Ketone Reading factor corrected #6

Closed pascalfribi closed 5 years ago

pascalfribi commented 5 years ago

Hi,

long time not talked.

I have been in contact with a user who informed me that the Ketone readouts were wrong. Analysing the problem I found out that the factor is not ceil(value/2)/10 but value/18. Funny enough this is the conversion factor to convert glucose values from mg/dL to mmol/L. I do not think that the molecular mass for ketone is the same as for blood glucose, but it seems that the engineers just used this factor (apart from the fact that ketone is reported in mmol/L everywhere in the world). At least the tests with my user and the comparison to the results of the libre app have shown that with this conversion the values are correct.

I have corrected the description for this, so that others can also correct this.

Hope you are doing fine anyway :-)

Thank you!

Yup all good here, although getting the sensors for the Libre in the UK is turning out to be a bit of a mess :(

I have a couple of reverse engineering projects open right now, but haven't made enough progress to update the repository in a while, hopefully before Summer there will be a couple more protocols :)
