Does it need to be calibrated regularly, as other torque wrenches do?

All torque wrenches made should be calibrated over a period of time/use and more often if accurate torque is absolutely necessary.

Motor torque seems higher in this tool than in other tools. RPM doesn't indicate torque.

I occasionally check it against my "glass torque wrench", one that I keep calibrated and only use to test. I found this to be absolutely accurate and consistent. I did what you wrote, bought a 1/2 and use a 3/8 adapter when necessary. Of course use a quality, short adapter to maintain accuracy.

Yes, I just bought one and although I can adjust the torque to maximum, it requires a good deal of effort and takes what I think it too long to set especially since it is recommended that it be brought back to zero after use. I am planning on returning mine.

Hi Jefte, this wrench calibrates the torque you use to tighten nuts and bolts. Your expression "calibrating engines" I cannot understand. Ed

No. I suggest checking the torque after you tighten each bolt, nut, etc. My applicaton is automotive only however if torque is not as critical perhaps in some constructions situtations, this is a great tool.

No does not require calibration. I compared with another scale and it was accurate.

Yes, there are N-m markings on this wrench. However, the markings on the rotating handle (the black part) are only in ft-lbs so you have to estimate a bit when setting to N-m value (can't dial in an exact figure). It does also include a conversion chart to convert from N-m to ft-lbs which may be preferred if you want to set the wrench more precisely. Hope this helps.

I have had mixed results with mine. Some times it will remove the lugnuts and some times I need to break them free and then I'll move over to the impact wrench to spin them off. If you are expecting it to remove them every time I would not bet on it. (I don't use to it to put on lugnuts, I tighten to spec with a torque wrench.)

To Jan S. Balcom's answer, I would add that I believe this calibration needs to be done every time you put in a new battery. You also need to recalibrate the compass each time. By doing this, I believe mine gives a reasonably close reading.

You can't just set a torque value on this wrench; you have to put it into a memory location. Memory is maintained across power cycles.

The only answer to your question that I have is that I didn't have to calibrate mine, and it seems to work correctly. This is not a hi-tech compass. It's pretty cheap overall. But if you can't afford a good one, it works in a pinch. It sticks to your window wherever it is convenient for you.

Well, one thing for sure, it provides you the actual torque value you have reached. You might not like what you seen in the readout but it is what it is. It is still hard for me to accept the fact standard torque wrench can actually over-torqued the nut. Maybe it is because the sudden jerking movement did it.

Yes, it works best for angle readings when you can move the wrench the full amount without having to ratchet, but any angle can be set

Yes. The wrench is reversible so it will measure the torque for left handed threads.

It's for calibrating the tool. They say the calibration needs to be checked ever so often and possibly adjusted if needed.. I haven't used it though..

No. It't not a torque wrench. It's an "Impact" wrench. It simply applies whatever torque is required (all the way up to it's maximum) to break fasteners loose or fasten them down. If you want to apply fasteners to a specific torque, you need a "torque" wrench.
