INTRODUCTION This chapter describes the Laser Scan Micrometer (LSM) models and 1 nomenclature of the Display unit and the Measuring unit. 1.1 Outline This system is an accurate, non-contact measurement system capable of measuring workpiece dimensions at a high speed using a highly directional scanning laser beam. This non-contact optical measuring system is capable of measuring workpieces which are difficult to measure with conventional measuring instruments. It performs simple and accurate meas

SETUP This chapter describes the connection between the Display Unit and 2 Measuring Unit. 2.1 Unpacking and Acceptance Check Your LSM has been thoroughly inspected prior to shipment. The mechanical, electrical, and optical systems are guaranteed to operate properly. Unpack the package and check that the accessories, for the Display Unit or Measuring Unit, and signal cables, etc., are intact and not damaged. Contact Mitutoyo if anything is damaged or missing. 2.2 Connecting the Cables Make sure

Step 2: Attaching the ID unit 1.Loosen the two screws that secure the ID unit protection cover at the left on the real panel of the Display Unit and remove the cover by sliding it rightward. 2.Remove the dummy ID unit (amber) that has been mounted at the left of the “TRANSMITTER-1” connector on the rear panel of the Display Unit, then insert the ID unit (beige) that comes in the same package as the Measuring Unit. This ID unit stores critical data that ensures the accuracy of the Measuring Unit

2. SETUP IMPORTANT • If the dummy ID unit is still mounted, “ ” PROG is displayed in the lower section of the display. If this is the case, turn off the power and replace the dummy ID unit with a proper ID unit. • If the ID unit is not installed or if the serial number of PROG the Measuring Unit is not consistent with that on the ID unit, the system will not work and an error code as shown at the right will be displayed at power on. At the same time, the 6-digit serial number of the measuring un

Step 5: Checking the remote interlock connector Make sure that the short-circuiting pin is inserted into the “REMOTE INTERLOCK” connector on the rear panel of the Display Unit. If this short-circuiting pin is not inserted, laser emission is disabled, even if the power switch is on. To emergency stop laser emission, refer to the following diagram. Switch ON: Laser emission ON Switch OFF: Laser emission OFF Short-circuiting pin Switch Applicable connector: PJ-2 5V, 3mA (Manufacturer: Sato Parts) S

2. SETUP 2.3 Preliminary Checks The necessary connections should be completed by following the procedure described in the previous chapter. Simplified operation checks are described here. Step 1: Fully open the lens cap and shutter of the Measuring Unit. Fully open the lens caps and beam shutters of both the emission unit and reception unit to ready the laser beam for emission. The lens caps should be completely removed, and the shutters should be as shown in the diagram below. Emission window S

• An error may be displayed at this stage, PROG however, the display at the right is not actually an error. Check the shutter of the Measuring Unit. For information about other errors that may result refer to Section 7.3, “Error Messages and Remedies”. 2.4 Initializing the LSM-6900 Display Unit After making sure that this unit is operating normally, initialize the Display Unit so it can recognize the Measuring Unit(s) to be used. Initialization of the Display Unit is also required if the Measuri
