How accurate is the Gamma Tension Calibrator?

[Litespeeds]

I have a Babolat Star 5 stringing machine and when I test the calibration with a Gamma Tension Calibrator, it is dead on. At 50lbs, the Star 5 pulls up to about 52-53lbs and drops back down to 50lbs. At 40lbs, it is perfect too.

I heard the Star 5 over shoots the tension but I feel 2-3 lbs is acceptable. The bottom line is it settles back down to the target tension.

The reason why I ask about how accurate is the Gamma calibrator is because feel my string jobs are much tighter than every one elses. I have a friend with a crank style Eagnas that tells me he strings his racquet at 56 lbs and I swear it would be around 42-44lbs on my stringer. I didn't have him use my Gamma calibrator on his stringer but is this normal?

You have a constant pull machine. It will be tighter than a crank at the same tension.

Absolutely true. The LO pulls to your set tension, then stops pulling. The string now starts to relax. The CP pulls to the set tension and will pull 'forever' at that tension until you clamp. Then the string will start to relax and lose tension. Normally this would be less because you have pulled more resilience out of the string with the CP.

Any sort of calibrator needs to be calibrated . Do we trust a five-dollar spring scale to 'calibrate' a $4000 machine? COMPARING tensions from machine to machine using the same calibrator can give us some info, but the Bureau of Standards ain't out there calibrating fish scales(unless they are commercial, in which case I reckon the USDA certifies them).

In other words...you have two 12" rulers that aren't exactly matching up. Which one is correct?

To put it another way, a man with two watches never knows the 'correct' time.

Dang...life is complicated !

^^^^ this. i have 3 scales for calibrating, haha. guess which ones read the same?

You need a calibrator to calibrate that calibrator? What's going to calibrate the calibrator that calibrated your first calibrator?

You can attach a 50 lb. weight onto your calibrator and see if it calibrates? But wait... are you SURE you have 50 lbs? You need to calibrate that!!!

1 cc of water equals a gram. So you need a 1k cc's to make a kilogram. But wait... you can't dangle water without a holder.........................................

I digress....

Just buy some weights.

The chance of them being off is sooo low.

You never heard of paintjobs, counterfeit or weights produced for the mass market?
