ > 10 for Inductance MeasurementsACCURACY EQUATIONSThe accuracy of a measurement is a function of the basic accuracy at that frequency, measurement rate, thesignal amplitude, and where the impedance of the DUT is within the measurement range. The basic accuracycan be determined from the impedance graph or from the individual parametric graphs. Additional factors aredetermined by the measurement conditions and the impedance of the DUT. From these, the accuracy of ameasurement in its optimal range can be calculated. See the following section for effects due tomeasurements made out of an optimal range.3-1
