How long will spare parts be available for my new jewelry scale?
Spare parts for jewelry balances and scales are readily available at any time. If we stop production of a particular jewelry balance model, spare parts will be available for a further three years after the end of production.
What balance readability is recommended for weighing gold and for weighing silver?
For weighing gold, a jewelry balance with a readability of 0.01 g is recommended. For weighing silver, a readability of 0.1 g/1 g is recommended.
How can I clean my jewelry balance?
General dust and dirt on your jewelry balance can be wiped off with a damp cloth. More thorough cleaning is achieved through the use of isopropanol/ethanol (70%). Acetone is not recommended. For more information on balance cleaning, check out our balance cleaning guide.
What is the difference between carat in gold weighing and carat in diamond weighing?
In gold weighing, the number of carats, or karats (k), refers to the purity of the gold with 24 carat gold (24k) being the most pure. When weighing diamonds, carat is the weight unit. 1 ct is equivalent to 200 mg.
Which is the best kind of scale for weighing diamonds and other precious stones?
METTLER TOLEDO's carat balances and scales are ideal for weighing diamonds and gemstones as they offer higher readability that is suitable for weighing small items. The default weight unit is also conveniently set to carat.
How often do I need to recalibrate my jewelry scale?
You should check the performance of your jewelry scale regularly using a reference weight to see if it needs to be recalibrated. In addition, a jewelry balance or scale should always be recalibrated whenever it is moved to a new location.
What is the d value and what is the e value? What does it mean when we talk about e=d or e=10d?
d is the smallest division that a balance or scale can display.
e is the smallest interval on a balance or scale that can be used in a business transaction.
For example, a scale has d = 0.001 g, providing weight results to 3 decimal places. In the case that e=d, the scale can be used in business transactions measuring weight to 3 decimal places (0.001 g). In the case that e=10d, the balance can only be used in business transactions measuring weight to 10 x 0.001 g or 0.01 g.
My jewelry scales have a readability of 0.01 g. Does this mean I can weigh items as small as 0.01 g?
No. It is important not to confuse the readability of the scale with the minimum weight that can be weighed accurately on the scale. The minimum weight defines the weight of the smallest item you can weigh, while still meeting your desired accuracy requirements. The minimum weight of your jewelry scale is determined at the time of installation and is checked every time the scale is recalibrated. In the following document, you can find the typical minimum weight values that you can expect for each jewelry scale.
How can I find out if I need a Legal for Trade jewelry scale or a regular jewelry scale?
Legal requirements for weighing equipment vary from country to country. Therefore, it is important to check the local requirements of the area in which you do business.
What is the difference between a jewelry balance and a laboratory balance?
Jewelry balances have a special software to meet the needs of the jewelry industry. For example, they have special weighing units.
Is a Legal for Trade jewelry scale more accurate than a regular jewelry scale?
No, all of our jewelry scales have the same METTLER TOLEDO quality and accuracy. Legal for Trade scales undergo additional testing and a tamper-proof seal is added during the manufacturing process.
