    Basic Operation Set the RL-H1Sa on a tripod or flat surface. (See "Instrument Set-up Procedure " on page 12.) Turn the instrument ON and enter a grade if Ｘ  ％  ｒｐｍ  １００  ×  ＥＮＴ  ＯＮ  ＰＯＷＥＲ  ＭＡＮＵ  desired. (See "Entering Grade " on page 18.) Set beam rotation to the desired speed.

  • Page 14: Preparation And Functions

    For battery installation instructions, see "Maintaining Power Sources " on page 21. Instrument Set-up Procedure Set the instrument on any smooth surface that is within ±5° of true level. The RL-H1Sa auto-level system will not function if the unit is placed more that 5° out of level. For best operation, it is recommended that it be mounted to a tripod.

  • Page 15: Battery Warning Indicator

    Battery Warning Indicator The Battery warning indicator indicates the battery power remaining. Battery is sufficient. The power is low, but laser is still usable. In this state, the laser will transmit the battery warning signal to laser sensor. AC/DC converter AD-9B or AD-7C is available for continuing the operation. Dead batteries.

  • Page 16: Auto-Leveling Lamp

    Auto-leveling lamp Flashing : Auto-leveling is in process. When automatic leveling is almost complete, the flashing rate will be slow. The head will not rotate and the laser beam will not emit during the auto-leveling process. ON Solid: Auto-leveling is complete. The rotary head is active and emits the laser beam.

  • Page 17: Inclination Warning

    Inclination Warning If the instrument is positioned outside of the auto-leveling range (±5°), the Auto-leveling lamp will blink and the grade display will disappear. Blinking...

  • Page 18: Height Alert Function

    Height Alert function When auto-leveling and height alert function re active, this function prevents the instrument from operating if it is disturbed. This insures accurate control. If the unit is disturbed, all dis- plays and Auto-leveling lamp will flash. The elevation (height of instrument) should be verified and re-established if necessary.

  • Page 19: Aligning Direction Of Grade

    Aligning Direction of Grade When using the laser with a percent of grade entered, the laser must be properly aligned so the slope of the laser beam is parallel to the desired direction of grade. The sighting collimator on top of the instrument is cali- brated to the grade axis of the laser beam.

  • Page 20: Entering Grade

    Entering Grade The laser beam can be sloped in the X axis (single slope). X-axis grade range: -5.000% to +10.000% Single Axis Plus (+) Minus (-) - 5% +10% X axis X axis +10% Horizontal - 5% Ｘ  Minus (-) ％ ...

    How to enter grade Setting example: Grade toward X-axis -2.8% Operating procedure Operation Display Turn the instrument on by pressing the power con- Power ON trol pad. Auto-leveling will start. Press the [ X] key to activate grade entry. The position of the second figure to the left of the decimal point will blink.

  • Page 22: Masking (Laser Beam Shutter)

    Masking (Laser beam shutter) The RL-H1Sa features electronic beam “masking” to prevent the beam from transmitting on one or multiple sides of the instrument. This can be useful to eliminate duplicate laser beams on job sites where more than one laser may be in use.
