relays that switch the resistors in and out of the input circuit to provide
shunt calibration and quarter-bridge completion.
The quarter-bridge completion resistor has a factory default value of 350
Ω
for use with a 350
Ω
strain gauge. These resistors are placed in sockets on
the terminal block so you can easily replace them with resistors suitable to
your specific strain gauge. If your application requires a 120
Ω
strain
gauge, use the eight 120
Ω
resistors included in the kit.
For a complete description of the use and operation of the SCXI-1520
module, refer to the
