Wheel pads are among the most widely used portable truck scales across many essential Alberta industries. From hot-shot delivery trucks to construction fleet vehicles, wheel pads help operations to maintain consistent, reliable measurements day in and day out. At Accurate Scale, we regularly repair a wide range of wheel pad scales.
In this short blog with Accurate Scale, let’s break down some of the most common indicators that your wheel pad scale needs a repair. Proudly Canadian, we’re your local scale experts for scale repairs in Canada. Let’s dive in!
#1: Error Messages
An error code is your scale’s way of trying to tell you there’s an irregularity. Error codes can happen for a multitude of reasons. Causes can range from a loose connection to a larger issue, such as a malfunctioning load cell. In many cases, it’s possible to receive an error code for issues such as overloading and other incorrect uses. The importance comes when the error message becomes a repetitive pattern. If you consistently see an error code on your scale while it’s in proper use, it should be taken to a technician right away. Common error messages can be about:
- Weakening or failed load cells
- Low voltage
- Physical instability
- Failing connections
- Internal circuit board failures
Additionally, not every error will be as visually obvious as a bright red ‘overloaded’ warning. Keep an eye out for more subtle indicators as well, such as display flickering.
#2: Readings are Slow
Wheel weigh pad readings are done by loading each wheel onto a pad. The weight’s overall strain is then measured by the internal load cells. These changes in resistance are then converted into an electrical signal, which is displayed on the indicator. While the exact reading speed depends on the specific scale model, this entire process should take no more than a few seconds. Scales with failing components may take much longer to display readings or exhibit jumpy, inconsistent weight stabilization. Sometimes, it can also mean it’s in need of a comprehensive calibration servicing. Regardless, it’s a clear sign that the scale should be brought to a reputable scale technician for diagnostics or scale repairs in Canada.
#3: Wear on Cables and Load Cells
While wheel well pads and other portable truck scales are built for rugged durability, wear and tear can still occur over time. From snagged cables to dents on the pad surfaces, these damages can ultimately lead to inaccurate readings if left unrepaired. For example, broken cables can lead to incorrect readings by failing to transmit electrical signals from components to the cables properly. Even small frays or punctures can completely interfere with the signal.
If you notice any physical wear symptoms on your scale’s components, it’s best to repair it immediately.
#4: It Randomly Powers Off
Random shutdowns are a telltale sign of internal component failure. When in active use, your wheel pad scales should never shut off unexpectedly. This could indicate a potential issue with wiring, loose connections, or other internal component issues caused by short circuits. If your scale shuts off on you, whether once or multiple times, it’s likely due for a visit from a licensed scale technician.
Another warning sign that a wheel pad is in dire need is when the scale powers up slowly. Often, this means that something is struggling within the scale’s internal boards or experiencing a power supply issue.
