I've viewed all, and downloaded most, info at the link that you've mentioned. Unfortunately, the data I'm looking for isn't there. In the E Series Calibration Procedure document, there is an extensive listing of tables that contain calibration data points for a variety of E series boards. However, the 6052E board isn't listed. Elsewhere on the ni website, there is a note to use the 6034E/6035E tables for the 6052E boards. These tables do not contain all the gain settings for the 6052E. I would assume that the 6052E boards were factory calibrated at all possible gain combinations.
