Electronic Balance measurement result error analysis and calibrating method

Electronic Balances, also known as balances, are widely used in laboratories and scientific research fields due to their advantages such as convenient and fast operation and accurate reading. Also, errors may occur during use. In order to ensure the reliability of the measurement results, this paper will research and analyze the influencing factors that cause errors in the balance measurement results, and propose relevant solutions to reduce the occurrence of measurement errors. Now take the electromagnetic electronic balance as an example for analysis and introduction. As a very important measuring instrument, electronic balance has been widely used in production, scientific research, trade and other fields, as well as in daily life. However, as a measuring instrument, its measuring performance will deviate more or less from the original design index after being used for a period of time, so it is very necessary to carry out regular verification of its measuring performance. The main technical basis for the current verification is JJG 98-90 Trial Verification Regulations for Non-automatic Balances. However, under the conditions stipulated in the regulations, the test results of different Testers may still be different. Combining my many years of work experience, I will make some analysis here for reference.
