教你如何选择电子天平？选择电子天平应该从电子天平的绝对精度(分度值e)上去考虑是否符合称量的精度要求。如选0.1mg精度的天平或0.01mg精度的天平，切忌不可笼统地说要万分之一或十万分之一精度的天平，因为国外有些厂家是用相对精度来衡量天平的，否则买来的天平无法满足用户的需要。例如在实际工作中遇到这样一个情况，用一台实际标尺分度值d为1mg，检定标尺分度值e为10mg,最大称量为200g的Mettler电子天平，用来称量7mg的物体，这样是不能得出准确结果的:在《JJG98-90非自动天平试行检定规程》中规定，最大允许误差与检定标尺分度值“e”为同一数量级，此台天平的最大允许误差为1e，显然不能称量7mg的物体;称量15mg的物体用此类天平也不是最佳选择，因为其测试结果的相对误差会很大，应选择更高一级的天平，有的厂家在出厂时已规定了最小称量的数值。因此我们在选购及使用电子天平时必须考虑精度等级。（2）对称量范围的要求：选择电子天平除了看其精度，还应看最大称量是否满足量程的需要。通常取最大载荷加少许保险系数即可，也就是常用载荷再放宽一些即可，不是越大越好。
Teach you how to choose the electronic balance? Choice of electronic balance should be from the absolute accuracy of electronic balance ( index value E ) to consider whether it meets the weighing accuracy. Such as the selection of 0.1mg precision balance or 0.01mg precision balance, should not generally be 1/10000 or 1/100000 accuracy of balance, because some foreign manufacturers is to use relative precision to measure the balance, or to buy the balance can not meet the needs of users. For example, in practical work, encountered such a situation, a practical scale division value D for 1mg, e for 10mg verification scale division value for 200g Mettler, the largest weighing electronic balance for weighing, 7Mg objects, this is not an accurate result: in the" JJG98 90 verification regulation of non - automatic balance" in regulation, maximum permissible error and calibration scale division value" e" for the same order of magnitude, the balance of the maximum permissible error of 1E, apparently not weighing weighing 15mg 7Mg objects; objects with such balance is not the best choice, because of its test results in relative error will be very big, should choose higher the level of the scale, some manufacturers in the factory has been set the minimum value. Therefore, we in the purchase and use of electronic day usually must consider the precision grade. ( 2) on the weighing range requirements : the choice of electronic balance in addition to its precision, also should see whether meet the needs of the largest weighing range. Usually takes the maximum load plus a little insurance coefficients, which is commonly used to relax some load can be, the better not.
维护与保养
Maintenance and repair
1、将天平置于稳定的工作台上避免振动、气流及阳光照射 电子天平。
In 1, the balance placed in a stable working platform to avoid the vibration of air and sunlight, electronic balance.
2、在使用前调整水平仪气泡至中间位置。
In 2, before use to adjust the level bubble to the middle.
3、 电子天平应按说明书的要求进行预热。
In 3, the electronic balance should be according to the requirement of preheating.
4、称量易挥发和具有腐蚀性的物品时，要盛放在密闭的容器中，以免腐蚀和损坏电子天平。
4, weighing volatile and corrosive materials, be in full bloom in a closed container, so as to avoid the corrosion and damage to electronic balance.
5、经常对电子天平进行自校或定期外校，保证其处于最佳状态。
5, often on the electronic balance from the school or outside the school on a regular basis, ensure that it is in the best condition.
6、如果电子天平出现故障应及时检修，不可带“病”工作。
6, if the failure of electronic balance should be repaired in time, not with "sick".
7、操作天平不可过载使用以免损坏天平。
In 7, operating balance can not be used so as not to damage the balance overload.
8、若长期不用电子天平时应暂时收藏为好。
8, if the long-term use of electronic day usually should be temporarily for good.
