# Signal/Preamp Issues
- If the signal is too high (saturated) or too low, the preamp gain can be adjusted with the trimpot on the preamp PCB. Clockwise increases the gain, counter-clockwise decreases the gain. ***Note that adjusting the gain will necessitate a new calibration, so avoid adjusting if possible!* The DAQ card has a maximum signal of +/- 1V.

- Similarly, the PD gain can be adjusted with the trim pot on the side of the PD (look for the hole in the case). Again, this is typically rolled into the calibration and should not be adjusted unless absolutely necessary.
