Most scales and weighbridges don't stop working without warning. They give signs first: a reading that won't settle, a number that looks a bit off, a driver who argues about his weight. Catch these early and a service is usually a quick fix. Ignore them and the same fault can turn into a replaced load cell and days of downtime.
Here are seven signs to look out for.
1. It won't return to zero
With nothing on the deck or platform, the indicator should read zero. If it shows a few kilograms, or the number keeps creeping, something is wrong. Common causes are debris touching the deck, moisture in a load cell or junction box, or a damaged cable.
2. The same load weighs differently in different spots
Put the same load at the front, the middle and the back of a weighbridge deck, or in each corner of a platform scale. The readings should match. If they don't, one load cell is likely reading differently from the others, or the deck is binding somewhere.
3. The reading jumps or flickers
A stable load should give a stable reading. A display that keeps jumping between values often points to a loose connection, water in the junction box, or electrical interference.
4. Error messages or a dead display
An indicator showing error codes, or switching off and on by itself, needs attention. Sometimes it's just the power supply. Sometimes it's a sign of a bigger electrical fault that can damage the load cells if it's left alone.
5. It's been through a storm
Lightning doesn't have to hit the weighbridge to damage it. A strike nearby can send a surge through the cables and into the load cells and indicator. If your site has had a heavy electrical storm, have the system checked even if it seems fine. Damage often shows up weeks later.
6. Customers are disputing your weights
When suppliers or customers start questioning your weights, you need proof that your scale is right. A verification with certified test weights and a dated certificate settles the argument either way, and protects your reputation.
7. You can't remember the last service
If nobody on site knows when the scale was last serviced or verified, or the last certificate is over a year old, it's due. Regular servicing is far cheaper than the cost of weighing wrong for months without knowing.
