Wheels first huh?....Brave soul.....

Sorry but......You still need to use the knobs on the truing stand to check for side to side and up and down movement on the rim.

The tension meter will give you a number that corresponds with a given amount of tension in the book, Different rims like different tension settings (you can look them up)

For starters,just work on getting each side of the wheels spokes even and get the rim running true.....All at the same time!....

Tension will probably/should be even from side to side on the front wheel.....On the back,tension will be UNEVEN from side to side....This is normal! Just get the back wheels spokes even on each side.

That should keep you busy for a bit....
