shows a typical single-channel wiring diagram for a Quarter-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 3-wire Circuit. Note
that a quarter-bridge circuit requires that you solder precision resistors to the
board where indicated in
to complete the measuring bridge. As an
alternative, you can install precision resistor-divider networks in SOT23 pack-
ages directly on the board, as shown in
, to complete the bridge cir-
cuits.
