I do tend to check my machine on three setting 24Ibs, 45Ibs and 62Ibs
they are just setting I use.
As you can see below I was using 52.8Ibs, so not bad for a cheap way of checking your machine tension, (allowing for the slight stretch of the strap) the machine looks good.
Now all I have to do is check/clean the clamps on both the tennis and badminton clamps (and the tension head clamp ) and we are good for another 20 or so rackets.
Note: The Wise 2086 does it's own tension test as part of it's power on test at start up! By hey I like to be sure!
