Search for Powerbuilt digital torque adapter. It will help you determine the accuracy of the wrench, assuming you trust the Powerbuilt. Remember that the wrench's claimed accuracy of 4% or whatever is for roughly the middle of its range. If it is a 0-150 wrench and you use it at 10 lbs or 140 lbs, it may be 8% off. You would want to go down to a 1/4 or 3/8 or up to a 30-250 wrench for those extremes. Same goes for the Powerbuilt digital torque adapters -- they are also for specified ranges.
