Description
Programmable to 1 s, 100 ms, and 10 ms
Flexible counting technique. AC-coupled input using
the AC voltage measurement function
When measuring frequency or period after a DC
offset voltage change, errors may occur. For the
most accurate measurement, wait up to 1 second for
the input blocking capacitor to settle
To minimize measurement errors, shield inputs
from external noise when measuring low-voltage,
low-frequency signals
