We recently realized that we were using the wrong coefficients for our CS106 Barometric Pressure Sensor. We were using those for CS105 and not the 106.
Specifically,
What we were using (CS105 code incorrectly used for a CS106 sensor): VoltSe(BP_inHg,1,mV2500,1,1,0,_60Hz,0.184,600.0)
What we should have been using (CS106 code): VoltSe(BP_inHg,1,mV2500,1,1,0,_60Hz,0.240,500.0)
We have fixed this problem for future measurements but I would like to correct the historic record.
Is there a simple equation I can use to convert the historic data to the correct measurements?
Thank you,

Just use a speadsheet to backout the old mult and offset to get the original raw values and then apply the correct mult and offset.
correct_value = (((old_value-600)/0.184)*0.240)+500
Thank you! That's exactly what we needed.
