Siglent SHS806

I recently purchased a Siglent SHS806 oscilliscope.

I m trying to record the captured waveform and extracting data via usb.

However, the data value extracted via USB is does not tally with what was shown on the oscilloscope.

I m reading a data from the power supply, measuring 0v-15v.

The oscilloscope is reading 0v -15v correctly.

I plotted the graph via the CSV file

But the data recorded to the usb is not in Voltage, 0v-15v (see attached picture Y-Axis), but in some random values (i assuming is in either bits/byte, but unable to determine the conversion).

I did see other user getting the data that corresponding to the oscilloscope reading (e.g showing 0v-15v on the data), but it did not post a way/guide to setup the reading on the axis.

My oscilloscope firmware is 5.09.01.05

Is there some settings that i need to adjust, so that whatever the oscilloscope detected corresponds to the data recorded values, especially on the Y-axis value, as I have been struggling for a few days already.?

Look at the file header

CH1
Time/Point:1ms
Volt Coef.:200000uv
Zero Pos:128

The conversion looks simple from that-
V= (value - Zero Pos)* Volt Coeff

Using the formula, I calculated that value 129 corresponds to 0.2V, 128= 0V and 203=15V

Looks plausible to me

The axis data look more valid right now.

Also, are we able to set in the oscilloscope so that it directly shows the value instead of having this data and manually calculate to the final data?

Thank you

Probably no. I don't have the 806, so I just looked through the manual, I don't see any options.
Of course, manuals usually are bullshit and only give some clues at best.

But it's not that difficult to recalculate, if you already have the data in EXCEL. You only have to write one simple formula and paste it all the way.
