Details
The sample rate determines how fast the Model DMM7510 acquires a digitized reading.
Set the sample rate before setting the aperture. If the aperture setting is too high for the selected
sample rate, it is automatically adjusted to the highest aperture that can be used with the sample rate.
Example
dmm.digitize.func = dmm.FUNC_DIGITIZE_CURRENT
dmm.digitize.aperture = 0
dmm.digitize.samplerate = 1000000
dmm.digitize.count = 1
print(dmm.digitize.read())
Set the digitize function to measure current.
Set the sample rate to 1,000,000, with a
count of 1, and automatic aperture.
Make a digitize measurement.
