带有内置传感器的螺丝刀具有+/- 1%的刻度范围的螺丝驱动扭矩精度(例如,80 Nm螺丝刀的精度为+/- 0.8 Nm);扭矩精度与所要求的最大扭矩无关。换能器版本在螺杆驱动刚性紧固件时的重复性精度为1%,无换能器版本为3%。为了获得最好的效果,应该使用合适的夹紧系统来固定螺丝驱动单元。ACE螺杆驱动单元有单个螺杆驱动主轴和每个主轴的控制单元。-半图形LCD显示,4行,每行20个字符。内置的薄膜键盘。最多5个螺杆驱动程序,每步可设置,存储和调用从键盘。每个程序步骤可由用户根据需要进行编程,取值如下:i.转速/旋转方向ii.旋转方向要达到的扭矩或角度。 Time limit or degree limit range within which the set torque/angle must be reached. - Up to 1024 screw driving operations can be stored to memory. - Torque curve of the last screw driving (resolution 0.01 seconds) can be stored to memory. - RS-232 C connection to PC for reading screw driving data on-line - RS-232 C connection to PC for transferring memory data.
