Diode Verification Test
Configuration: Diode
1 Connect the calibrator to the front panel Hi and Lo input terminals.
2 Select each function and range in the order shown in Table 4- 6. Provide the
input shown in Table 4- 6.
3 Make a measurement and observe the result. Compare measurement results
to the appropriate test limits shown in Table 4- 6. (Be certain to allow for
appropriate source settling when using the Fluke 5520A.)
Frequency Verification Test
Configuration: Frequency
1 Select the frequency function.
2 Select each range in the order shown in Table 4- 7. Provide the input voltage
and frequency indicated. Compare measurement results to the appropriate
test limits shown in Table 4- 7. (Be certain to allow for appropriate source
settling.)
