The TOP mistakes that most Jewelry Scale Buyers MakeAs you may know, determine the size and value of various gems stones and precious metals requires the use of a precision digital scale.
Unfortunately - the biggest mistake that most precision scale buyers make is they simply do NOT know which digital scale features they need for their application. In order to make your precision scale selection FAST & Successful, we have provided you with the following "Precision Scale Checklist". Simply use this check list to determine which scale features you need for your special application. 1) Design
WEIGHING UNITS (g, ozt, ct, grains, dwt, oz) In addition, if you are looking to weigh in MILLIGRAMS - mg, you will find most scale only display in grams and 0.001g = 1mg or 0.01g = 10mg. You will also see the term TCW, which means "Total Carat Weight". The term TCW refers to the TOTAL weight of ALL stones in one (1) piece of jewelry or pair of earrings. Before you select your precision scale, make sure that it has the weighing units you need for your special application. In addition, make sure it meets your capacity and accuracy needs.
CAPACITY vs. ACCURACY
As you may have discovered, there is generally a direct relation between capacity and accuracy. The higher the accuracy of a scale, the scale will generally have a lower capacity. If you are looking for a digital scale with a high capacity and a high accuracy, this will most likely be very expensive. Due to the lower prices, most gem stone collectors use a CARAT scale with an accuracy of 0.05ct (0.01g) and a capacity of 250ct or 500ct (50g or 100g). However, most professional dealers or collectors will use a CARAT scale with an accuracy of 0.01ct (0.001g) and capacities from 250ct to 1500ct (50g to 300g). Once you have determined this information, you will simply need to select a precision scale that meets your capacity and accuracy requirements.
Will you be carrying your precision scale to different locations or will it stay at one location? Of course, if you need to bring your scale with you to various locations, then you should select a scale that is compact & portable (i.e. pocket scale or mini scale). However, if you are placing your scale on a bench/table, then you may want to select a different sized precision scale. In addition - your precision scale's platform size will be directly related to its portability and should also be based on the size of the items to be weighed. However, as you will read in the next section - you may be able to increase the size your precision scale's platform by using the Tare Feature. TARE FEATURE Platform Example: If you need to weigh an item that will not stay on your precision scale's platform, you may be able to increase the platform size by placing a flat item - such as a plastic plate - that is larger than the platform and pushing the TARE button. This will remove the weight of the plate and you will now have a larger weighing platform. Container Example: Place your container (i.e. bowl, cup, etc.) on the scale's platform that will hold the item(s), and then push the TARE button. Your scale's display will reset to 0 by subtracting the weight of the container. Then simply place the item(s) in the container and your scale will display the actual weight of the item(s) in the container. In addition - if you need to weight more items in the same container, you can simply keep pressing the Tare button to reset the scale's display to zero and then add the next item.
If the precision scale you select offers an optional calibration weight, we highly recommend that you purchase this accessory to keep your precision scale accurate. BATTERY and/or 110V POWER In addition, since precision digital scales only use a small amount of power and most units have auto shut off, the batteries will keep going and going and going. MANUFACTURERS' WARRANTY SPECIAL NOTICE: We highly recommend you AVOID any scale manufacturer that offers a so-called "lifetime warranty". We have discovered that most of these companies require a substantial fee for processing your warranty claims. As you know, common sense says "If it sounds too good to be true - it probably is". In addition, you should always use extreme care while operating or transporting your scale. Dropping your precision scale will most likely render it useless or cause enough damage to affect its accuracy. This type of damage will also void most manufacturers' warranties.
