shows a typical single-channel wiring diagram for a Half-bridge
Strain Gauge connected to the STP-AI-208 panel. As the figure indicates, you
should remove the board-mounted jumper when you use a 4-wire circuit. Note
that a half-bridge circuit requires that you solder precision resistors to the board
where indicated in
to complete the measuring bridge. As an alterna-
tive, you can install precision Resistor-Divider Networks in SOT23 packages
directly on the board to complete the bridge circuits.
