9. Measure and record the DMM output as M1 in Table 8.
10. Set the Leveled Sinewave Output of the calibration generator to 450 Hz.
11. Measure and record the DMM output as M2 in Table 8.
12. Calculate the low frequency bandwidth ratio:
low frequency bandwidth ratio =
M2
M1
13. Record the results in the test record on page 20 and compare the results
against the low frequency specification on page 20.
14. Set the P6021 termination sensitivity to 10 mA/mV.
15. Set the Leveled Sinewave Output of the calibration generator to 50 kHz and
an amplitude of 5 V

.
16. Measure and record the DMM output as M3 in Table 8.
17. Set the Leveled Sinewave Output of the calibration generator to 120 Hz.
18. Measure and record the DMM output as M4 in Table 8.
19. Calculate the low frequency bandwidth ratio:
low frequency bandwidth ratio =
M4
M3
20. Record the results in the test record on page 20 and compare the results
against the low frequency specification on page 20.
NOTE. Dirty or worn mating surfaces between the transformer and the lid
degrade the low-frequency response. Clean them if necessary. See page 24 for
cleaning instructions.
