Jewelry digital scales commonly used for counting scales weighing scales counting accuracy is determined by the accuracy of the sampling and calculation of the single weight, so the counting scales, weighing scales, the choice and operation should pay attention to the following matters:
1, choose the appropriate weighing accuracy:
According to the counted items of the single large and small selection of weighing accuracy of the scale, jewelry digital scale repair, in principle, requires that the scale should be smaller than the single weight of the graduation value, such as the single weight of the items for the 7g, you should choose the graduation value of less than 5g of the counting scale. Of course, suppose you only have a scale with a graduation value greater than a single weight. In that case, you can combine several items into a counting unit in the form of counting, but it will also affect the counting accuracy.
2, can not exceed the max capacity of jewelry scales
Jewelry digital scale market research mentioned that the jewelry digital scale counting is not allowed to sample weight should be greater than the scale’s smallest weighing capacity ( smallest weighing capacity = largest weighing capacity ÷ 150, for example, the smallest weighing capacity of the 3kg scale is 3kg ÷ 150 = 20g, then the weight of the sampling should be greater than 20g).
3. Test as many samples as you can
Jewelry digital scale maintenance, incorrect and other common problems detection methods
1, placed flat
Please place the jewelry digital scale on a stable and flat desktop or the ground; do not place it on a vibrating and unstable desktop or pedestal.
2, placed in a stable environment
Avoid placing it where the temperature changes too much, or the air flows violently, such as direct sunlight or cold air vents.
3、Use an independent power outlet to avoid interference from other electrical appliances.
4、Adjust the level to the center
Adjust the adjusting foot of the jewelry digital scale so that the scale is stable and the bubble in the level meter is in a circle*.
5、Warm up before use
Please do not place objects on the scale when the power is turned on. Warm up the machine for more than 15 minutes before use (high-precision scales must take longer).
Jewelry digital scale use precautions:
1. It is strictly prohibited to rain or water rinse if accidentally stained with water with a dry cloth to wipe clean; when the machine does not function properly, it should be sent to repair as soon as possible.
2, knocking, impact, and heavy pressure are strictly prohibited.
3, do not put in high temperature and humid environments places (except waterproof anti-corrosion scale).
4, do not let cockroaches or small creatures invade the machine so as not to cause damage.
5, jewelry digital scale maintenance: jewelry digital scale if not used for a long time to wipe the machine clean into the desiccant wrapped in a plastic bag, there is the use of dry batteries should be removed, and rechargeable batteries should be charged every three months to ensure that the service life.
