• Always turn the instrument off and remove the battery before
storing the instrument in its case.
• When the instrument is placed in the carrying case, see "20.1
Standard Equipment".
• Always wipe off moisture and dirt adhering to the instrument during
survey work. Moisture or dirt on the lens may result in incorrect
readings.
• Consult your local dealer before using the instrument under special
conditions such as long periods of continuous use or high levels of
humidity. In general, special conditions are treated as being outside
the scope of the product warranty.
Maintenance
• Always clean the instrument before returning it to the case. The
lens requires special care. Dust it off with the lens brush first, to
remove tiny particles. Then, after providing a little condensation by
breathing on the lens, wipe it with the supplied cleaning cloth or
lens tissue.
• If the display is dirty, carefully wipe it with a soft, dry cloth. To clean
other parts of the instrument or the carrying case, lightly moisten a
a soft cloth in a mild detergent solution. Wring out excess water
until the cloth is slightly damp, then carefully wipe the surface of the
unit. Do not use any organic solvents or alkaline cleaning solutions.
• Store the instrument and accessories in a dry room where the
temperature remains fairly constant.
• If any trouble is found with the screws or optical parts (e.g. lens),
contact your local dealer.

5. Setting Up the Instrument
Procedure
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.
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.
Preliminaries

6. Focusing and Sighting
Procedure
• If deviation occurs at step 5, errors will occur when taking
measurements. Always make sure the instrument is correctly
focused.
Important:
• 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.
Preliminaries
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.
20
• Focusing when taking measurements
Procedure
• If the staff barcodes are out of focus, they will not be readable
and measurements cannot be taken. Make sure they are
correctly focused.
Important:
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.
Preliminaries
21
7. Basic Operation
• 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.
• 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.
Important:
7.1 Reading the Staff
Simply focus on the RAB* code 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 a coded staff
used with DL-500 line of digital levels.
Surveying
22
(Continued on next page)
(Continued from previous page)
• 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 the BGS series staff is used for leveling, and the height
difference and temperature difference are much larger than
normal, temperature variations may cause the staff to expand or
contract and cause differences in relative height measurements.
DL-502/503 reads in measurements up to 0.1mm and minor
deviations in the accuracy of the staff will adversely affect
accuracy. To obtain high accuracy measurements, it is important
to perform temperature corrections for the staff. (See the Note
below for details.)
Procedure
• 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.

• Measuring the height from a ceiling
• Not possible with Wave-and-Read function. Attempting such
measurement with the Wave-and-Read function will result in an
error.

7.2 Measuring in Status Mode
• During measurement, if direct sunlight or strong light enters the
eyepiece and measurement cannot be performed,
"Measurement error" or "Too bright" is displayed (see "17.
Warnings and Error Messages"). Shield the eyepiece from the
light source using your body or cover the eyepiece with your
hand and resume measurement.
• If the DL-502/503 is subjected to shocks or vibration during use,
measurement may be impossible. Resume measurement during
more stable conditions.
