线性 表示系统的实际输出和理论直线的一致程度。如图所示，当
产生线性误差时，系统在空载和满载时的输出是正确的，但这两点 之间的输入－输出点和理想状态不一致。线性误差就是理论直线和 实际输出曲线之间的最大差值。

潮湿、腐蚀性物质或碎屑的影响
潮湿或腐蚀性物质会损坏传感器， 缩短其使用寿命。 电缆和接线盒也应有防潮保护措施 。 传感器和容器上粘有粉尘或碎屑会 产生回零误差，影响称量精确度。 使用MTCN的不锈钢称重模块可以抵 御潮湿或腐蚀性物质的侵蚀。 传感器和容器应定期清洁。

温度影响
温度的变化会使容器收缩或膨胀， 这将产生侧向力加载于传感器上从 而影响称量的精确度。 如果温度超出传感器的使用范围， 会损坏传感器的应变片。 在传感器和容器之间加绝缘和隔热 材料可以消除温度变化产生的影响 。

安装底座本身应有足够的强度和刚性，一般要求高于传感器本身的强度和刚度。
2、称重传感器要轻拿轻放，尤其是由合金铝制作弹性体的小容量传感器，任何冲击、跌落，对其计量性能均可能造成极大损害。
对于大容量的称重传感器，一般来说，它具有较大的自重，故而要求在搬运、安装时，尽可能使用适当的起吊设备（如手拉葫芦、电动葫芦等）。

梅特勒-托利多天平使用说明书
To ensure the future success of late -stage product development processes, itcontinuously strengthens its capabilities, and seeks to maximize the time it spendson the science through investment in emerging and state -of -the -art technologiesthat can reduce otherwise trivial manual labor. This mindset drove the productdevelopment team ’s search for an automated solutions preparation system that iscompliant with regulatory requirements in a GMP setting. For example, for themeasuring devices in the system the team needed to follow the requirementsstated in pharmacopeias (USP and Ph.Eur.). They recognized that the balances, pHprobes, conductivity probes, temperature sensors and volumetric glassware mustmeet the stringent requirements set by these pharmacopeias. In addition, it wasalso essential to comply with data integrity requirements set by the FDA ’s 21 CFRPart 11 and EU ’s Annex 11. The selected system needed to capture and log criticalaspects of record keeping such as audit trails, reports, recipe composition, userpermissions and dosing records.THE CHALLENGEA top 20 global pharmaceutical company with headquarters in Europe, has been inoperation for a century. With a mission of developing medicines and treatmentsfor endocrine diseases, this company helps people live better every day. In orderto speed the development of medicines and treatments to market, it has adopteda culture of innovation where implementing cutting edge technology isencouraged, embraced and expected. It was this innovation culture that spurredthe concept of moving a research automation system into the GMP environmentand improve the efficiency of laboratory personnel and operations there.ABOUT OUR CUSTOMER"The flexibility the solution has provided for just -in -time preparation is a major benefit."AUTOMATED PREPARATION OFREAGENT SOLUTIONS FOR GMP LABS Case StudyAT A GLANCEC. SchwartzProject ManagerLabMinds collaborated with aTop 20 Global Pharmaceutical company and madeenhancements to Revo thatevolved the research productinto a GMP compliant solution.C. Schwartz, Project ManagerTHE SOLUTIONAfter an extensive review of available solutions,they selected LabMinds® Revo®,the benchtop automated solution preparation system that enables companies to automate the reagent preparation bMinds,upon the customer’s request,decided to collaborate and make enhancements to Revo that would evolve the research product into a GMP compliant solution.The project was launched in May of2019and they set out to find a dedicated and innovative technical Project Manager to drive this project.Schwartz was assigned as Project Manager.Schwartz is a specialist in laboratory automation and has a strong track record of leading teams and driving transformation.He accepted the challenge in a large part due to the fact that he had previous exposure to the Revo system from the2016SLAS conference when Revo won the innovation award.He recognized the potential to transform Revo into a GMP compliant system and accepted the challenge.REAGENT SUPPLY SCENARIOSThe above graphic demonstrates the need and the options available for reagents in a lab.By using the Revo, just in time reagent solutions are achieved without using lab personnel time.FORMING A TEAMSchwartz formed a dedicated team comprised of subject matter experts including a chemistry specialist and cross functional experts from other departments.This team combined forces with LabMinds and worked to deliver an automated solution preparation system that complied with GMP requirements.They knew that it needed to deliver a solution that provided the consistent quality,traceability and documentation required in the regulated pharmaceutical industry.The team also sought to solve three main challenges: reducing the time lab technicians spent on preparing reagents to allow them to focus on the science; limiting solution overproduction; and eliminating risk associated with manual documentation processes.After 18 months of intense dedication, the team achieved a huge milestone and Revo was approved internally for use in its GMP laboratory. The system approval was earned through a series of rigorous data integrity process reviews and hardware upgrades. They were then able to tackle the challenges they set out to solve. Just a few months after the launch, the team on -boarded many of its recipes and is already seeing positive impact.SYSTEM APPROVAL“I appreciate the opportunity to work for a company that iswilling to implement cutting edge technology. We willreap many benefits moving forward,” commentedSchwartz, the Project Manager. “The flexibility the solutionhas provided for just -in -time preparation is a majorbenefit. We have already reduced solution overproduction costs and leveraged the Revo system toreallocate our reagent prep team from redundant tasks towork that helps increase the speed of productdevelopment.”"I appreciate the opportunity to work for a company that is willing to implement cutting edge technology that will reap many benefits moving forward."C. Schwartz Project ManagerPrior to the implementation of GMP Revo, three laboratory technicians spent an entire daypreparing reagents for the week. Upon review of recipes required, many were found tohave an organic component. To overcome a current system limitation, LabMindsdeveloped a workflow process where the Revo produces the aqueous portion of thesolution with instructions for the organic component addition printed on the label. Eventhough organic components are still added manually it was decided that the newfoundflexibility of automating the manual weighing, pH verification and data registration madethe process worthwhile. The system now allows the team to order the reagents via theWeb or mobile interface, and reduces the FTE time needed to fulfill monotonous,procedural laboratory tasks by 66%. This allows these key team members to focus on thedata analysis and scientific work needed to produce results from sample analysis.POSITIVE RESULTSThis lab technician team also used to ensure that they did not run out of reagents during the week by creating an extra supply. At expiry, extra solutions were thrown away. Now the team has implemented just -in -time inventory best practices and produce the exact quantities of the solutions they need. They know that they have increased flexibility, and if they need more solutions they do not have to stop analysis to create them. They can simply reorder via the easy Web interface, and the solution will be ready within an hour. This flexibility allows the team to reduce the amount of inventory needed each week.Prior to the implementation, the team manually tracked preparation data on paper to ensure they could obtain the necessary information for upcoming audits. Now, the team utilizes a QR code printed on the bottle label that contains all information describing the preparation and scans this data directly into the LIMS system where a record is created for each bottle.C. Schwartz and the Revo systemhttps:///labmindsinchttps:///labmindsinchttps:///company/labminds/“After 6 months in operation I get continued feedback from the users on how happy they are to be relieved from the tight planning of manual preparation they used to have. Even though organic components are still added manually it is by far overshadowed by the newfound flexibility in the fact that all manual weighing, pH verification and data registration are completely removed from the process.”C.

This process not onlyreduces the chance of human error, but also frees up time for the labtechnicians to focus on other tasks.
