Frequently Asked Questions

As a weighing scale manufacturer and supplier in the medical, industrial, veterinary and retail sectors we get a whole host of questions sent to us.
If there is anything you’d like to know, we’d love to hear from you - so please get in touch with us!
We get questions on a range of topics from industrial businesses - but some get asked more often than others.
Here are some of the topics we get asked about most often:
What is the difference between Trade Approved and Non-Approved?
A Trade Approved scale is a weighing scale which has been legally tested and approved for the process of selling goods.
In other words, if money is changing hands as a direct result of the reading on the scale it must be Trade Approved.
Many Marsden scales are Trade Approved, but not all of them. If the scale is used for check weighing, for example meat in a butcher’s shop, it doesn’t need to be Trade Approved - unless it is used for front-of-house weighing.
More information can be found in this blog post.
What is a Class III Approved medical scale?
When scales are used to calculate prescriptions or monitor health signs then it needs to be Class III Approved - with the Class approval denoting how accurate the scale is.
Scales that do not have the accuracy required can have severe consequences in the medical sector. So, since the 2003 NAWI directive, it has been strongly recommended that medical scales are Class III Approved. This white paper explains more.
Class III Approved medical scales, like approved industrial scales, are subject to far more stringent testing than standard weighing scales.
What are Capacities and Graduations?
The capacity of the scale is the maximum weight of the good which the scale can measure.
Graduations are the increments to which the item is weighed - in other words, how accurate the scale is. The lower the graduations, the more accurate the scale is.
More information on capacities and graduations can be found in our helpful glossary.
Calibration is a definition used to determine the accuracy of a weighing scale. All Marsden scales are calibrated before they leave our warehouse to ensure they are weighing correctly.
A calibration certificate is a record of when the last calibration check took place. This helps for traceability and peace of mind. This certificate will also show if the scale has lost any accuracy over a period of time.
To charge your scale via the mains, a Marsden adaptor is required.
If the scale/indicator has one display screen it will use the DP-2400 adaptor or DI-28 adaptor. If the scale/indicator has two display screens it uses the DP-3800 adaptor.
Marsden scales with the DP-2400 indicator are compatible with the V2 battery packs. If the Marsden scale has DP-3800 indicator, it requires a V3 battery packs.
A comprehensive list of scales, the adaptor and the battery pack required is below:
