BRIDGE COMPLETION RESISTORS
For single strain gage applications, bridge completion resistors must be employed externally to the module. Only use metal film
resistors with a low temperature coefficient of resistance.
Load cells and pressure transducers are normally implemented as full resistance bridges and do not require bridge completion resistors.
