tension question (stringmeter)

[ionutzakis]

I've measured with a Stringmeter the tensions on all my racquets. All of them are in the range of 40-50 (relative tension), except one.

It's a racquet strung with Babolat Pro Hurricane 16, which I strung at 59/56. But when I measured the tension with Stringmeter, it shows 60 on almost every place on the racuet.

Why is that? Is it because it's a poly and the string do not move? The string does not feel as tight, I played one month with it.

thanks

Stringmeter readings for different types of string material will vary. What, for instance, is in those other racquets? This is how it's a good idea to have more than one way to measure tension -- such as this one: http://www.eagnas.com/maxgen1/etest.html -- until you have a history for the string type to go by.

the other racquets are all strung with synthetic (Sensation and Stamina) or natural gut (Klip legend). Only one rasquet is strung with poly

 

[Valjean]

Poly is stiffer; so is kevlar. This is how the manufacturers of those strings can recommend they be strung 10-15% lower than a typical solid-core synthetic, when switching over.

Those two will often give higher readings, therefore. You can still track tension loss, and when you achieve the tension you want, use that value to manage consistency from one string job to the next.

I haven't heard of a stringmeter... So it measures the tension after you have strun the racket up? How does it work? Is it electric or is it a pulling type thing? Does it crimp the strings?

stringmeter isn't that great.. money is better spent on an ERT 300 which test the entire stringbed stiffness.. something the stringmeter can't

A Stringmeter is $30, wheras an ERT 300 is $200.....

The Stringmeter isn't perfect, but you can get a "feel" for tension over the stringbed by testing several areas about the center....

 

[dufferok]

Stringmeter is great for getting a measurement after you have strung and using that measurement as a guage for future tension loss. Stringmeter does NOT give you the exact tension...it should only be used as a reference tool. If you want exact tension you can use a cool little program written by another forum member. You will also need a microphone or a way to record sound using your PC. Here's the link:

ERT 300 can not measure tension of individual string of a string bed.
Stringmeter is only device that can estimate it.

No problem. That would be your reference number for futuring stringing
of that particular string.

Stringmeter measures stiffness of strung string. Estimation of the tension is
actually your job, so to speak.

Most nylons measured similar. Natual gut obviously yield lower number
and poly/kevlar shows higher number..

Measure at the same relative spot on each frame.

Recognize that string/frame contact points and cross string/main string contact points produce friction and that friction varies by the string outer wraps. More friction--lower tension reading.
