Legal for trade scales go through stringent tests to be able to get the NTEP approved certificate. Although these tests cover a wide set of features of the scale the approval is not given to the scale in general. The approval is given for a given set of units and a given set of weighing modes. Now the units for a sales transaction do not change very often but once in a while you may get an unusual request and you may wish to comply. At such a time you should know that the scale is approved only for some units of measurement. The same applies to the modes of operation. A scale may be able to perform as a simple weighing scale or it may be able to work as a price computing scale and also as a counting scale. But its use as per law is limited to only those modes for which it has been granted an NTEP certificate. If you are using the trade scale for direct sales then you may need to have two displays. This way both you and the customer can see the reading at the same time and be satisfied that the weight has been measured in a fair and honest manner. If you have bought a legal for trade scale that is marked as not for direct sale you will need to add an additional NTEP approved indicator to it. The use of a NTEP scale makes it easy for businesses and people to be able to trust one another. For people buying digital scales it is also a great way to assure themselves of the great quality of the product that they are buying. And so today a wide range of such scales is available in the market. When choosing from this wide range of products you should take care that you don't just choose a product that suits your needs but also that it is approved specifically for the modes and units that you want to use for your day to day weighing.
