Chapter 4 Performance Verification Tests
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 1 on page 23)
• Low thermal test leads (such as Keysight 11053A, 11174A, or 11058A)
• Shielded test leads (such as Keysight 11000-60001)
Note To have your transfer standard 3458A Opt. 002 calibrated to 90 day
specifications, contact your Keysight Technologies sales and service office.
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.
Calibration Cycle The frequency of performance verification depends on the instrument's usage
and the environmental operating conditions. To maintain 24 hour or 90-day
specifications, the instrument should be checked at these intervals by a
metrology lab with test capability for these accuracies. For normal operation,
it is recommended you perform performance verification every year.
