8. Press the 3458A Multimeter's
voltage calibrator is used, skip this step.
9. Set the RC Box resistor to 10
10. Set the DC power supply (voltage calibrator) to 1 V.
11. Press
to start measurement.
12. Record the multimeter reading (voltage calibrator setting) on the calculation sheet on the
Multimeter Reading line.
13. Record the 4349B reading on the calculation sheet on the 4349B Reading line.
14. Set the DC power supply (voltage calibrator) to 0 V.
15. Calculate the test result according to the calculation sheet, and record the result into the
performance test record.
16. Perform this test for all settings listed in Table 9-3. The DC power supply (voltage
calibrator) must be set to 0 V after each test. The measurement time is changed by using
. The measurement time setting is indicated by the Meas Time annunciator(
