To read an article about weighing and weighing machines
Has two detachable lids, an outer lid that forms a cover over the entire scale, and an inner lid over the weighing platform. Turn either lid upside down to use as an additional weighing platform, you can then weigh piles of items.
Counting, for counting small components (must all be the same weight). Place 25, 50, 60, 75 or 100 of the components on the weighing platform. Press lots of buttons. Remove the items. Now you can place (or pour onto the additional weighing platforms) dozens or hundreds of the components, and instead of weighing them the display will show the quantity.
Backlit display can be set to turn on (good in bad light) or to stay off (good for battery-saving) or to stay on for 15 seconds each time you weight an item or press a button.

- Troy ounce (ozT) for gold and silver (and was once used for letters and parcels)
- grams, metric. Today everyone weighs gold in grams. But dealers tend to weigh silver in Troy ounces
- ounce (manufacturers call it, "English Ounce", correct term is Ounce Avoirdupois) for food
- Pennyweight (dwt), pre-decimal system, still used in USA
- Carat (ct) for gemstones and diamonds, not to be confused with carat as gold purity)

Guarantee
1 year. This covers manufacturing faults only, it excludes normal wear and tear, bowls, trays, finishes, clasps, hinges, feet, AC adaptors and batteries; it also excludes being overloaded / dropped (e.g. error messages EEE, 0-Ld, or OUEr). The guarantee is invalid if the scale shows signs of foreign material (e.g. residues of herbs, chemicals, corrosion, spilt tea). After 1 year you must pay the postage both ways.
Inaccurate readings can be fixed by calibrating the scale, this is something that is very easy for you to do yourself with , i.e. a 2Kg and a 1Kg, or three 1Kg weights. The weights are not included with the scale. Giving inaccurate readings does not mean it is broken - all electronic measuring devices need calibrating every now and again, see .
