Set linear compensation Brief Introduction Coordinate System DRO is an instrument which can measure position of work piece when processing. Coordinate system must be definite first for more efficiency and accuracy. In horizontal plane, the X axis is parallel with the operator; Y axis is perpendicular to X axis. Z-axis is perpendicular to horizontal plane. Positive direction of axis is set as the figure. It also can be changed as customer. The value of one point position is the distance relative to the origin of coordinate. For a work-piece as Figure A, the value of each point position is as the Figure B when point O is the origin of coordinate Description of Key Function Interface A: Linear Scale InterfaceB: RS232 Interface BASIC OPERATION Power on Function: Power on then DRO enter normal display state. It can memorize the following parameter after power . A. The scale position where power off; B. ABS/INC/SDM mode, C. Metric/Imperial mode, NOTE: When the power switclt is turned on, press and hold the key "ENT" to entre the internal settings. If a linear scale is used for segment compensation, the system will prompt to find the "RI" point. If the linear scale is not moved after Power off, press the key "CA" to exit without find "RI" point. Zeroing Function: Zero the designated axis in normal display state. Zeroing is used to set the current point as datum point NOTE: When zero in ABS coordinate has no effect on INC disaplay value. Zeroing in INC coordinate has no effect on ABS and SDM display value.Press the zero key of the same axis will cancel above zero operation if the scale kept still after zero. Preset Data to designed axis Fuction: Preset a value to current pos山on for a designed axis in normal display state Example: Machine the work-piece from the A to B. Steps: 1. Move the machine table, and align the lathe tool to A2. Press X-1-0-ENT, which means the preset data is "10"3. Moving the machine table until "27.000" is displayed in X window. Now it it the position of B. Toggle display unit between mm and inch Function: Length can be displayed either in "mm" (metric) or "inch" (imperial) . Display unit can be toggled between mm and inch Example: Display value toggle from mm to inch STEPS: 1. DRO returns normal display state. Press INC, the display unit is inch now. NOTE: It is invalid to toggle between mm and inch while axis is encoder. Mid-Point Calculation Function: Set the center of work piece as datum by halving the displayed value. Example: Set the center of rectangle as datum as the right figure. Absolut / Incremental / 500 groups SDM Function: DRO has 3 display modes: the absolute mode (ABS), the incremental mode (INC) and 500 groups Second Date Memory (SDM) with the range of 001 to 500. Zero point of work-piece is set at the origin point of ABS coordinate.The relative distance between datum of ABS and SDM remains unchanged when ABS datum is changed.In ABS coordinate. The coordinate value is black; In INC coordinate. The coordinate value is blue; In SDM coordinate. The coordinate value is red. Clear ALL SDM Datum Function: Clear the Datum of all SDM 1-500. After clearing, the display value in SDM coordinate is equal to the value in ABS coordinate, Lathe Function If two scales are installed in one axis, the position of the work-piece should be the sum of these two values in this direction. It is called lathe function.

⚖LCD digital readouts can help improve the accuracy and precision of machining operations by providing a precise measurement of the position of the cutting tool. This can help to ensure that the tool is positioned correctly and that the desired results are achieved.

⚖The grating digital display body is made of high-quality Aluminum alloy which has high reliability and durability, and scratch resistance.

⚖Applicable for milling machine, drilling machine, grinding machine, lathes, profile projector, video measuring machine, position monitoring, coordinate measurement, working table monitor, mechanical control as well as other area of linear scale and rotary encoder.

⚖The digital display can be connected to 10 kinds of resolution scale, 0.05μm, 0.1μm, 0.2μm, 0.5μm, 1μm, 2μm, 5μm, 10μm, 20μm, 50μm and so on 10 kinds. After installing the scale, if the resolution is different from the current value, the scale must be set in the digital display. If the resolution is different from the current value after installing the scale, the resolution of the scale must be set in the digital display, otherwise the reading will not be correct.
