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).
