Bridge Balancing and Verification

Make sure then NI DAQ box is turned on before starting the VI. Adjust the measurement

time to 0.01 second on the LabVIEW program to view instant strain readings. Use the offset

potentiometer to adjust the output voltage to 2.5V, which is half of the output range.

Connect shunt resistors parallel to the active gauge, and observe appropriate change in

the strain reading.

Gently press on the tap of the can, and observe the strain readings change accordingly.

Take Measurements

Allow the amplifier to warm up for 5 minutes before taking measurements.

For each beam, continuously pluck the end of the cantilever for 30 seconds and record the

vibration decay curves.
