For all those new torque wrench owners out there here is another Utah lesson:
When you have finished torquing, and prior to putting the wrench away, back off the handle to "zero" or less. You want to take all tension off the spring. If you do not do this the spring will take what is known as a compression set and future reading will be in error. Great it is calibrated when you bought it but leave compression on the spring for a month and all bets are off!

P.S. If you have one read the owners manual! Pretty clear in there.

Look at the TQ series and go down to where it says characteristics and tell me what you see.

You know guys Utah is one of the few here...the very few to admit he made a mistake. In this case my bad. I reread the thread and reviewed some data not previously available to me....thank you...you know who you are 
. It appears the device in question uses a strain gage and not a spring mechanism to baeline the torque value. As such the unit does not need to be zeroed. My bad! Sorry for any confusion I introduced here. The unit in question is digital electronic and somehow I missed that. My comments still apply to those with a dial gage.......
Sorry again,
