Has anyone tested for calibration by hanging weight on it, or better yet at a testing facility?

I haven't but I no longer use it, after I stripped a pedal screw with it. In my opinion the tool is not accurate and the scale is not precise enough if are going to work on carbon frame. The are better torque ranches for not much more on amazon.

I can only speak for the one I received as the short directions didn't mention specific requirements for calibrating.It was only after I first attempted to calibrate that I became aware of this. I pushed the buttons according to the directions. A few seconds after it started a self-check, the screen flashed '1000.0g', which of course I didn't have. I did have a total of 1000.0g in a set of inexpensive calibration weights but I couldn't add them to the scale fast enough and the calibration was off accordingly.I did purchase on Amazon a single inexpensive non-certified 1000.0g calibration weight for $16.00 and it worked perfectly.I hope this helps you out.

No it doesn't come with a weight for calibration. I use a US coin to help me calibrate. You really don't need one for this scale.

I have purchased two of these and both were in perfect calibration out of the box. One is still new but the other one has been working well and has held calibration for 10 months. If you do want to have calibration capability all you need is a 500 gram weight. a nickle weighs 5.1 on both of mine and a dollar weighs 1 gram even.

I have always taken to lowest value. Most persons that calibrate say not to leave at any set point. Then again if you want precision the lab where I worked at required calibration every year with cal certification papers. Bottom left is your answer. http://www.snaponindustrialbrands.com/dsn/wwwsnaponindustrialbrandscom/Content/PDF/CDI%20Click%20Wrench,%20Plastic%20Handle%20Operation%20Manual.pdf At lowest value which would be 30 ft/lb

The only way to answer this question definitively is testing to failure, and I doubt anybody has done that, including the manufacturer. They are cheap enough, so if that is critical, why not order a pack and hang some weight from them?

not with any kind of accuracy. it's not weighted for that as-is. You might be able to modify it for that purpose but i wouldn't recommend it.

I had the same issue. I purchased the weights to properly calibrate but still nothing. In my honest opinion, this scale is trash. Sorry

I do not use a calibration weight since I am using my scale for espresso. I am just interested in repeatability, not the exact weight. The others made great suggestions on using coins.

As I recall the calibrates when you tap the platform with your foot and let it settle. You need to do this whenever the unit is moved.

We have been using the scale 4 months, we have not calibrated it. We used it right out of the box, just make sure to use, on a level flat surface.

best way to check for accuracy is a good grade surface plate and you cant adjust them but you can calibrate it it comes with instructions how to calibrate it

There is no "calibration" procedure for this unit (at lease not one listed in the manual). I suppose one might measure a known quantity of distilled water at a specific temperature and see how accurately the unit measures that calculated weight.

the calibration packet I ordered never made it here so I was unable to calibrate it unfortunately and that is likely the problem....I thought that they may be also calibrated from the factory so I did not worry when my calibration packet didn't come but I guess they must not calibrate at the manufacturing place?

It appears to be accurate and to hold the zero. As with any scale, be gentle placing the loaded tray back on the scale.

It comes with maybe a ketchup packet worth of calibration solution which will calibrate initially. You can go about a month without calibrating. It falls off a point or 2 by then.

Mine came with a 100 Gram weight to calibrate... I let something a bit heavier sit on it the other day and say a number in the 300's and it blanked. On the box there are 2 "check boxes", a 100 Gram Capacity and a 200 Gram Capacity. My check box is the 100 gram version. Again though, I have mistakenly seen over 300 on mine (causing blank), I just don't know that it was accurate as I wasn't trying to get a measurement.
