Directions to Calibrate My Digital Scale

Calibrating a scale before it is used is quite possibly one of the most important steps that an owner can take to ensure that their readings are accurate. What is calibration? Calibration is basically the comparison of the reading that your scale gives you against a standard value (an object with a weight that you are already sure of), and the adjustment of the scale accordingly. An improperly calibrated scale is essentially useless, as it will give you the wrong results every time you use it. If you have recently purchased a scale or it’s simply been a while since you last calibrated your digital scale, follow the instructions below in order to make certain that your scale is in proper working order.

The first step that you’ll need to take in order to calibrate your digital scale is to turn it on, and then let it warm up for a number of minutes. I know this seems obvious, but if you’ve been experiencing problems with your scale, you do want to make sure that the batteries are fresh or that it’s firmly plugged in, and that it has had an opportunity to adjust to the temperature of the environment. The value of this first step should not be underestimated.

After the power source of your scale has checked and your scale has been turned on for some appropriate time, use the on screen menus find and press the calibration button until your scale gives you some sort of visual acknowledgement on its screen. The calibration button or setting will vary from scale to scale, but can most likely be found by pressing the function button, the mode button, or a button that reads “CAL”. Don’t forget that if you’re unsure of which button to choose, there’s no need to panic. The manufacturer manual can provide you with this information.

Once you’ve turned on your scale and held down the calibration button for a sufficient length of time, your scale should automatically go into calibration mode. Once it enters calibration mode, your screen will either display “CAL” and then a number or it will simply display a number in order to let you know that it’s ready to go. More advanced scales will actually give detailed instructions on the screen. When the aforementioned number appears on your screen, place the appropriate calibration weight on the scale, and allow it to be weighed for 3 to 5 seconds.

If you have lost your calibration weight, you can purchase another one either from your digital scale’s manufacturer or from a vendor that sells digital scales. Alternatively, your scale may ask you for a 100 gram weight. If this happens, you can use a standard stainless steel test weight, or a combination of weights that add up to 100 grams.

After the calibration weight has rested on the scale for 3 to 5 seconds, press and hold down the calibration button one more time. Your scale should give you some sort of final visual acknowledgement that will let you know it has finished its calibration. Your screen will likely read “CAL”, “END”, or “0″. Congratulations! After following these steps, your scale should be calibrated and ready to use.
