| - Manually locate the four corners by adjusting the position of the sensor using the software. Increasing the position in the positive x-direction shifts the plate towards the right side of the box, and increasing the position in the positive y-direction shifts the plate towards the back of the box. Once at the corner of an active region, the observed waveform amplitude will decrease and totally disappear. | - Manually locate the four corners by adjusting the position of the sensor using the software.

| - Once the four corners have been located, shine the laser somewhere in the middle of one of the four quadrants. There is a macro script to run which adjusts the z position (height) of the laser while measuring the voltage. Using this, we can find out the optimum distance the laser should be from the sensor. | - Once the four corners have been located, shine the laser somewhere in the middle of one of the four quadrants.
