Chapter 1 Getting Started Outline and Features of LS-7600 Series The LS-7600 Series is a high-speed, high-accuracy digital micrometer used for the dimensional measurement of objects without coming into contact with the objects. It is such a versatile model that it has a wide range of applications including in-line measurement and offline measurement.
Chapter 1 Getting Started ■ Principle of Measurement The high-intensity GaN green LED radiates light, which will be changed into uniform parallel light through the special diffusion unit and collimator lens and emitted to the target in the measuring range. Then the shadow image of the target will appear on the HL-CCD (high-speed linear CCD) through the telecentric optical system.
Chapter 1 Getting Started System Applications The LS-7600 Series has a wide range of applications when used in combination with commercially available peripheral devices. 1 PC Control values or measuring values are retrieved over RS232C. Indicator Light and Buzzer Alarms are generated according to the output of discrimination results. LS-7601 Photoelectric Sensor or Proximity Sensor Timing input signals are sent whenever targets are detected.
Chapter 1 Getting Started Package Contents Check that nothing is missing from the LS-7600 Series package before use.
