Optional AC Performance Verification Tests
These tests are not intended to be performed with every calibration.
They are provided as an aid for verifying additional instrument
specifications. There are no adjustments for these tests; they are
provided for performance verification only.
Configuration: AC VOLTS
LF 3 HZ:SLOW (in the Advanced menu)
1
Make sure you have read “Test Considerations” on page 71.
2
Select Channel 210, select the AC Volts function and the 3 HZ filter.
Before executing each test, you must press
to enable reading
monitoring on the selected channel (or use the
ROUTe:MON
command
from the remote interface).
3
Select each range in the order shown below. Compare measurement
results to the appropriate test limits shown in the table. (Be certain to
allow for appropriate source settling.)
