    • A tangent for a meter having a plurality of tangent members locked in adjusted position by a releasable locking means so that during normal operation the adjustment components thereof are not subject to strain, wear, or the action of the operational working forces. Upon release of the locking means the tangent can be adjusted for stroke and timing in the respective longitudinal and transverse directions by rotation of separate adjusting screws. Each of the adjusting screws is held captive in one of the adjacent tangent members and engages a threaded portion in the other of the adjacent tangent members, whereby rotation of said screw causes relative motion between the tangent members to move the same toward or away from each other.
    • 具有通过可释放的锁定装置锁定在调节位置的多个切线构件的仪表的切线,使得在正常操作期间,其调节部件不受应变,磨损或操作作用力的作用。 在释放锁定装置时,可以通过分开的调节螺钉的旋转在相应的纵向和横向方向上对切线进行行程和正时调节。 每个调节螺钉被固定在相邻的切线构件中的一个中,并与相邻的切线构件中的另一个中的螺纹部分接合,由此所述螺钉的旋转引起切线构件之间的相对运动,以使其相对于每个 其他。

    • A system and method for optimizing liquid-handling parameters for liquid-handling instruments based on automated use of Design of Experiments principles. An automated factor screening experiment generates a fractional factorial design, creates a set of liquid classes, directs a pipetting control program to execute a worklist of pipetting commands, and performs an effects analysis to determine the factors affecting pipetting precision. An automated response surface methodology experiment based on a central composite experimental design is used to determine the optimal level of factors affecting precision of pipetting. An automated range-finding experiment determines the useful volume range of the liquid class so developed. An automated accuracy calibration experiment generates a calibration coefficient for the liquid class. An automated liquid class verification experiment then evaluates the precision and accuracy of the liquid class.
    • 基于实验设计原理的自动化使用,优化液体处理仪器的液体处理参数的系统和方法。 自动化因子筛选实验产生分数因子设计,创建一组液体分类,指导移液控制程序执行移液指令的工作列表,并执行影响分析以确定影响移液精度的因素。 使用基于中心复合实验设计的自动响应面方法实验来确定影响移液精度的因素的最佳水平。 自动测距实验确定了如此开发的液体类的有用体积范围。 自动精度校准实验产生液体类的校准系数。 自动化液体类验证实验然后评估液体类的精度和精度。
