How to Calibrate Prince Neos/Ektelon?

Is there a video anywhere on how to calibrate the Prince Neos/Ektleon type of stringing machines?

It's been a while since I've adjusted my machine. Not sure how do it it anymore.

There is a PDF file you could download with the instructions.

Basically, you need an allen wrench. There should be a small entance on the fron of yoru tenion head. You place the allen wrench in there and turn it (clock wise, or counter clock wise) depending on the tension reading you are getting.

Good luck!
Thanks. I have the manual but was hoping to see it done on video as well.

if you calibrate to get 50 pounds mark on the calibrator, is that 50 pounds lock-out reference tension, or tension ~5 seconds after lock-out (when the string has relaxed a bit already)

Since different strings have varying amount of stretch I actually use kevlar on my calibrator to at least try to reduce that variable as much as possible.

I have commented lock-outs on various occasions ;) I think it is a fast, easy to use method of tensioning, and many LO's have excellent stringing-tables and clamps. But the absolute accuracy is horrible. Most users of a LO will tell you: it doesn't matter that the absolute tension is not known. If you want a tighter stringbed, just put the reference-tension up, looser, then down. You could better have a scale from 0-100, and work from there ;)
Calibrating a LO is hardly possible ( in the absolute-value-meaning of calibrating). Same as with the actual stringing, the calibrating depends on type of string, speed of cranking. And, you would need an expensive measuring device that registrates the tension at lock-out. A simple spring-based-calibrator can not do that.
This means actually, that even two identical lock-outs will give different results if "calibrated" by different stringers. And again, this is not important if you only string for yourself.

I've seen some of your comments. I had a Gamma 6004 and there is not a drop weight or eCP that will come close to a drop weights accuracy. I have a peak hold meter and the instant the LO locks out the tension was exactly the same every single time.

That's for starters. I don't think you can get this for less then $200. All "calibrating" demo's are with a simple spring-calibrator.
And then you still have the influence of cranking speed.
But of course, if you tension and calibrate with same cranking-speed that's fine.

Don't know what you mean here; you mean "close to a lock-out accuracy" ?

No matter how fast you turn the crank the LO will always lock out at exactly the same tension.

I mean you will be not be able to hit the same tension on a drop weight two times in a row, on a 6004 LO it will lock out at the same tension every time. EDIT: Assuming you do not change the setting on the tensioner.

Irvin, you're right. Cranking speed has no influence on LO-tension. It has an influence on the "tension-of-the-tensioned-string-after-relaxation", but that's a different subject.

If you crank with incredible speed, the tension could be a bit higher though, caused by the split-second before the brake works, and the small distance the tension-head moves in that split-second ;)

I will bet you I can get the same tension on my SW-dropweight (with the same margin as in your favorite LO).
I am always surprised that people preach the blessings of a LO, but also tell you that changing to a Wise is the best step you can take ;)

I tried testing repeatability on a friends DW and he tried and tried to get the same tension and could never do it. The only blessing I was preaching was how accurate my 6004 was at lock out. I did use a Wise on it and not the crank. But the Wise would get you within the 1-2/10ths of a pound every time and that was close enough. For consistency of pull and speed the Wise has the advantage over a lock out tensioner. I also felt as though I could string faster with glide bars than I could with swivel clamps but swivel clamps are much easier to use and versatil.

I have two Stringway's. One is "first generation", with glide-bars. The other double-action swivel-clamps. I like the glide-bars best.
