Half Bridge Circuit
When using the SGA with a half bridge load cell, two additional resistors must be placed in the circuit. The resistors should be rated to the same value as the
maximum resistance of the load cell’s internal resistors and must be placed as shown in the diagram above.
Quarter Bridge Circuit
When using the SGA in conjunction with a quarter-bridge load cell, three additional resistors must be placed in the circuit. These resistors should be rated to
the same value as the maximum resistance of the load cell’s internal resistors and must be placed according to the diagram above.
