APPENDIX A
NOTE
The Performance Specifications listed below for the TI are absolute specifications which are
calculated by combining the uncertainty of the relative specifications found in the commercial data
(operators/instruction manual) with the uncertainty of the Calibration Standards listed in Section 2,
Equipment Requirements of 33K series calibration technical order (TO) . This is accomplished by
calculating the Root Sum Squared (RSS) values using the individual formulas identified in Table 1.
As opposed to Relative specifications which do not include calibration standards uncertainties and
other possible uncertainties, Absolute specifications are the traceable measurement capabilities (or
calibrated to specifications) of the TI . The Absolute specifications contained in this appendix are
supplied for technical reference and have been subject to rounding . These specifications have not
been used to calculate the limits used in the calibration procedure ; for the calculation of any specific
limits value, the technician must apply the formulas and specifications for the individual ranges being
used from Table 1 .
NOTE
All notes in the commercial specifications, with the exception of the OEM Factory traceability notes,
still apply . OEM notes containing information (such as specification adders) that have already been
applied to the absolute specifications have been noted below and do not need to be applied. In order
to achieve the most accurate measurement be aware of the necessary settings and temperature
degradations.
This instrument is calibrated to the absolute specifications listed below:
