1) Slide in 30 deg stroke (written on back) and 40 deg stroke (written on back) and 3^rd galvo into mounting block. Push galvos all the way into mount.

2) Attach first mirror to galvo. Remove the shafts the galvos come on for shipping. Push mirror all the way along shaft.

3) Couple a test laser beam into the pentaprism, level and parallel to whole pattern on table horizontally. Use target card with target in position of pentaprism. Adjust position of whole apparatus such that the back reflection goes along the same vertical plane.

4) Hook up Y1 first, on power up make sure no faults - LED turns green. Note that X cable /  Y cables have different endings. Make sure to put mirrors on before turning galvos on.

5) Set Y 1 output voltage to 1.5V - which is approximately 6 V on the input.

6) Rotate angle of Y 1 mirror such that the reflected beam is coming of at an 8° angle.

7) Did fine adjustment of voltage offset to hit 8°, see voltage is 1.511 V

8) Mount the other Y 2 mirror, adjust position so beam perpendicular coming out -4.8mV

9) adjust X angle so comes out level, 0.6 mV
