Troubleshooting Ideas for Digital Scales

Digital scales are a convenient tool for weighing items. However, they can sometimes malfunction, giving incorrect readings. If you depend on the accuracy and precision of electronic weighing scales, it is essential to ensure that it is functioning optimally and properly.

If you are in the food business and your scale is malfunctioning, it can be frustrating for customers trying to get an accurate weight of their items. Fortunately, there are some things you can do if you find yourself in such a situation.

Common Errors and Quick Fixes for Digital Scales

1.    The scale readings are inaccurate.

If the digital scale is not properly calibrated, it will give inaccurate readings. Most of these scales come with a specific weight that you can use for calibration.

If the digital scale is not levelled on the ground, table or counter, it will also give inaccurate readings. So, make sure that it is placed on a stable and sturdy stand or area. Lastly, if the digital scale still gives inaccurate readings, you may need to replace the batteries.

2.    The scale doesn't turn on.

In most cases, when your scale doesn’t turn on, it can be fixed by simply replacing the batteries. If they have been replaced but it still doesn't work, a wire has likely come loose or there is another problem with the electrical connection within the unit. In this case, it may be best to consult your weighing scale provider.

3.    The display is blank.

If you are using a battery-operated scale, check the batteries. Generally, if the batteries are low or need to be replaced, that could be why the display is blank.

If you are using an electric-powered scale, try resetting its system. To do this, simply unplug it and then plug it back on. This should cause the digital scale to reboot and hopefully fix the problem.

If neither of these methods works, you may need to contact the manufacturer for further assistance.

4.    The scale is displaying error messages.

The quick fix for scales that display error messages is similar to a blank display. Simply check the batteries and replace them if necessary. You should also try resetting the system and this should clear the error messages.

5.    The buttons on the scale are unresponsive.

If your digital scale is unresponsive, first, you'll want to make sure that the batteries are properly installed and that there's no corrosion on the battery terminals. If the batteries seem to be fine, then you'll want to check the scale's button contacts.

The buttons may need to be cleaned with a cotton or soft cloth. If the problem persists, you may need to replace the scale's button board. Once you've done this, your digital scale should be working properly again.

6.    The scale is vibrating excessively.

What do you do when your digital scale starts vibrating excessively?

Just like any other troubleshooting for electronic devices, the first line of defence is to check and replace the batteries and see if that solves the problem.

If the vibrating issue pursues, it's possible that something is stuck in the mechanism. Try to gently tap the scale on a hard surface to dislodge whatever may be causing the issue. If all else fails, consult the user manual or contact your provider for assistance.

7.    The batteries drain quickly.

Digital scales can be frustrating when they suddenly stop working correctly, and the battery drains quickly. To fix this, check the battery compartment for any corrosion or damage.

If the batteries are leaking, they will need to be replaced. Then clean the contacts on both the batteries and the digital scale. Use a cotton swab dipped in rubbing alcohol to remove any dirt, grease, rust or battery leakage.

8.    It malfunctions due to excess weight limit.

Digital weighing scales can sometimes malfunction if they are overloaded with weight. Some scales include an auto-shut-off feature when overloaded. This helps prevent any further damage to the device.

If your scale does not have an auto-shut-off system, simply remove the load from the scale. Then switch off the unit and turn it back on after a minute or so. This should solve the malfunctioning problem.

If the scale still isn't working properly, you may need to reset it. Remember to check the load limit of the scale in the user manual to prevent this from happening. Most digital scales have a maximum weight limit of around 100Kg.

9.    The scale is giving inconsistent readings.

When digital scales give inconsistent readings, it is often because the sensors are dirty. To clean the sensors, unplug the scale or remove the battery. Then, use a soft-bristled brush to remove any debris from the sensors. Once the sensors are clean, reconnect them to the power source and turn on the scale.

If the scale still gives inaccurate readings, try calibrating it. Most digital scales have a calibration function that can be accessed through a menu. Once the calibration is complete, your scale should give accurate readings.


Digital scales play an essential role in many applications. It helps if they are functioning to the fullest. If you encounter any issues, try the quick fixes mentioned above, and your scale should be fine.
