Strain gage full or half bridge and piezo-resistive sensors in 4-wire config-
uration 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 con-
tacts represented with dashed lines are on the bottom of the TEDS
module. Connect the + and - sense leads there.
When connecting cable lengths > 50 m, instead of the feedback
bridges you must solder in one resistor each with half the value of the
bridge resistance (1/2 R
