  • Page 15: Vertical Rotation

    Operation Scanning Mode In scan mode, the laser rotates slowly, "searching" for the Magnetic Scanning Target. When the target is properly placed in the beam path, the laser beam will scan rapidly back and forth on the target and "track" the target as it is moved in its path. To change to scanning mode when operating, press the Mode Control Pad (see page 10).

  • Page 16: Continuous Scan

    Continuous scan (Scan line length can be "Drawn" and held for "Hands-free" operation) Place target in beam path and hold for a moment. The scanning beam will hesitate, then start again. When the target is now removed the beam will continue to scan automatically. To change the length of the scanning line, move the target left or right after the initial scan hesitation and the scanning line length will increase until the target is removed.

  • Page 17: Laser Sensor Mode

    For long range or outdoor applications, the instrument can be used with an optional elec- tronic laser sensor. The Topcon LS-70G model is recommended. Press the Mode Control Pad to select Laser sensor mode. The beam rotates at 300 rpm in this setting.

  • Page 18: How To Remove/Install

  • Page 20 How to Install Insert the head protector pin into the groove of the instrument until you feel it click. Pin, Groove Bring down the head protector until you hear a clicking sound. Check that the head protector is securely locked.

  • Page 21: Height Alert Function

    Height Alert function When auto-leveling and height alert function are active, this function prevents the instru- ment from operating if it is disturbed (after the laser beam emits for one minute). This helps insures accurate control. If the height or inclination of the instrument changes, the height of instrument should be verified and re-established if necessary.

  • Page 22: Setting Slopes

    Setting Slopes The laser beam can be manually sloped in either the X or Y axis (single slope) or both axes (compound slope). With the inclination of the instrument as the standard, laser beam can be sloped within the range of ±5° up or down. •...
