As this is an oddball metrological discipline, I won't get my hopes up....
But does anyone have any adjustment diagram info for a Millipore (Tylan) CDLD-11S12 or any CDLD series baratron? I spent about a whole day trying to reverse engineer the span, low linearity and high linearity on one of these. I finally managed to get it in spec across its full operating range; but only after plotting numerically how much each adjustment attempt impacted which parts of the range.
