WeighingAnalytical balancesIt is a high-precision measuring tool used to measure the mass of a substance. Correctly taking the readings of your balance is one of the keys to ensuring accurate measurements. Here are some ways to analyze your balance readings:1Level Adjustment: Before taking an analytical balance reading, the balance must be placed on the surface of the water platform and the base knob of the balance must be adjusted so that the balance beam is horizontally balanced. If the hands of the balance are tilted to one side, the base of the balance needs to be adjusted so that the beams are balanced.
2.Preheating: It should be warmed up for a certain amount of time before use to ensure that its electronic components are working properly. It is normal for the balance to be constantly changing during warm-up.
3.Zeroing: Before taking a balance reading, the hands of the balance need to be reset to zero. Typically, this can be achieved by pressing the zero button or adjusting the weights.
4.Weighting: When measuring the mass of a substance, you need to place a precise weight on the balance and then adjust the position of the yard so that the pointer of the balance points to the desired reading. The mass of the weight plus the mass indicated by the code is the mass of the substance.
5.Take the reading: After adding the weight, observe whether the pointer of the balance is stable, and when the pointer is stable, take the reading of the balance. Keep your line of sight perpendicular to the pointer when reading to avoid errors due to parallax.
6.Recording data: After taking the readings of the balance, they should be recorded in time for subsequent data processing and calculations. When recording data, information such as measurement time, measurement personnel, measurement environment, etc., should be included for traceability and verification.
7.Precautions: When using the balance, care should be taken to avoid the influence of vibration, magnetic field interference and other factors on the measurement results. At the same time, it should be operated and maintained in accordance with the requirements of the manual to ensure the normal operation and service life of the balance.
In conclusion, taking the balance reading correctly is one of the keys to ensuring the accuracy of the measurement. When using a balance, follow steps such as level adjustment, preheating, zeroing, weighting, reading and data recording, and take care to avoid errors and interferences. At the same time, it should be operated and maintained in accordance with the requirements of the manual to ensure the normal operation and service life of the analytical balance.
