You don't...you just double check it. This product is junk. Do not waste funds on it.

The scale is automatically calibrated to zero when the scale is turned on as long as it is on a flat level surface with nothing on the scale. If you are weighing items over and over again and somehow with nothing on it, it does not show zero, then you can hit the "tare" button and it will re-zero itself out.

With nothing on the scale, it should read "0.00" or just "0" If it isn't then with nothing on the scale touch the button that says "Tare." That will set it to "0." If that doesn't work then you may have a troubled scale. If you do have a troubled scale, it is an exception and not the rule. these are very good scales. You can do this if you place an empty container on the scale. The scale will show you how much that empty container weighs. Touch the Tare button and it will go to all 0s. Then you can add whatever it is you wish to weigh. Now if you remove the product and the container the scale will now show a negative number. Just hit "Tare" and it will go to 0s again.

It seems to calibrate itself upon startup. It will calibrate itself to zero if you turn it on with a container that you intend to fill already on it. As for it's need to be calibrated for accuracy, we'll we just have to trust to the gods of electronics. That said, I've never felt it might be even slightly beyond negligible where error is concerned. I'll buy another if mine ever poops out!

Calibration is not possible to the best of my knowledge. I have found it to be accurate + or - 1 or 2 grams and I think that is more a sensitivity issue (placement, etc). Hope this helps. As noted above - "tare" is certainly possible if that is what you meant.

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.

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.

You turn the button on/ off, have it on then you choose press Unit for gram or press again for kg,press again for OZ, wait until the screen appear all 0.00 before you place your item on the scale,other wise it wouldn't work. This scale weight up to 5 kg. Check battery once a while.

I have not built this model yet but have bought this scale to do that very thing. YouTube has video on how to do it with this model.

The same happened to me! I returned it directly to the manufacture if you're still on time to return it DO IT!! and buy a different scale! Hope my advice helps you! GL

The scale is self-calibrating (simply step on ,off and on again). It needs to be on a level hard floor (not carpeted). It is more accurate and consistent than several previous scales that we owned (both digital and analog). If it not as described, the unit might be defective. You can talk to customers' service which is supposed to be excellent per other veviewers.

I have no way to verify accuracy since I don't have nist traceable standard weights. Precision seems OK. I have noticed that the scale sometimes doesn't want to zero. I'll turn it on and it moves away from zero (I have seen it go higher and lower). When it does this the zero may wander as much as 10 lbs. Eventually the scale stabilizes. I have not contacted the mfg. I find this annoying but am willing to live with it since it rarely happens.

Hi there, I wish I could help you , but I'm not sure how its done. The scale I have doesn't go to that measurement. Sorry !!!

On the backside of the scale you'll see a small button. Simply depress and hold the button while viewing the display until the units of measure change.

Get the calibration weights. They are an absolute MUST with inexpensive scales. This one is pretty accurate. I reweighed the same mass 5 times and got the same reading each time.

Sounds like you have a faulty scale...I suggest returning it for replacement. This has never happened with mine.

I discovered after I had the same issue that I needed to press the scale quickly and let it "set". When you see the zero's on the display, you can then step on the scale and it will calibrate your weight. Hope this helps.

The instructions say it needs to recalibrate. That may be a hassle. But it is a good scale.

The little paper manual that came with the scale is not clear. It says that the conversion button is on the bottom of the scale. It's not. It's on the back of the scale. It's shaped like a very small half paper clip. Just push down on it and it will convert.

I'm not aware of a calibration function to it. It's simply quite accurate out of the package.

From the owner's manual:IX. Calibration Adjustment 1. Press the ON/OFF key to turn the scale on. 2. Press and hold the MODE key for three seconds until the display shows "CAL" then release. 3. Press the MODE key again, and the LCD will flash the first calibration weight. Place the required weight on the middle of the platform 4. The LCD will flash then flash the second required calibration weight. Place the required calibration weight on the middle of the platform. Skip this step for model ACP-500. 5. The LCD will display "PASS" and return to normal weighing mode. Calibration is complete!According to the manual, you will need both weights. From the owner's manual:IX. Calibration Adjustment 1.
