ADAS1000 amplitude overflow

Hello,
I have a problem to show you. If I make an ECG with Müller & Sebastiani MS-410 simulator, in CAL50000BL mode ([+/-5mV] ECG + [+/- 1mV] baseline noise) with ADAS1000SDZ rev B kit, I notice overflows in V1 to V6 channels.
I have not changed anything on the kit, and I've only initialized the kit with the "Default Settings" button.
This problem occurs in vector mode or electrode.
You can find the screenshots below.

RAW data (fig 6) show a zoomed part of V3, when the overflow occurs.
Unfortunately, the Frame Header, bit 27 (fault) remains at 0.
What is your explanation ?
Is there a solution to avoid this overflow ?
Is there a method to report this overflow ?


Sebastian.
