Strain gage full or half bridge and piezo-resistive sensors in 4-wire configuration with
Zero-Wire TEDS, version for D-sub-HD15
Important: The solder terminals on this TEDS module are not labeled. On the
side with the four contact surfaces (in the diagram above) you must connect
the adjacent contacts (short circuit or feedback bridges), otherwise the
measured value is always invalid. The contacts represented with dashed
lines are on the bottom of the TEDS module. Connect the + and - sense leads
there.
