CMCs represent expanded uncertainties expressed at approximately the 95 % level of confidence, usually using a coverage factor of k = 2. The actual measurement uncertainty of a specific calibration performed by the laboratory may be greater than the CMC due to the behavior of the customer’s device and to influences from the circumstances of the specific calibration. 3 Agilent 3458A with Option 2, settings DCV, 100PLC, ACAL within prior 24 Hrs, 1 year cal cycle. 4 Transfer using Agilent 3458A. 5 Agilent 3458A four wire ohms, ACAL within prior 24 Hrs, NPLC 100 < 100E6 Ohm > NPLC 10 6 Calibration Factor 100 kHz to 10 MHz is effective efficiency only. 7 Measure and Generate is limited to below 5 kHz; Measure only above 5 kHz. 8 The stated measured values are determined usi ng the indicated instrument (see Comments). This capability is suitable for the calibration of the devices intended to measure or generate the measured value in the ranges indicated. CMC’s are expressed as either a specific value that covers the full range or as a percentage or fraction of the reading plus a fixed floor specification. 9 The statement of CMC does not include the effects of mismatch error. 10 Add (12 μV/V) * (Vinput / 1000)2 for voltage > 100 V unless used as a characterized transfer. 11 In the statement of CMC, the value is defined as the percentage of reading unless otherwise noted, and R is the resolution contribution from the unit under test. 12 Points identified in the Parameter/Range reflect the reference standard range for which the CMC applies. 13 The 5790A/3 may be used to characterize the 5720A/3 and 5725A to generate CMC values. 14 The type of instrument or material being calibra ted is defined by the parameter. This indicates the laboratory is capable of calibrating instruments that measure or generate the values in the ranges indicated for the listed measurement parameter.
