Calibrating Alpha Ghost 2

Anyone know how to Calibrate the Alpha Ghost 2 tensioner? I emailed alpha for a digital copy of the owners manual but did not get any response. Also looked briefly online and no luck. Only found a spec sheet for the alpha ghost. Thank you in advance

I think it's like the Head TE -3300 - you don't have to calibrate anything, the machine does that by itself every time it starts.

I have the book with the instructions for adjusting the setting if you need it please message me. I have looked at it on mine. You have to take the display plate off and there is a potenitiometer you have to adjust.

Thank for the reply. I will message you lobalot. I checked the tension on a manual prince calibrator and it said the machine is 2-3 lbs low.

Did you see this in Constant Pull mode? Or in lockout mode?

Note sure it matters as much in CP mode, but i'd use a string that doesn't stretch much, Kevlar or thick/dead poly (especially if checking calibration in LO mode). I'd even it double it so there's even half as much stretch again. 2-3 pounds isn't alot and those spring calibrators aren't uber accurate and are even
hard to read "accurately". Plus, if one of them (I have one too) was to read wrong, I'd expect it to be low just by design rather than read too high.

Your machine is likely spot on/or dayuum close, especially if there is a self calibration.....even the WISE has that (self diagnostic or whatever, maybe i'm out of line here?)

it was in constant pull mode. I agree with your points, manual Spring calibrators are hard to read unless dead on 5lbs increments. I do use Kevlar to calibrate (ashway braided). I also want to calibrate my calibrator but not sure there is anyway to adjust the reading.

agreed that 2-3 lbs is not the end of the world but it just got me thinking that I should know how to calibrate in the future. Also I need to get my hands on a manual. I was watching videos on calibrating other machines on YouTube (Thanks herb) and was hoping it was going to be as easy. Gamma ELS and Wilson Baiardo process is well designed

You can see if your calibration device is accurate or not. Look up how much a gallon of water weighs. It is 8.34#. Weight your empty bucket on a food scale. They are accurate enough. Then start pouring 1, 2, 3, 4 gallons of water into the bucket. Lift with scale and compare reading. When done, water the plants or lawn with the "Keep Off My Lawn" sign. 8-B:happydevil:

Or you could do water in 5# increments using your food scale and bucket. In both cases, you will be able to determine if your scale is good or not.

The calibration procedure on the Tourna 700-ES is easy. Turn on machine, run through each calibration point (6 of them) one at a time, adjust each reading to match gauge, and save results. Except for gauge no tools needed and nothing to take apart.

thank you Esgee for the suggestion. I was going to use a combination of weighted work out plates and a luggage to test out the calibrator. The water idea is brilliant though. Easier to fine tune the weight.

It’s doesn’t look too hard for the alpha thanks to instructions posted by lobalot. With the AG2 I am still undecided about the features of the interface. Part of me likes the simplicity of the menu. It is boiled down to the essential functions and nothing else. Although I think it could do without “string type feature”. Then again it’s nice to have functions like a programmed calibration function. I have an in-depth review of the AG2 written up and will post soon.

anyone know if the newer babolat machines are easy to cailbrate? I don’t ever remember calibrating the star 5 I used in a shop setting. Star 3 calibration is similar to the alpha where it is a manual adjustment but it rarely went out of spec.

Thank you! Sorry I didn't do the whole book. It has been a bit busy lately between, work, my son's tournaments, and helping him prep for his first year of college in the fall.

If you don't hear back from where you bought it let me know and will try to find the time to get the rest of it done.

That's great, EXCEPT FOR THE FACT THAT ABSOLUTELY NOBODY asked about a tourna 700 in this post/thread..... Zero, Zilch, Nada.

Maybe you should also present the procedure for the Star 5 while you're at it....

In a YouTube video someone said that the pull on the Alpha Ghost 2 fluctuates a lot. He set it at 55 pounds, and his scale showed the tension ranging from 52 to 57 when being constant pulled. He compared it to the Baiardo (both original and lite) where when he set it at 55 pounds, the pull stayed within a tenth of a pound of 55 pounds.

Anyone have a similar experience with the Ghost 2?

The video is here (see the 24:00 mark):

I have not had that issue at all.

Nope. I had recently ran a tensioner test in my machine and everything was fine.

You can calibrate a machine’s tension yourself, but no present machine is going to do it for you.

On the older Alpha Ghost 2, like mine there is a speed pull adjustment (presets for kevlar, regular and poly string). Basically, that determines how quickly it pulls and I can imagine some variance if its pulling at full speed but in low/medium I doubt there would be any variance like described in that video.

I just strung a racquet and attached the tension gauge while it was pulling to see if I could replicate what he is describing. In "high" speed mode, I can maybe see a couple of pounds of difference very briefly....maybe, but it's not clear. I'm pulling 52lbs for reference.
