Safety
Warnings and Cautions
The following conventions are used to indicate safety instructions:
Warning – Warnings alert you to situations that could cause death or serious
C
injury.
Caution – Cautions alert you to situations that could cause injury or property
C
damage.
Always read and follow the instructions carefully.
Warnings
Before using the instrument, read the following warnings and follow the
instructions that they provide:
Warning – Never look at the sun through the telescope. If you do, you may
C
damage or lose your eyesight.
Warning – NPL-302 series instruments are not designed to be
C
explosion-proof. Do not use the instrument in coal mines, in areas
contaminated with coal dust, or near other flammable substances.
Warning – The NPL-302 series instrument is a Class 1 laser instrument. The
C
laser beam is hazardous to the eyes and the body. Do not sight the instrument
on the face or body of a person. If you suspect an injury caused by exposure
to the laser beam, seek medical advice immediately.
If the instrument housing is open and the instrument is turned on, the laser
emits a beam stronger than the Class 1 safety level.
Warning – Never disassemble, modify, or repair the instrument yourself. If
C
you do, you may receive electric shocks or burns, or the instrument may catch
fire. You may also impair the accuracy of the instrument.
viii Pulse Laser Station NPL-302 Series Instruction Manual
Warning – Use only the specified battery charger (part number Q-75U/E) to
C
charge the battery pack (part number BC-65). Using other chargers, such as
a charger with part number Q-7U/E or Q-7C, may cause the battery pack to
catch fire or rupture. (The BC-65 cannot be charged by the Q-7U/E or Q-7C.)
Warning – Do not cover the battery charger while the battery pack is being
C
recharged. The charger must be able to dissipate heat adequately. Coverings
such as blankets or clothing can cause the charger to overheat.
Warning – Avoid recharging the battery pack in humid or dusty places, in
C
direct sunlight, or near heat sources. Do not recharge the battery pack when it
is wet. If you do, you may receive electric shocks or burns, or the battery pack
may overheat or catch fire.
Warning – Although the battery pack (part number BC-65) has an auto-reset
C
circuit breaker, you should take care not to short circuit the contacts. Short
circuits can cause the battery pack to catch fire or burn you.
Safety
Warning – Never burn or heat the battery. Doing so may cause the battery to
C
leak or rupture. A leaking or ruptured battery can cause serious injury.
Warning – Before storing the battery pack or battery charger, cover the
C
contact points with insulation tape. If you do not cover the contact points, the
battery pack or charger may short circuit, causing fire, burns, or damage to
the instrument.
Warning – The battery BC-65 is not waterproof on its own. Do not get the
C
battery wet when it is removed from the instrument. If water seeps into the
battery, it may cause a fire or burns.

Safety
Cautions
Before using the instrument, read the following cautions and follow the instructions
that they provide:
Caution – Do not use controls or adjustments, or carry out any procedures,
C
other than those specified in this document. Otherwise you may be exposed
to hazardous radiation.
Caution – The tops of the tripod ferrules are very sharp. When handling or
C
carrying the tripod, take care to avoid injuring yourself on the ferrules.
Caution – Although a Class 1 laser is regarded as safe under normal
C
operating conditions, it is recommended that you cap the objective when the
instrument is not in use, to avoid laser emissions. Take care not to look into
the laser.
Caution – Before carrying the tripod or the instrument in the carrying case,
C
check the shoulder strap and its clasp. If the strap is damaged or the clasp is
not securely fastened, the carrying case may fall, causing personal injury or
instrument damage.
Caution – Before setting up the tripod, make sure that no-one’s hands or feet
C
are underneath it. When the legs of the tripod are being driven into the
ground, they could pierce hands or feet.
Caution – After mounting the instrument on the tripod, securely fasten the
C
thumb screws on the tripod legs. If the thumb screws are not securely
fastened, the tripod may collapse, causing personal injury or instrument
damage.

One of the benefits of the Nikon DTM-302, NPL-302, and DTM-502 series
products is ease-of-use. The software for these three product series has been
designed to make it easy for you to learn to operate one model of instrument and
apply that knowledge to the other models with little additional training. A
DTM-302 series user can easily operate the non-prism NPL-302 series instruments
or the higher accuracy DTM-502 series instruments.
There are some subtle differences in the software between these different product
families. Some of these differences stem from additional capabilities or features
available in some models. For example, the DTM-502 series offers the Lumi-Guide
functionality, which guides the rodman to the correct stake-out position quickly and
easily. The NPL-302 series offers reflectorless operation, allowing you to take
measurements to points inaccessible with a prism. This manual shows the unique
capabilities and features available in the NPL-302 series instrument.

Introduction 1
Other differences stem from the accuracy specifications of the different product
families. Each instrument model is specified to different performance levels, and the
instrument’s display resolution then varies depending on the instrument’s accuracy.
The following table describes the instrument accuracy and the corresponding angle
and distance resolution displayed on the instrument’s screen.

Maintenance 1.3
Before using the instrument, read and follow the following maintenance
instructions:
• Do not leave the instrument in direct sunlight or in a closed vehicle for
prolonged periods. Overheating the instrument may reduce its efficiency.
• If the NPL-302 series instrument has been used in wet conditions, immediately
wipe off any moisture and dry the instrument completely before returning the
instrument to the carrying case. The instrument contains sensitive electronic
assemblies which have been well protected against dust and moisture. However,
if dust or moisture gets into the instrument, severe damage could result.
• Sudden changes in temperature may cloud the lenses and drastically reduce the
measurable distance, or cause an electrical system failure. If there has been a
sudden change in temperature, leave the instrument in a closed carrying case in
a warm location until the temperature of the instrument returns to room
temperature.
• Do not store the NPL-302 series instrument in hot or humid locations. In
particular, you must store the battery pack in a dry location at a temperature of
less than 30 °C (86 °F). High temperature or excessive humidity can cause mold
to grow on the lenses. It can also cause the electronic assemblies to deteriorate,
and so lead to instrument failure.
• Store the battery pack with the battery discharged.
• When storing the instrument in areas subject to extremely low temperatures,
leave the carrying case open.
• Do not overtighten any of the clamp screws.
• When adjusting the vertical tangent screws, upper plate tangent screws, or
leveling screws, stay as close as possible to the center of each screw’s range.
The center is indicated by a line on the screw. For final adjustment of tangent
screws, rotate the screw clockwise.
• If the leveling base will not be used for an extended period, lock down the
leveling base clamp knob and tighten its safety screw.
• Do not use organic solvents (such as ether or paint thinner) to clean the
non-metallic parts of the instrument (such as the keyboard) or the painted or
printed surfaces. Doing so could result in discoloration of the surface, or in
peeling of printed characters. Clean these parts only with a soft cloth or a tissue,
lightly moistened with water or a mild detergent.

Introduction 1
• To clean the optical lenses, lightly wipe them with a soft cloth or a lens tissue
that is moistened with alcohol.
• The reticle plate cover has been correctly
mounted. Do not release it or subject it to
excessive force to make it watertight.
• Before attaching the battery pack, check
that the contact surfaces on the battery
and instrument are clean. Press the
battery pack into place until the batterymounting button rises up to the battery
pack top surface. If the battery pack is not
Reticle plate cover
attached securely, the instrument is not
watertight.
• Press the cap that covers the data output/external power input connector
terminal until it clicks into place. The instrument is not watertight if the cap is
not attached securely, or when the data output/external power input connector is
used.
• The carrying case is designed to be watertight, but you should not leave it
exposed to rain for an extended period. If exposure to rain is unavoidable, make
sure that the carrying case is placed with the Nikon nameplate facing upward.
• The BC-65 battery pack contains a Ni-MH battery. When disposing of the
battery pack, follow the laws or rules of your municipal waste system.
• The instrument can be damaged by static electricity from the human body
discharged through the data output/external power input connector. Before
handling the instrument, touch any other conductive material once to remove
static electricity.
