What is the capacity and accuracy that I will need?

What are the lightest and heaviest items you will be weighing? How accurate do you need the weighed item to be – for price determination, as an ingredient or component, as a comparison, or for transportation.
Depending on the accuracy you require you may need to purchase separate scales to weigh your lighter and heavier items.

Will I be weighing and packing goods that are getting sold to a customer?

If the answer is “yes”, then a Trade Approved Scale is required.
It is a requirement of the Fair Trading Act that where goods are offered for sale to a customer, with the sale price depending on the weight of the item sold, a “Trade Approved” scale must be used to determine the value of the sale. Trade Approval is given by the Ministry of Consumers Affairs, and every “Trade Approved” scale has a TMU approval number.

Will my scale be involved with direct counter sales with the public?

If you are weighing goods in front of a customer at the time of purchase, then you are required to have a rear display on your scale, so that both you and the customer can see the weight of that item.
For retail outlets, Trade Approved Price Computing Scales allow you to weigh the item, input a price, and the scale will calculate the individual sale amount.
Scales can also be linked to a computer and/or a cash draw to provide a complete transaction record (including a Tax Invoice for the customer).

Do I need auxiliary equipment?

In some situations your scale will be linked to other equipment you use in transacting your business.

  1. For retail purposes, perhaps a computer, cash register and/or printer
  2. For commercial or industrial purposes, perhaps a remote display board, a driver control station, external devices (relays, triggers) or a computer management system.
