How to properly calibrate an electronic scale - Our complete guide

Whether it is for domestic, professional, or specific use, an electronic scale must provide reliable measurements. However, over time or after a shock, it can lose accuracy. It is therefore essential to calibrate it regularly. Here is how to do it in a simple and effective way.

Why calibrate an electronic scale?

Calibration ensures that your precision scale shows an exact weight. Without it, you risk obtaining incorrect results which can be problematic, especially for:

• Preparing recipes that require great precision.
• Conducting experiments or laboratory analyses.
• Measuring costly or sensitive substances or ingredients.

In short, a poorly calibrated scale can distort all of your measurements.

What do you need to calibrate your scale?

To succeed in the calibration, equip yourself with:

• Calibration weights (standard weights) suited to the capacity of your scale.
• User manual of your scale (recommended to know the procedure specific to your model).
• Flat and stable surface to avoid any measurement errors.
  
  

Steps to calibrate an electronic scale

1. Turn on and stabilize the scale

Place your scale on a flat surface. Turn it on and let it adjust for a few moments to the ambient temperature.

2. Start the calibration mode

On most models, press the "MODE" or "CAL" button until the calibration mode activates. Consult your manual if the button is different.

3. Place the standard weight

When the screen displays the calibration value, gently place the standard weight on the scale. Wait a few seconds for the scale to adjust the measurement.

4. Validation

The scale will display "PASS", "END", or the exact value if the calibration is successful. Remove the weight and check that it returns correctly to zero.

Some additional tips

• Avoid calibrating the scale near a source of vibrations or draft.
• Always handle the standard weight carefully to avoid altering its accuracy.
• Repeat the operation regularly, especially after moving it or a shock.
  
  

By taking the time to properly calibrate your scale, you ensure reliable and accurate results for all your needs.
