Electronic analytical balances are highly sophisticated laboratory instruments, so be careful when using them, and pay more attention to maintenance methods:
1. Do not subject it to vibration or dropping; electronic balances should not be placed in an over-cooled and overheated environment. They should be placed in a room with a constant room temperature. Before the electronic balance is used, it should be suitable for a minimum of 1 hour in the new environment. .
2. When the electronic analytical balance is connected to the power source, it must be warmed up for half an hour to an hour according to the requirements of the instructions. The laboratory electronic balance should not be frequently cut off during normal use. Weighing should not exceed the maximum weighing capacity. The +2%, but Mettler electronic balance has a very good performance in terms of weighing overload, Mettler ME series of electronic balance overload protection up to 100KG, the balance of the brand of his brand can not reach the anti-meter scale electronic defense Overload performance requires weighing in the range to avoid damage to the sensor.
3, In addition, before the use of electronic analytical balance, it is best to use the weight after the start of the weighing several times, so that the internal components of the electronic balance fully warmed and then officially weighed, the weighing results obtained will be more accurate.
4. The electronic analytical balance should not be moved as often as possible, and should be handled with care. When weighing, gently place the item on the weighing pan to avoid inaccurate weighing or damage to the internal parts of the scale. Windshields, because the use of electronic analytical balances is required to be used on stable, wind-free surfaces.
It is best to establish a standard operating procedure for the use, maintenance, and cleaning of electronic analytical balances in the laboratory to standardize the use of electronic analytical balances and to extend the useful life of electronic balances.
