Technical Specification
RESOLUTION / CAPACITY: 50g / 0.001g.
Also switchable to ounces (oz), Troy ounces (ozT), pennyweight (dwt), grains (gn) and carats (ct)
- 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 say, '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).
- Grains, originally used for weighing gold (based on a grain of wheat), today used for weighing powder for ammunition or catalysts

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).
CALIBRATION
Inaccurate readings can be fixed by calibrating the scale, this is something that is very easy for you to do yourself with the two 10g weights supplied. Giving inaccurate readings does not mean it is broken - all electronic measuring devices need calibrating every now and again, see .
