Robert,
do you own a schematic of the diode sensors? The schematic for the thermocouple sensors was hard enough to obtain. In the current service manuals, there are of course no schematics at all, and the HP journals of that time also don't show the actual schematics
of the sensors.

Interesting project. The diagram you show is for the Thermocouple "A" suffix sensor. While the principle and basic circuit is the same for diode and thermocouple, the A2 PCB is different so there must be a difference in the circuit. This may be related
to your offset issue.
