Copy and use Table D-26, Performance Test Record, to record performance verification test results for the Agilent E1441A. This table shows Agilent E1441A instrument accuracy, Agilent 34401A/E1412A Multimeter measurement uncertainty, and test accuracy ratio (TAR) values.

Test limits are defined using the specifications in Appendix A of this manual.

For the performance verification tests in this manual, the measurement uncertainties are based on the 90-day accuracy specifications for the Agilent 34401A Multimeter and the Agilent E1412A VXI Multimeter.

Test Accuracy Ratio (TAR) for the Agilent E1441A is defined as Agilent E1441A Accuracy divided by Measurement Uncertainty, where accuracy = maximum allowable value - expected reading. That is:

MaximumValue – ExpectedReading

TAR = ----------------------------------------------------------------------------------------------
