Hello guys, I was wondering if it was normal that my wise2086 jumps from time to time (about 5-10% of the time). It can sometimes over pull (no pre-stretch) and then releases and then pull back again. I set my tension at 11,5kg and it jumps to 11,8-12,2kg, releases to 11,8kg and pulls again to 12kg. The process is not smooth and can be quite jumpy and most of the time, the tension is higher than what I set What I'm doing when it happens is just to stop and pull again. What do you think that may cause that and what should I check?
The tension was set at 12kg. As you can see, at the end, it can pull up to 13kg . Constant pull was on, speed on the lowest and no pre-stretch
I just tested mine and it is pretty stable. constant pull was on and once in a while it will stutter and little but the tension don't fluctuate more that 0.3lbs (less than 0.2kg) and always settle down to something within 0.2lbs of the target tension. so a 1kg fluctuation might indicate an issue.
From what I can see, no slipping from neither. I will try with an old racket that I can abuse of it to double check. Beside, something crosses my mind. Do you think the power outlet could cause any inconsistency ?
Here I only pulled the first main string. You can notice the sound coming from the wise pulling. Don't know if mine is faulty?
I suggest you to put the highest and see if the issue is still occurring. Sent from my CLT-L29 using Tapatalk
Not 100% sure if it's about the same problem but maybe you can check the following forum. There is also someone who has a problem with his Wise (just be aware that the thread is in German but maybe you can use Google etc. to translate it): https://www.saitenforum.de/board/showthread.php?t=31620&page=6 Which version of the Wise do you have? Because on page 3 it says: "We have noticed that Version 14 Wise units are much more sensitive than Version 12 and before." Personally I have version 12 and don't have any problems with it (like over pulling etc.). Hope this helps
That behaviour would not have been normal on my WISE; mine would never go more than 0.3 lb (0.1 kg) over the set tension. And it would never make that clacking sound .
Thanks, I will have a look at it. I have contacted tennishead and they suggest me to calibrate the wise. We will see if the problem still remain. I have the v14.
If the string is fresh, then after it has reached initial tension and the string keep stretching, the WISE will pull a bit more in order to maintain the target tension. However, I am not sure if that's what happening here. The complete illegible tension readout doesn't help.
As far as I know, this is a bug of the firmware. Contact Wise. In the German saitenforum forum is a thread about it: https://www.saitenforum.de/board/showthread.php?t=31620
Yes, the wise will keep pulling to cope with the stretch of the string but not to that extend. I've downloaded the firmware from that forum. I'll proceed to the update today
I just did a stringjob after the firmware update. It seems to be much better. It occasionally stutter but it's much less pronounce as before. I also notice that the reading of the tension was less sensitive than before as it doesn't seem to react to the string stretching and re-pulling. It makes me wonder if the firmware update has done something to cover/hide the problem. One stringjob is probably not enough to confirm anything. I will keep you posted after several stringjob ^^
Question here, may I know if firmware if v12 need to be upgraded as well? Sent from my CLT-L29 using Tapatalk
All I can say is if it works well, you don't really need it. In my case, I had to because of that behaviour. Else I wouldn't have upgraded the software
