4 Performance Verification Tests
54 Keysight 3458A Calibration Manual
Introduction
This chapter contains performance tests designed to verify that the 3458A
multimeter is operating within the specifications listed in Appendix A. The
Performance Tests are performed without access to the interior of the instrument.
Required equipment
The equipment required for the performance tests is listed below. Equipment
other than that recommended can be used as long as the specifications of the
substituted equipment is equivalent to that recommended.
– Fluke 5700A AC/DC Standard
– Keysight 3325A Function Generator/Frequency Synthesizer
– Transfer standard DMM (3458A Opt. 002 within 90 days of CAL)
– Low thermal short (see Figure 3-1 on page 39)
– Low thermal test leads (such as Keysight 11053A, 11174A, or 11058A)
– Shielded test leads (such as Keysight 11000-60001)
Test card
Results of the performance tests may be tabulated on the appropriate Test Card
located at the end of the test procedures. Make copies of the Test Cards for
performance test tabulations and retain the originals to copy for use in future
performance testing. The Test Cards list all of the tested functions and the
acceptable limits for the test results.
To have your transfer standard 3458A Opt. 002 calibrated to 90 day
specifications, contact your Keysight Technologies sales and service office.
