How to easily troubleshoot weighing scale issues
Before you decide to call in a technician, some things that can be easily fixed!
Listed below are a few things to check before making that repair call:
- Are the scale cables all connected and in good shape?
A common issue is when the cables become disconnected or damaged from scales being moved, improper handling, forklifts, or rodents, etc. If your weight is drifting up and down and all over, look for loose cables where they meet the indicator, where they meet the scale, and any power cables. Check the cables that connect the load cells underneath the scale platform and making sure no cables have been pinched, are frozen, in water, or severed completely. This is more relevant for bench scales, floor scales or truck scales. - Is there a build up of ice, dirt or something that is touching the scale underneath it when it is loaded?
When there are objects or material buildups beneath the scale platform, it supports the platform when there is weight applied and so whatever is being weighed, will be lighter then it is. This is why it is important to keep it clear underneath the scale platform and inspect the floor and base of the wall before you move a scale onto it to make sure nothing will prevent the scale from moving freely. This is also more relevant for bench scales, floor scales or truck scales. - Are all the feet touching the ground and is the scale level?
In most cases each corner has a load cell and weight should be evenly distributed throughout those 4 corners. If the weight is not evenly distributed you can have weight discrepancies or even damage load cells if too much weight is applied to one of the load cells. This is important for lab balances or instruments that require really high accuracy. - Is your scale plugged in and switched on?
It seems silly – but it happens!
Good preventative maintenance habits
Scale indicators are highly sensitive to voltage spikes so make sure you unplug your scale during storms or when powering on/off a generator. Highly accurate lab balances are also susceptible to changes in air and air movement so turn off any fans, or move away from vents and have a draft guard installed on the scale. If you ensure a level, clean, and dry environment for your scales – you will have the most accurate measurements.
There are many issues that can affect these weighing instruments. Just a quick check can prevent any maintenance costs!
Knowing where to look is a good place to start and having all the information can help diagnose and repair the scale faster.
