strange data acquisition

Recommended Posts

I have a PXI setup with a PXIe-4081 DMM in it.
I am trying to capture a current waveform, at 25kHz.
For some reason the first 8 seconds of the data capture seem to float, after which the signal stabilizes.

Does anyone know the cause, and solution for this problem?

below is a snapshot of the data.

The DMM is connected in series with a LED load, which is connected to a DUT.
