Frequency
Gate Time...................................................................131 ms
Measurement Method .............................................AC-coupled input using the ac voltage measurement function.
Settling Considerations..........................................When measuring frequency after a dc offset voltage change, errors
may occur. For the most accurate measurement, wait up to 1 second to
allow input blocking RC time constant to settle.
Measurement Considerations ...............................To minimize measurement errors, shield inputs from external noise
when measuring low voltage, low frequency signals.
