GGV2 samples at 2mhz due to overlapping ADC sampling. Dma moves readings to a ring buffer. You can get more than 44khz sampling with sound card. I get 96khz...

The acrylic case is probably blocking most of the beta from the source, if you check it with the case open, I think you'll find that the beta will peg your 700...

OK, tried that with the 700. On the x100 range with the source touching the probe window grille, it eventually stabilizes at 7.5 mr/hr closed and 9 mr/hr open....

Did you check both sides of the disc with the 700? One side has thicker epoxy than the other and blocks more of the beta. These are what I get with Cs-137...
