Hi Guys wondering if anyone can help me out with the power output on my tested chronograph hw100kt.
Test readings
511.6
518.2
520.5
531.3
542.1
535.9
Don't know if it's FPS I'm still coming to terms with the chronograph reader never used one plus no instructions but thanks to a guy on here for putting up the instructions I just realised is on my thread thank you fellow Shooter.
 
yes they would be the speed in fps (feet per second).
Guessing its a . 22 cal gun?
you just need to put those fps figures coupled with the weight in grains of the pellet into a ftlb calculator to manually give you your ftlb power reading if your chrono doesn't do it for you.

use the link @Tricky-Dicky posted above to calculate your ftlb power 👍

What pellets were they? Could be under 10 ft lbs or higher with heavy pellets.
 
Sniper@123, dont worry I just started to Chrono my gun as well and it is a learning curve, but as you can see above the reading from your chrono is only part of the info, to get the FT/lb you need to do a sum knowing what the pellet weight is as well.

That spread is a little on the wild side for a HW100. Was it at the start of the fill or mid fill? The jump from 520 to 531 and then from 531 to 542 is worring. That's a spread of 22fps over three shots. Is the barrel clean? Did you weigh the pellets?
 
I posted a PDF on your other thread that might help.
Do take into account all the suggestions above.
If you aren't sure enough of the weight of the pellet tested, figures may well vary because of the weight spread of individual pellets. 🤷🏻‍♂️
Use the average weight, or the one printed on the tin, but your measurement will only be as good as the info you enter.
