how do I calibrate the scale?

The scale comes pre calibrated with a certificate of calibration. However if you still want to check accuracy just use a dime or nickel.

I purchased a 100g calibration weight which I use once every month to ensure that the unit is measuring accurately. Since this is not a high end scale, I would recommend doing it.

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.

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.

You can order calibration weight at AMAZON.com. They have various sizes of weight to choose from.

Stand in front of the scale as if you are stepping up to weigh. Put your left hand over the left end of the measuring scale. You should feel, and then see, the end of a screw that can be turned with a regular screwdriver. This screw adjusts the balance. You should turn it either right or left until the balance bar on the right side is level between the two sides. I forgot to mention that you must ensure that the weight is set right on the zero point. I hope this helps. I haven't adjusted mine since I first set it up a few months ago.

The scale will return to zero after you remove the package. There is also a tare button that will calibrate the scale back to 0 when you press it.

I guess by using a known value, like the calibrations buffers, 4.0 or 7.0. It's like using a calibrated weight to check a scale

Hold the button on the right in as you drive the vehicle in a couple of figure 8 circles! That should calibrate it.

Press and hold the scale button. once it shows on, then check tire pressure. When you adjust pressures, press scale it should reset to read again. while the gauge is off tire, you can calibrate the gauge by pressing both buttons again to let it calibrate. Hope this helps. J.R.

it can not be calibrated. We are using it in medical office to weigh people in exam rooms rather than hallway scale.

Thank you for your message John. I would like to direct you to Health-O-Meter to answer your question regarding the calibration process. Their Tech Support division can be reached at 800-638-3722. They can assist you regarding any questions you may have on recalibration. The scale can be used on carpet, but I would recommend placing something underneath the scale to stabilize it like a piece of plywood. Please let me know if you need any additional assistance. Thank you very much!

Mine is not calibrated and is way off. They expect me to find a 5 lb. weight somewhere in order to calibrate the item.

Buy one of the new electronic scales. Less meshing around and probably more accurate and take up less space. Pounds and inches.

I found nothing in the instructions on how to calibrate. We just installed ours and so far it's accurate. Time will tell.

I tested the scale with 1 sheet of 8.5x11 of paper. It did not show any measurement. With two sheets it read .006kg and .2oz, with three sheets .0010kg and .3 oz, hope that helps. The scale will calibrate and zero itself every time you turn it on. I'm happy with my purchase. I measure letters and packages on it.
