# Signal/Preamp Issues # 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. - If the signal is too high (saturated) or too low, the preamp gain can be adjusted with the trimpot on the preamp PCB.

- 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. - Similarly, the PD gain can be adjusted with the trim pot on the side of the PD (look for the hole in the case).

# Serial Connection Issues
- The following error indicates a hangup at the serial port or that the serial device did not shut down correctly:
```julia
ERROR: libserialport returned SP_ERR_FAIL - Host OS reported a failure.
```
Usually trying to run the program again is sufficient to clear the error. If the error does not clear itself after 3 or 4 tries, reset the serial device by unplugging the USB cable and plugging it back in.
