AC Current
The following A
C current specifications are for sinusoidal signals with amplitudes
greater than 5% of range. For inputs from 1% to 5% of range, add an additional
error of 0.1% of range.

Characteristic Description
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 extern al noise when measuring low-voltage,
low-frequency signals
