Voltage error at timebase slower than 100ms/div

Using PicoScope 6.6.23.2 with 2205MSO:

Channel A monitoring a fixed 5.1V signal shows correct voltage on both scope and measurement when the timebase is selected at 100ms/div or faster.

At timebase of 200ms/div or slower both the scope and the measurement show 5.77 volts with the same 5.1V input signal.

Hi I have recreated your problem, this appears to happen when in block mode, I have reported it as a bug.

The beta version of the software does not have this problem.
