How curious, though I am unclear as to how this explains the 4.15mV / 3.9mV increment pattern.
Or are these values indicative of the inherent error span in the accuracy of a single point measurement? Presumably if we went for extracting raw data using the get_values routine, then we would have to calibrate the output because of this intruding data?
We have been considering upgrading to a 12 bit / 4096 step logger (the 4224). Does this reduction in bits available also occur with the newer devices and software? If so, do you know at what level of accuracy of the mV increment does it impact (for say the +/-500mV range)? Also if we did purchase a 12 bit logger, does the .PLW file have the same internal format structure for a 12 bit as for a notional 8 bit logger?
Sorry yet more questions.
