Digital pocket scales are often used for business, shipping, cooking, and more. You will likely need to recalibrate the scale after every 4-5 uses to get accurate readings. You can calibrate your digital pocket scale by cleaning it and following the calibration steps while using weights, coins or household items.

To step

Method 1 of 3: Finding the right surface

  1. Place the scale on a firm, level surface. This is the best place to calibrate your scale. Gently push the surface several times to make sure it doesn't move or is unstable. If you are unsure whether the surface is smooth, use a spirit level to check or place a small ball or pencil on the surface and see if it rolls off.
  2. Place one or two mouse pads on the surface of the table. The mouse pads will act as "dampers" to reduce vibrations that could interfere with the scale's calibration. If you don't have a mouse pad, use an underpad or rubber oven gloves.
  3. Place your scale on the mouse pad and turn on the device. The location of the start button will differ depending on the brand of the scale.Normally it is located at the front of the scale, along with the rest of the buttons, but it can also be a switch located at the back of the scale.
  4. Press the "Zero" or "Empty" button on your scale. It is located on the front of the scale where the weight is displayed. Wait patiently for the scale to clear all data from previous measurements. This may take a while, but your scale should display the weight "0.00" after this.
  5. Verify that your scale is in calibration mode. The guidelines for putting your device into calibration mode will vary depending on the brand of your scale. Sometimes there is a button or a switch or you have to press some buttons. View the scale's manual or search online to find out how to put your scale into calibration mode.
    • Often the manufacturer's website contains information on how to calibrate specific models.

Method 2 of 3: Calibrate your scale

  1. Select a suitable weight to calibrate with. There are a few options for weights, including adjustment weights specially designed for this purpose, coins or household items.
    • A calibration weight is a solid object that usually does not contain air holes and helps determine the accuracy of your scale's measurements. Calibration weights are available from 1 mg to 30 kg.
    • If you don't have calibration weights, you can also use a chocolate bar, as the packaging weighs very little.
    • An alternative is to use coins:
      • Coins of 20 cents weigh exactly 5.74 grams.
      • 50 euro cent coins weigh exactly 7.80 gr.
      • 1 euro coins weigh exactly 7.50 g.
      • 2 euro coins weigh exactly 8.50 g.
  2. Place a calibration weight, a coin or a household item on your scale. As long as you know the exact weight of the object, you can use it to calibrate the scale. If you don't know the exact weight, don't use it to calibrate your scale as it can damage the scale if the object is too heavy.
  3. Enter the mass of your chosen weight on the scale and press the "Enter" key. It is best to start with a lighter weight such as 5 or 10 grams. The scale will store the data and use it to weigh other items.
    • For example, enter "8.50 grams" if you are using a 2 euro coin as the adjustment weight.
    • If you are using a chocolate bar or another piece of food, the mass is stated on the packaging. Make sure to enter the exact weight or round it up to the next number your scale can measure.
  4. Add weights to the scale until you reach the maximum weight limit. Once you approach the limit, check the scale to see if the weight is the same as the known weights you have placed on it. This limit differs from scale to scale, but information about it should be in the manual or on the manufacturer's website.
    • If you are using coins, calculate the number of coins you need to reach the maximum weight limit. You do this by dividing the maximum weight limit by the weight of the coin you are using.
  5. Adjust the calibration up or down with the buttons on the front of the scale. If the weight on the screen does not match the expected weight, you can adjust this difference and have the scale "tell" the actual weight of all weights.
  6. Switch off your scale if you need it. Once the scale has been calibrated, you can switch off the scale. You can do this to return the scale to normal weighing mode when there is no switch to enable calibration.

Method 3 of 3: Store and clean your scale

  1. Keep your scale in a safe place. When not in use, the scale should be stored somewhere to prevent accidents that could affect calibration. Good storage can be done on a high rack or in a closed cupboard.
  2. Brush the surface of your scale with a small brush before weighing anything. This will help to remove any debris from the weighing surface. Make sure you are careful not to push on the scale as this can damage the strain gauge which helps to take accurate measurements.
  3. Rub your scale with a slightly damp and soft cloth. Rubbing the surface of your scale very gently will remove any debris that your brush may have been missing. Make sure the cloth is only slightly damp as water entering the scale can cause permanent damage.
    • If you need a sanitized surface, you can use a drop or two of normal dish soap on your cloth to clean the weighing surface.
  4. Check the battery compartment. If you are using a scale with batteries, open the battery compartment, remove the batteries, and gently wipe the inside of the battery compartment. While the battery compartment is open, you can choose to replace the batteries, as malfunctioning batteries can affect the scale's performance.
  5. Use a knife, blade, or pin to remove caked-on dirt. Kitchen scales will often have dried-on dirt on the weighing surface that cannot be removed with a cloth. Gently scrape that area with a sharp object to remove the dirt and return to a clean weighing surface.

Tips

  • Please refer to your pocket scale manual before cleaning and calibrating it so that you are aware of any specific guidelines or warnings. The manual may contain valuable tips that are relevant and specific to the model of your pocket scale.
  • You must clean the scale after each use.

Warnings

  • Never immerse your digital pocket scale in water and never use running water to clean your device. This can permanently damage the measurement components in the scale.
