I set tensioner on 20 lbs and measure with fish scale. i use 20 cm scrap string (BG66) to connecting the fish scale. The Fish scale reading 20,5 lbs right after the tensioner stopped then decrease and steady on 19,4 lbs. For 20 lbs : Do i have to calibrate the machine 20 lbs right after the tensioner stop? Or 20 lbs after it steady ( apprx. 6 sec. after the tensioner stop)? Thanks for any advices...
Actualy the fish scale on "hold" position after 6 second, thats the last reading. I already calibrate after 6 six second, but when i strung 25 lbs feels like 28 lbs before the crank was calibrated, thats why i doubt it, is it a correct way to calibrating... Thanks Pete for share
However long it takes you to clamp the string after pulling is how long you should wait before calibrating; once you clamp, the crank head isn't providing tension any more. For me, this is a four-count.
For cranks, the tension versus time graph bottom out about sixty seconds after lockout. This is when set your crank.
Did you read the manuel? From the ones that I've read it says to calibrate it at a much higher tension at like 50.
Yes, that's correct! There is an upper range and lower range. 50 lbs is the upper range for calibration.
They cant be linear when i try to calibrate every + 3 lbs, on 20 lbs was good but not on 26, 28, 30, there always different 0.5 to 1 lbs margin. I see the crank will not giving us the best calibrating linear-graph like digital machine. Maybe i have to take 25 lbs as my point of calibrating since 25 lbs very common to all my friend.
I thought most of Indonesia played at range 28 - 32 lbs ? even beginner they strung at 28 - 29 lbs ? ... hehez
Not in my town bro, we usualy use 24-26 lbs, with a good calibrated crank machine, i think 26 lbs is enough, hehehez..
Take the reading as soon as the tension lever pops. As soon as a crank machine reaches tension the string starts to relax and the tension drops a good explanation including graphs can be found here http://www.stringforum.net/board/showthread.php?t=3829
