we are using our ADC-20 for some measurements, and we have some questions regarding the conversion time and resolution of the logger
1) The conversion time is per channel so if it's set at 60ms , there will be 16 measurements for 1 channel, 8 for 2 channels etc. This also means that for conversion time set at 660ms for two channels , the time interval should be greater than 2x660ms. Right?
Now.. what happens if it's a differential channel and not a single ended one? How many measurements are taken for the differential channel? For example... in 60ms.. will there be 16, or 8 measurements per second on one differential channel?
2) What is the resolution of the logger in V and not in bits. For a conversion time of 340ms or 660 ( 20 bits)
the actual resolution I seem to get is not the one I calculate by the bits either on the scale of 1250mv or 2500.
Does the documented resolution in the manual refer to single ended channels thus it's different with differentials?
Thanks in advance
