LVDT to MCP3208

I have 6 LVDTs coupled to a MCP 3208 ADC. I want to take a voltage reading at the MCP3208. This does work but I'm questioning my results as they are lower that what I see on my scope 3.76 volts/ 2.72 volts. Also, there is a fair amount of sinusoidal fluctuation at the beginning of the signal. More troubling, sometimes I get a reading of 0 or 5 volts at the MCP3208. These values should always fall somewhere in the middle. I see that microchip has a filter design tool but I'm not sure what to enter for frequency parameters. (I have several seconds to make a reading).
Can someone nudge me in the right direction.
ps I'm using a basic stamp 2 as the uP.

I overlooked the conversion needed when dividing the voltage range by 4096. After applying the correct offset and multiplier I am getting the expected results.
