4. PREPARATION

*1 Always replace both batteries at the same time.Do not mix old and new batteries.

*2 Use alkali batteries. (Batteries for operation check are included in the package.) It is possible to use nickel cadmium or nickel hydride batteries; however, service life will differ.

*3 Generally, battery performance will weaken at low temperature. However, this is only temporary and the performance will recover when the temperature rises to the normal operational range.

4.1 Installing Batteries

1 Push down the section of the battery cover specified in the diagram at the left.

2 Open the cover.

3 Remove the cover.

4 Install batteries.*1), *2), *3)

5 Close the battery cover. Push the battery cover until you hear a click.

12

4. PREPARATION

1 Set up the tripod.Spread the tripod legs about the same distance apart so that the tripod head is approximately level. Tread the tripod shoes firmly into the ground.

2 Mount the instrument on the tripod.Hold the instrument on the tripod head and tighten the centering screw.

3 Level the instrument.

The compensator's operational range is ±12' however, an error message will not be displayed when the range is exceeded. Please make sure that the leveling operation is performed accurately.

At a correctly adjusted level, horizontal level is maintained by the automatic correction mechanism provided that the bubble is within the circle.

4.2 Setting Up the Instrument

Spherical head tripod:Loosen the centering screw and slide the instrument across the tripod head until the bubble is centered in the circular level. Tighten the centering screw.

Flat head tripod: Extend or push in the tripod legs until the bubble is centered in the circular level. When the bubble is more or less centered, turn the leveling foot screws until the bubble is exactly centered in the circle.When you turn a screw clockwise, raising the instrument, the bubble will move toward the position of that screw.

13

4. PREPARATION

Simply focus on the RAB code and press the [MEAS] key for an automatic reading of the staff. The following explains how to read the RAB code of the staff.

• RAB code (Random Bi-directional code) is dedicatedly used for our own automatic levels.

• The barcode tape staff is a coded staff dedicatedly used with ORION+.

Reading the staff

• Set up the staff in an area free of obstacles.• Avoid placing the staff next to mirror-like surfaces. The

effect of strong light could make measurement impossible.

• Support the staff so that it is perpendicular, checking the circular bubble scope on the staff. If the staff is tilting, height and distance measurements will be incorrect.

• If the surface is catching the light, turn it just enough to stop the reflection.

• Make sure shadows are not cast on the staff as this could make measurement impossible.

4.3 Setting Up the Staff

Barcode tape staff

Turn a few degrees to the left or right.

RAB code side of the staff

14

4. PREPARATION

• When holding the staff during measurement, make sure your hand does not cover the RAB code.

• If dark locations make measurement difficult, shine a flashlight on the staff. Stand at a distance so that the beam shines evenly over the length of the staff.

• If waterdrops or dirt adhere to the barcode, measurement may be impossible.Wipe the staff clean with a soft cloth.

• Clean the staff if grit or dirt gets stuck between the sections. If the staff is dirty, measurements will not be very accurate.

• Avoid scratching or soiling the barcode surface as this could make measurement impossible. Store and carry the staff inside its case.

• If direct sunlight or strong light enters the eyepiece during operation, measurement may not be performed. ([ 1 ] (Measurement error) or [ 4 ] (Too bright) will be displayed) 8. ERROR (p. 39)Shield the eyepiece from the light source using your body or cover the eyepiece with your hand. Measurement can be performed when the eyepiece is shielded.

• If the equipment is subjected to shock or vibration during use, measurement may not be possible. Resume measurement under more stable conditions.

Setting Up the Staff

1 Connect the staffs correctly by making sure the numbers on the numeric scale side of the staffs run in unbroken order.

2 Set the foot plate on the ground so that the staff will not sink.

3 Keeping an eye on the circular bubble scope on the staff, set the staff in the foot plate so that it stands up straight.

4 Turn the barcode scale toward the instrument.

15

4. PREPARATION

Before using the instrument

Turn the eyepiece to adjust the eyepiece image.

1 Using the gunsight, aim the objective lens toward the staff.

2 Gradually turn the eyepiece outward, stopping just before the reticle cross-lines become blurred.

3 Turn the horizontal fine motion knobs until the staff is nearly centered in the field of view, then turn the focusing knob to focus on the staff.

4 Looking through the telescope, shift your eyes slightly up and down and to each side.

5 If the staff and reticle show no deviation, the instrument is ready for use.If the staff and reticle deviate, return to step 2.

4.4 Focusing and Sighting

16

4. PREPARATION

If the cross-line blurs, or deviation occurs at step 5, errors will occur when taking measurements. Always make sure the instrument is correctly focused.

Focusing when taking measurements

1 Using the gunsight, aim the objective lens toward the staff.

2 Turn the horizontal fine motion knobs until the staff is nearly centered in the field of view, then turn the focusing knob to focus on the staff.
