PRECAUTIONS REGARDING SAFETY

Usage Precautions

Surveying instruments are high-precision instruments. In order to assure that the Electronic Total Station R-300 series product which you have purchased will provide long-lasting maximum performance, the precautions in this manual must be followed.Be sure to follow these instructions and use this product properly at all times.

[Solar Observation]

WARNING

Never view the sun directly using the telescope as this may result in loss of sight. Never point the objective lens directly at the sun as this may damage internal components. When using the instr ument for solar observation, be sure to attach the special solar filter (MU64) designed for this product to the objective lens.

[Laser Beam]

Do not stare into laser beam. R-300 is a class-II Laser product. (The reflectorless type is a Class IIIa (3R) laser product.)

[EDM axis]

The R series EDM is the red visible laser beam and the beam diameter is very small.The beam is emitted from the objective center and the base plate center hole.The EDM axis is designed to coincide with the telescope sight axis but both axes may not sometimes coincide slightly according to the intense temperature change and time lapse.

[Target Constant]

Confirm the Target Constant of the instrument before measurement. If a different constant is to be used, use the correct constant of the target.The constant is stored in the instrument's memory when tur ned off.

[Reflectorless and Reflector sheet]

● The measurement range is determined by the white side of the Kodak Gray Card facing the instrument and by its surrounding brightness.

There is a possibility that the range may vary when the target does not satisfy the conditions above at survey work.

● Pay attention to following in case of distance measurement by Reflectorless. In a situation resulting in low accuracy, perform the distance measurement by Reflector sheet or Prism. (R-315N/R-325N/R-335N/R-322N/R-323N)

q There is a possibility that correct distance measurement may be impossible by

dispersion or reduction of laser beam when the laser beam comes into the target from diagonal angle.

w There is a possibility that the instrument cannot calculate correctly when

receiving reflected laser beam from forth and back directions in case of measuring the target on the road.

PENTAX R-300 (p01-19) 10/30/02 11:20 AM Page 3

PRECAUTIONS REGARDING SAFETY

e There is a possibility that synthesized values are calculated and the distance

may become longer or shorter than the actual one when the operator measure the target of slope or sphere or rugged shape.

r There is a possibility that the instrument cannot calculate correctly by

collecting the reflected laser beam from a man or a car that comes and goes in front of the target.

● When using Reflector sheet, set the Reflector sheet to have its surface be approx. ver tical to the aiming line. If it is positioned not to be approx. right angle, there is a possibility that correct distance measurement may be impossible by dispersion or reduction of laser beam.

[Battery & Charger]

● Never use any battery charger other than the BC03 battery charger as this may result in damage to the instrument.

● If water should happen to splash on the instrument or the battery, wipe it off immediately and allow it to dry in a dry location. Do not put the instr ument in the case until it is completely dry as this may result in damage to the instrument.

● Turn off the power when removing the battery from the instrument as removing the battery while the power is still on may result in damage to the instrument.

● The battery mark displayed on the instrument is only an estimate of remaining battery power and is not completely accurate. Replace the batter y quickly when it is about to run down as the time a battery lasts on one charge differs depending on conditions of ambient temperature, and the measurement mode of the instrument.

● Confirm the battery level remaining before operating.

[Auto focus]

The Auto focus mechanism is very precise but will not function under every condition. Focusing depends on brightness, contrast, the shape and size of the target. In such a case, press the AF button and focus on the target by operating the Power focus key or the AF ring.

[LD POINT, Laser pointer]

When you make a correct direction using the “LD POINT”, aim the laser beam at the wall and mark the center and then confirm the discrepancy between the reticle center and the marked point beforehand.

PENTAX R-300 (p01-19) 10/30/02 11:20 AM Page 4

PRECAUTIONS REGARDING SAFETY

[Storage and Operating Environment]

● To prevent making short-circuit when removing the battery and charger from the case and storing them, apply electrically resistant tape to the poles of the battery. Storing the battery and charger as is may result in fire or burn injur y due to short-circuit.

● Avoid storing the instrument in places subject to extreme high, low or radically fluctuating temperature. (Ambient temperature range during use: –20° C to +50° C)

● Distance measurements may take longer when atmospheric conditions are poor such as when heat shimmer is present.When storing the instr ument, always put it in its case and avoid storage in dusty location or location subject to vibration or extreme heat or humidity.

● Whenever there is a sharp temperature difference between the instrument’s storage and usage locations allow the instrument to adjust to the ambient for an hour or more before use.Be sure to protect the instrument from the sun if the location is subject to intense direct sunlight.

● During surveys for which the survey precision or atmospheric measurement method has been defined measure the atmospheric temperature and pressure separately and enter those values rather than using the Automatic Atmospheric Correction function.

● The battery should be charged approximately once per month if the instrument is to be stored for an extended period of time.The instrument should also be removed from its case occasionally and aired out.

● In addition to these precautions, be sure to handle the instrument properly at all times following the descriptions given in the various sections of this manual to assure safe and proper measurements.

[Transpor ting and Carr ying the Instr ument]

● Be careful to protect this instrument from shock of impact and excessive vibration which may result in damage during transportation and shipment.

● When transporting the instrument, always put it in the case and wrap shockabsorbing material around it and be sure it is handled as “FRAGILE”.

[Checks and Repairs]

● Always check the instrument before beginning work and check that the instrument is maintaining the proper level of precision.Pentax bears absolutely no responsibility for damages due to survey results obtained from surveys conducted without an initial instrument check.

● Never disassemble the instrument, battery or charger even if you do detect an abnormality as there is a risk of fire or electric shock due to shor t-circuit. If you think the product requires repair, contact the retail outlet where you purchased it or an authorized repair site.

Pressing [F2][TARGET] changes the target mode.

● The target mode is changed sequentially as follows. Reflector sheet - Prism - Reflectorless (reflectorless models),Reflector sheet Prism (standerd models).

● The selected target mode is stored in the memory even if the power is turned off. So, next time you can use the same mode after turning on.

● The target Constant differs according to the selected target mode. So, confirm the target mode and its Constant shown at the top screen after changing the target.

1. (Distance measurement by Reflectorless (Non-Prism) mode)

● The measurement range is determined by the white side of the Kodak Gray Card facing the instrument and by its surrounding brightness. There is a possibility that the range may vary when the target does not satisfy the conditions above at survey work.

● Pay attention to the following in case of distance measurement by Reflectorless. In case of resulting in low accuracy, perform the distance measurement by Reflector sheet or Prism.

● The Reflectorless “Long Range mode” can be accessed by the 007 CODE number 521 [REF.LESS RANGE]. The measurement range of this mode is 150m and the Laser class is IIIa.This mode can be performed by selecting the “LONG” at 1.REF.LESS RANGE.

● The CODE number 521 [REF.LESS RANGE] shows 1.REF.LESS RANGE (NORMAL/LONG) ,2.LONG RANGE MES(ON/OFF).and 3.LONG RANGE SETUP(EACH TIME/PERMANENT).

● The WARNING (Laser Power) screen is displayed when Range LONG and Message ON are selected, and then F1-MEAS key is pressed.F1-MEAS, F3NORMAL and F5-LONG are viewed.

dispersion or reduction of laser beam when the laser beam comes into the target from diagonal angle.

w There is a possibility that the instrument cannot calculate correctly when

receiving reflected laser beam from forth and back directions in case of measuring the target on the road.

e There is a possibility that synthesized values are calculated and the distance

may become longer or shorter than the actual one when the operator measures the target of slope or sphere or rugged shape.

r There is a possibility that the instrument cannot calculate correctly collecting

the reflected laser beam from a man or a car that comes and goes in front of the target.

2. Distance measurement by Reflector sheet mode

Position the Reflector sheet whose reflecting surface faces the aiming line to be approx. r ight angle when the distance is measured by it. If it is positioned not to be approx. r ight angle, there is a possibility that correct distance measurement may be impossible by dispersion or reduction of laser beam.

3. Applied measurement range by Each target mode

● (Reflectorless (Non-Prism) mode): It can measure the distance by Reflector sheet and Prism, but the measurable distance is less than 200m.

● Reflector sheet mode: It can measure the distance by Prism mode, but the measurable distance is less than 1000m.

● Prism mode: It can measure by Reflector sheet as well.

● Reflector sheet mode and Prism mode: It is sometimes possible to measure without reflector sheet or prism under special conditions like in the close distance, targeting on a wall surface. However, there is a possibility including some errors in this case, so be sure to select the Reflectorless mode.

● The target Constant should be correctly selected and confirmed in case that the Reflector sheet is used at the Prism mode and the Prism is used at the Reflector sheet mode.

6 DISTANCE MEASUREMENT

6-2 Distance Measurement

The R-300 series has two distance measurement modes of primary MEAS and second MEAS. Pressing the [F1][MEAS] one time goes to MEAS and twice goes to second MEAS. You can freely select and allocate your desired measurement mode in primar y MEAS and second MEAS by the Initial Setting 2.The “MEASURE SHOT”is set at primary MEAS and “TRACK CONT” is set at second MEAS as a Factory default setting.

● MEASURE SHOT means the Distance measurement by the Shot mode.

● MEASURE CONT means the Distance measurement by the Continuous

mode.

● TRACK SHOT means the Fast distance measurement by the Shot mode.

● TRACK CONT means the Fast distance measurement by the Continuous

mode.

Confirm the target Constant before beginning the distance measurement.

Example:“MEASURE SHOT” at primary MEAS (Factory default setting)

Collimate the telescope at a Target and press the [F1] [MEAS] once to start measuring the distance. Once distance measurement has been started, the distance measurement mark remains displayed. Upon reception of a reflected light from the Target, the instrument beeps and displays the

✽

mark to start the Shot measurement automatically.

Atmospheric Refraction and Earth Curvature Correction

● Atmospheric refraction and earth cur vature correction refers to correcting both the bending of the light beam caused by atmospheric refraction and the effect on the height differential and horizontal distance caused by the earth curvature.

● Correction called “atmospheric refraction and earth curvature correction” is initiated to correct error when the slope distance and vertical angle are caused to determine the horizontal distance and the height differential, with this instrument, the following formula is used to correct these factors.

● Calculation formula when atmospheric refraction and earth curvature correction parameter is set to “ON”:

Corrected horizontal distance (H)

Corrected vertical distance (V)

13-6 Distance Range

Generally speaking, the maximum range which can be measured varies considerably depending on the atmospheric conditions. For this reason, the Specifications illustrate the values for both Good and Normal weather conditions. It is extremely difficult to judge when weather conditions are “Good” and when they are “Normal”.With this instrument, the conditions noted below are used to differentiate between the two situations, (Good weather conditions for surveying are different from Normal weather conditions, and in surveying situations, cloudy skies are considered more favorable than sunny skies.)

Weather conditions for measurement ranges are based on the following standard values:

Normal: Visibility of approximately 20 km, with slight shimmer and moderatewind. Good: Visibility of approximately 40 km, overcast, with no shimmer and

moderate wind.
