I don't know that particular model. You have to have the correct fitting adapters for the specific torque wrench or screwdriver, and if there is a spanner handle extension, you have to use the correct one, as hanbdle length impacts accuracy.

Calibrating using a digital calibrator is quite straightforward. You have to have the calibrator rigidly mounted on a good work bench. Set each unit being cal'd to desired settings and slowly and evenly check it clockwise and counter-clockwise. Set the calibrator on peak hold and reset after each reading. Repeat each reading a number of times in each direction to assure repeatability. Some people like to use loaders which apply an even smooth pressure to the units until they click over.

That's the short answer. Let me know if I can help with any further level of detail on this.

Jerry,

I'd appreciate it if you would go into further detail. We use a fixture that utilizes a torque wrench to hold the part stable for further measurements and have noticed alot of variation related to the torque. Anywhere from 3-15% variation on a simple R&R.

Thanks,

ASD...

There's an ANSI standard B107.14M-1994 that may be helpful. You can get it from ANSI or you might try Global.
