Remember it is a yaw RATE gyro which means voltage changes from 2.5 V nominal proportional to how fast the turn is as opposed to how far it turns.

This means that in order to test the signal by yourself you have to spin the sensor and read it at the same time. When it operates properly,if you spin it in one direction (your choice), the voltage either climb to nearly 4.375 volts or fall to nearly 0.625 volts. When you spin the gyro in the opposite direction (your choice), the voltage climb/fall will be opposite before. This is a very simple test to make sure your sensor is operational. When stationary, the gryo will read about 2. 5 (+/- 0.1 volts).
Hope this helps.
