When I got my Wise 9 years ago (EDIT: turns out, it is exactly 9 years since this post), I did just as you suggest, and it was approx 4lbs tighter than my drop weight.On your first restring with the Wise, keep tension the same just so you can see for yourself.
Wow...I had no idea there would be that much of a diff btwn a crank/LO and an ECP in LO mode instead of constant pull mode. That's 25% of target tension, give or take a %.I'd go at least 10%. But, you can check yourself 1st by stringing one of your own rackets. Put the Wise on LO mode and set your reference tension to 48. It will pull, stop (in LO mode), and you can still see the tension that the string is pulling on the tension head. I'm betting it shows up at somewhere in the 35# range.
The Wise is not a true lockout. The tension on a Wise will drop faster than the tension on a lockout because there is no tension spring.As people have mentioned it is dependent on the string. Repeating what was said above you can do a pull with the Wise setup as Lock Out and see what the tension drops to after 3-5 seconds(or whatever time it usually takes you to clamp off). Then use that differential to actually string with that particular string as a starting point.
To minimize stretch too much, I would think either be super fast to clamp off after the handle locks out, or possibly pull tension twice may help…release first tension pull, then pull again and clamp as quick as you can. Seems those two things would be the only intervention a person could do.As I watch string stretch a little more if I wait a few seconds with a dropweight, I have often wondered how lockout machines deal with the tension loss from this 'final stretch'.
Apparently they don't??
If so, why would you want to ever use a lockout machine?
Edit:
This sounds rude. I don't mean that way. But is this just something that you have to navigate through when using a lockout machine?
And a little part I omitted in my previous post…could a person even be fast enough to make any difference at all, with his speed in clamping after lockout? I venture to say prob not when it comes down to it.Tension is just a number whether you use a LO or CP. In both cases, strings will continue to relax after clamping and 12 hours after finishing the racquet. It is also dependent on the stringer's movements. If the client likes 58# on a NEOS 1000 vs 53# using a NEOS 1000/WISE, then who cares since they are satisfied in both cases. There is nothing inherently wrong with a LO. What you want is to be consistent over a clients' multiple frames. An example is to do 3 identical frames using same string and ref tension at the same time. They should come off the machine at the same length and (for me) same tension as ref tension. After 12 hours, they should also be the same tension.

Once a lockout “locks”, how long you take to clamp doesn’t matter. I’ve had to bump up the reference tension compared to the shop I used to use to get the same tension on my poly strings. That’s about it.
Makes you question what tension people are referencing when they give advice. For poly, at least, would be good for people to indicate LO or not.
Good points, but if you double pull with a lock out it does matter. Double pulling with a LO will allow the string to stretch out more and although you will not have a higher than reference tension you will have so me thing closer to reference tension.Once a lockout “locks”, how long you take to clamp doesn’t matter.

Thats was my line of thinking, as in the machine stops pulling when it's still got quite a bit to go(relatively) before at least somewhat stabilizing, and when it stops relative to said stabilization varies alot based on the string being tensioned.
So with a constant pull (or dropweight for that matter) 50lbs is 50lbs, there's no '50lbs on this machine', with these string/machine model variables having to be estimated.
To be fair I am new to this, and what looks like a glaring flaw(outdated?) in design could be very much affected by my admittedly somewhat sophomoric opinion on this. There's definitely a lot I don't know, but it's hard to overlook this.
Grab the racquet tune app. Some will debate the accuracy, but for relative comparison, you will easily see a poly lose 5-10 lbs of tension overnight, even coming off a constant pull, because it’s poly. Have you ever seen anyone on a constant pull wait until the tension absolutely stopped changing? Me neither. All it does is keep it constant until you’ve clamped it and then it’s the same as a LO. The faster you string on a CP, the more it’s exactly like a LO.
Conversely, if after the lockout machine locks, you pull again (and again etc), the more it will be like a CP machine.Grab the racquet tune app. Some will debate the accuracy, but for relative comparison, you will easily see a poly lose 5-10 lbs of tension overnight, even coming off a constant pull, because it’s poly.
