10 Steps to Maintain a Commercial Weighing Scale
Service it regularly
This is ABSOLUTELY NECESSARY. A Weighing scale is just like any other piece of Machinery. It needs Maintenance and care. If you donot have the time to do it, you can outsource this to Hindustan Scale Company (HSCo) with an AMC plan. This includes four preventive maintenance visits of the weighing scale and the Government Stamping costs.
Change the battery at least once in Two years
The batteries that HSCo uses in weighing scale will give you 465 cycles of complete charging and discharging cycles. This means that you can completely charge and discharge the battery 465 times, before the battery starts losing its power to hold the charge. In short, the more you use the battery, the more frequently it will have to be replaced.
If you use the scale in an area which has frequent power cuts, then you would need to change the battery preferably once in a year. On the other hand, if you use the scales continuously on power supply and rarely on battery, you may change the battery once in two years.
We would recommend that once in a week, let your scale run completely on the battery until it discharges. Then plug it in to let it charge as usual. This will keep the acid active in the Battery.
If your battery is not working and you use the scale only on light, you would probably think that its ok. Well its not. The reason is that there are various ICs in the motherboard of the scale that need power even when the scale is switched off. The batter does this. If your battery doesnot work, then your scale may show you erratic weights.
Stamp it by the Government once a year
Well, if you don’t do this, you are liable for a fine of upto 25,000/-. The stamping would be a fraction of this cost. Why do you want to risk it? It’s not worth it.
Also, before being verified by the Legal Metrology Department, you scale will be thoroughly checked by the Inspectors. They will reject the scale if it shows you the wrong weight. Atleast that is the time. If not earlier, that you will get to check the weighing scale.
If you are covered under the HSCO – CARE Plan, then HSCo will take care of the Legal Metrology Stamping and you donot need to worry about it. For the rest of the guys. Please be careful of the fine. Its really steep.
Check the scale with a stand weight at the start of the new day
Take a weight that is approximate 10% of your scale’s weighing capacity and keep it handy. Check the weight at the start of each day when you start using the scale. THIS IS ABSOLUTELY ESSENTIAL FOR PRECISION SCALES, because slight humidity and pressure changes can change the reading of high precision scale. Invest in Weights. It will pay for itself within- months.
Keep it away from Moisture.
Moisture affects the motherboard and all electronic components of the weighing scale. The more the moisture, the more the problems in the weighing scales. I have written a blog on how to protect your weighing scale from moisture. Read the blog here.
Just a note. All HSCo Weighing Scale use the Blue Whale Technology Motherboards (BWT) that are moisture resist.
Always ensure that the scale has a constant power supply and there is no fluctuations in power
Erratic power is bad for any electronic Device. An electronic Scale is no exception. Always use a power supply that gives a constant power supply. IN cities, you may get a stable supply. In smaller towns the power fluctuations are more common. Same is the case when its an MIDC area or an area where there is a community generator.
HSCo scales use an internal power stabilizer chips that would be able to filter out most of the peaks and troughs in the power supply. However, its advisable to use a spike guard
Donot overload the scale
This is an Absolute No. Overloading will rupture your Loadcell, and your weighing scale will become useless. NEVER EVER overload the Weighing scale.
HSCo Scales use Loadcell that are rated 100% its overload capacity. That means that if there is a 100 kg weighing scale, we use a 200 kg Loadcell to manufacture it. And the Loadcell also has a 100% overload capacity. Meaning that the 200 kg Loadcell can tolerate 400 kg of force on its application point. However, we still recommend that you donot overload the weighing scales.
Don’t bang your product on the scale
The Loadcell (even known as the sensor) of the weighing scale is rated in terms of KgF. This means it measures force rather than weight. So when you bang something on the Weighing scales plate, the equivalent amount of force is transmitted to the Load Cell. If the Force is more than the rated maximum force, then the Loadcell will rupture and you will have to replace it.
Charge the battery regularly
The battery gives a constant power supply to all the processors and components of the weighing scale. Like your mobile phone, it has to be charged regularly.
Keep your Weights and Measures Certificate Handy,
As per law, you have to display the Legal Meteorology Certificate prominently where the weighing scale is being used. Else you are liable for a fine. So if you have not already done, put the certificate in a accessible location where the customer and user of the weighing scale can see it. Keep the certificate like this, will also constantly remind you of when is the stamping due date.
