Mark,
Yes, I have the hole drilled as specified, .026 D (#71 drill I think), 4mm ED, 2.5" from sensor CL. as pictured. Upon initialization, I checked voltages as indicated in the second chart below.  I measured  the resistor on the board you provided, which is marked 3002 and measures 30.1k. I thought that was to be 4.99k. Could that be the problem?
Thanks,
Roger
