There are numerous types of digital scales, ranging from small ones for food and other light objects to larger scales that people weigh themselves on. If a digital scale is not calibrated, and therefore inaccurate, it becomes useless. Making sure your digital scale is calibrated is an important part of the necessary care and maintenance for keeping your scale in good working condition.

Preparing for Calibration

Turn on your digital scale and wait 30 seconds to 1 minute. Make sure your scale is using the proper power supply, which will normally be an AC adapter or batteries. Locate the calibration button on your scale. Depending on the type of digital scale you are operating, the calibration button can be labeled in various ways. The most common calibration labels include: "Function," "FUN," "CAL," "MODE," or "LB/KG." When you've got the right button, hold it down until "0", "000" or "CAL" shows up on the screen. Once this shows up, your scale should be ready for calibration.

Calibrating

Your digital scale should have come with a specific calibrating weight. If you can't find this calibrating weight, you can purchase another one from the manufacturer or the store where you originally bought the scale. Once you have the weight, place it on your scale for about five seconds or until your scale's digital screen reads "CAL," "0," or "END." When this appears it means your scale has registered the weight and has calibrated itself. Before using your calibrated scale, turn it off and wait at least 1 minute before turning it back on. Your scale is now calibrated and ready to weigh things.

Troubleshooting

If you are having trouble calibrating your digital scale, you should read the scale's manual for model-specific instructions. If you don't have access to the manual, try searching online. Oftentimes electronics manuals and instructions are posted online for consumer convenience. If this still doesn't work, take your digital scale to an electronics shop and have someone guide you through the calibrating process. It could be that your digital scale is malfunctioning, and you may have to send it back to the manufacturer for a new model or a rebate.
