how do you calibrate this scale

Hi Christa, To calibrate the scale: Press "MODE" and "ON/OFF" at the same time to turn on the scale and release the keys until the LCD shows ISN. When ISN is stable, press "ON/OFF", the LCD will show "30lb". Then put a 30 lb weight set unto the scale and press "ON/OFF" again. LCD shows "PASS", the calibration is finished.

The scale auto-calibrates when it is picked up, moved or changed batteries so it adds 8+ pounds for the first weight. You just have to step off, and step back on and it will show your true weight.

I personally do not use calibration weights as 100% accuracy is not required for the reason I use the scale. That being said, if one requires accuracy, I would think 3 weights would suffice. One each at the low, middle and high points of the expected range of measurement. I hope this helps you.

It should be easy to calibrate (and never assume any measuring device is "factory calibrated"!). Just put an empty container on the scale, press the tare button. Scale should now read 0. Pour a cup of water and the weight should be 8.3 oz.

I've never tried it, but have you checked with the USPS to see if they have any calibration weights on site? I'm sure their scales, like all scales, have to be calibrated regularly. You could take it to them and see what they say. I live in a rural area and the local branch is never very busy, so I'm sure they would help me. A busier location may not be as helpful.

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.

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.

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 !!!

What the manual is saying if you calibrate this scale at say 100 ft above sea level and than use the scale at 10,000 ft above sea level you will need to recalibrate the scale.

Yes it can be re-calibrated if necessary. When I do it the scale asks for a 1000.0 g weight. I don't have any so I just check it with the smaller weight set I have. You can buy the weight on ebay for 17 USD or so. Wish they stated this in the product description. Good luck. Joe

I answered this incorrectly before. It seems when the scale is moved it does need to be re-calibrated so to speak. It won't be accurate at first weigh, but get on it again and it will weigh correctly.

Mine is always 4 pounds off and I don't know how to fix it. It zeros itself each time I use it , but then is 4 pounds off one way or the other. I think it is just a bad scale. I am going to get a different scale from a different company. Sorry I couldn't help.

There is no initial calibration needed and I don't find anything regarding instructions on how to calibrate it should there be the need to in the future. I am assuming that since it works as most digital scales do, measuring changes in electrical resistance distributed to load cells, calibration is performed at the factory and would need to be performed by the factory in the future if there was a need to do so. I have had other digital scales which operated the same way and lasted for many years. It measures the same as a mechanical scale I have so I believe it is accurate from the factory. The only way to tell for sure is to locate a standard and periodically check to ensure it is calibrated against that standard.

I checked the users guide and do not see any information about calibration of the unit. There is a support number you can call.

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

There is no need to calibrate the scale before use. I use the scale to weigh out coffee for my morning brew. The measurement readings change with increases in weight. From 0-200g you're able to measure to the nearest hundredth of a gram (0.01g). From 201-500g your able to measure to the nearest tenth of a gram (0.1g)From 501 - 2000g you're able to measure to the nearest gram (1g)Hope this helps.

3" x 5" x .75". Scale comes with a weight that can be used to calibrate at any time.
