What are folks using for torque wrenches for 25~30 in-lbs?
I have an old MiT/Tekton/Avery 20~200 in-lb wrench from 20 years ago. Did some testing and calibrating (calibrated at 95 in-lbs, verified at 47.5 in-lbs), and found out it reads 5~10 in-lbs off at the lower range (3lb weight at 9.5 in, should click at 28.5 but clicks until the 35 or so setting is dialed in). Some web surfing reveals that most wrenches are accurate from 20% to 100% of full scale, meaning a wrench with a maximum reading of 125 in-lbs would be needed to accurately measure 25 in-lbs.
It's certainly possible I did not store the wrench at the lowest setting, but would that account for poor low end accuracy after recalibrating in the mid range?
I suppose I could set the wrench to click at 30 in-lbs and press on, regardless of what value it's supposed to be set for, but I would like something that I can reliably set and use.
Thanks!
