Summary

Pocket size balance for gemstones.

Weighs up to 100g and down to 0.01g. Suitable for weighing gold up to 100g (though it's a bit 'over the top' in sensitivity for just gold); good for gemstones (100 points = 1 carat, 5 carat = 1 gram...so this weighs down to the nearest 5 points).

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

10 years. 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 a xxg weight (not supplied).  Giving inaccurate readings does not mean it is broken - all electronic measuring devices need calibrating every now and again, see calibrating weighing machines. 

 After 1 year proof of purchase required and £6.50 return postage payable.
