Technical

RESOLUTION / CAPACITY: 100g / 0.01g

Also switchable to the following: 

- grams, metric. Today everyone weighs gold in grams. But some UK dealers still like the answer in ounces (Troy ounces).

- Ounce Troy, for weighing precious metals (the same ounce that was once used for weighing mail, not the same ounce used for weighing food)

- ounce (some say, 'English' ounce, correct term is 'Avoirdupois' ounce) for food

- carat (ct) for gemstones and diamonds, not to be confused with carat as gold purity).

- grains (gn), originally used for weighing gold (based on a grain of wheat), today used for weighing powder for ammunition or catalysts for adhesives

Guarantee

This scale is guaranteed for 1 year

The guarantee is invalid if there is:

- obvious damage, e.g. dents, holes, cracked casing, weighing platform loose.

- signs of 'foreign material'. That's anything that should not be there, e.g. residues of herbs, chemicals, spilt tea, corrosion from leaking batteries.

CALIBRATION

Inaccurate readings can usually be fixed by calibrating the scale, this is something you can do yourself if you have a calibration weight. THIS IS NOT A FAULT, all electronic measuring devices need calibrating every now and again, see calibrating weighing machines. The weight required for this balance is 50g.
