- | This trimpot sets the gain for the AUXILIARY SERVO OUTPUT. The Aux Servo is a pure integrator and the gain ranges from 500 μs to 5 s. It is a 20-turn pot. Full ccw sets gain to minimum (5 s), full cw sets gain to maximum (500 µs). | + | This trimpot sets the gain for the AUXILIARY SERVO OUTPUT.

If you are having problems locking the laser, it is a good idea to not use the AUXILIARY SERVO OUTPUT as this complicates the system. Once you get the locking to work properly, you can reconnect this cable. | If you are having problems locking the laser, it is a good idea to not use the AUXILIARY SERVO OUTPUT as this complicates the system.
