Webb,
The link didn't specify how...so based on my experience with Zodiac boat compass boards:
1. Align the axis of the aircraft on a compass rose in the north direction.
2. Utilizing a non-magnetic tool, adjust the compass until it reads 360*/000*.
3. Align the aircraft on the compass rose in the south direction.
4. With the non-magnetic tool remove one-half the error.
5. Align the aircraft along all the cardinal and sub-cardinal headings and note the deviations to compile your compass deviation card.
I hope this helps.
Note that the aircraft should be running and all normally used electrical equipment that might have an effect on the compass should be on.
