How to set tension on my pans?

Hi gang,
I am attempting to set the tension on the pans, after realizing the yotes are feeling way too much relief in them.
Can you tell me what you use to set the two pounds of tension?
Thanks,
Chris

IF YOU THINK THEY ARE FELLING THE PAN TRY TO SET THE TRIGGER AS LIGHT AS YOU CAN GO BEFORE ITS TRIPPED. WATCH YOUR FINGERS!!IF YOUR USING A BAITED SITE OR CUBBY, FOUL THOSE YODIES IN PUTTING A TRAP ON THE TRAIL WHERE THEY WILL HAVE TO STEP SOMEWHERE BEFORE YOUR ACTUAL SITE.

2 lbs. is light for coyote try 3 -4. The coyote is more likely to avoid a light pan then a heavier tension. You increase or decrease tension by tightening the nut and bolt that hold the pan. Use a weight for measuring tension.
