[Laser beam]

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

[EDM axis]

The R-300X 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 turned off.
[Reflectorless and reflector sheet]
Reflectorless: The measurement range and accuracy of Reflectorless are based on the condition that laser beam is emitted perpendicular to the white side of the Kodak Gray Card. The measurement range may be influenced by the shape of the target and its environment. 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-315NX, R-325NX, R-335NX, R-322NX, R-323NX) 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.
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. 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. 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. vertical 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. In the following environments, the distance might not be able to be measured. There is a reflection things (mirror, stainless board and white wall, etc.) in the direction of the target and under too strong sun light.

[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 instrument 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 battery 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.
[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 injury 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 instrument, 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 instruments 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.

The Laser pointer function turns the laser beam on continuously to become the aiming point so that visual confirmation is possible. 1 When the [LD POINT] key is pressed after pressing the [Laser] key, the Laser pointer function is turned on. The Laser indicator is turned on and the mark on the left of the screen blinks while the Laser pointer function is operating. 2 If the [Laser] key is pressed and the [LD POINT] key is pressed while the Laser pointer function is operating, the Laser pointer function is turned off. The beam of the sun is strong and visual confirmation is difficult in daytime when out doors. The laser beam is designed not to be able to observe through the telescope. Please visually align the laser beam to the target and mark the center. Confirm the alignment (horizontal and vertical ) before measuring when performing accurate work like stake out when using the Laser pointer function. Also refer to 10-10. The EDM beam axis. Please do not look at the laser source of beam directly.
3. PREPARATION FOR SURVEYING
3.1 Centering and leveling of the instrument
[Setting up the instrument and the tripod] 1 Adjust the tripod legs so that a height suitable for observation is obtained when the instrument is set on the tripod. 2 Hang the plumb bob on the hook of the tripod, and coarse center over the station on the ground. At this time, set the tripod and fix the metal shoes firmly into the ground so that the tripod head is as level as possible, and the plumb bob coincides with the station on the ground. 3 If the tripod head is mis-leveled by the action of fixing the metal shoes into the ground, correct the level by extending or retracting each leg of the tripod.

[Leveling] 1 Rotate instrument horizontally and make two Leveling screws arbitrarily chosen parallel to the display. 2 Turn on the Electronic vial function by pushing the Laser key. Put the bubble of the Circular vial in the center of the circle when the display shows TILT OVER. 3 Turn two Leveling screws arbitrarily chosen in an opposite direction mutually and put the vial of the horizontal Electronic vial in the center. (Figure A) 4 Put the bubble of the lengthwise Electronic vial in the center by operating the Leveling screw of one remainder. (Figure B) 5 The procedures are different according to the state of the Automatic inclination correction as following.
[When using the Automatic inclination correction by 2 axes] Please read procedure 6 because the horizontal angle and the perpendicular angle error by a perpendicular axis are automatically corrected. [When using the Automatic inclination correction by 1 axis] The instrument is horizontally rotated by 180 after the bubble of the Electronic vial is adjusted on the center at a Left circle position side and confirm that the bubble of the vial is at the center at the right circle position. [When using without Automatic inclination correction] Confirm the bubble is at the center even if the instrument is rotated by each 90. 6 Confirm whether the plummet is on the ground mark. When you confirm it is not on the mark, loosen the center screw and move the instrument over the ground mark correctly and fix the instrument by a center screw. Repeat from 1 to 6

3.6 Eyepiece adjustment

[Eyepiece adjustment] The eyepiece adjustment is performed before Vertical line (single) target sighting. 1 Remove the telescope lens cap. Horizontal line 2 Point the telescope at a bright object, and rotate the eyepiece ring full counter-clockwise. 3 Look through the eyepiece, and rotate the eyepiece ring clockwise until the reticle Sight axis appears as its maximum sharpness. When looking into the eyepiece, avoid an intense Vertical lines (double) look to prevent parallax and eye fatigue. When it is hard to see the reticle due to poor brightness, press [ILLU] to illuminate it. For adjusting intensity of brightness, refer to "4-4 Adjusting Reticle Illumination.

3.7 Target sighting

[Auto focus] The Auto focus mechanism is very precise but will not function under every condition. There is a slight possibility of focusing failure owing to 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. <Target examples which are hard to focus> No contrast like a white wall Bright back light

6. DISTANCE MEASUREMENT

6.1 Target setting
The target mode and its Constant of current setting are shown at the left of the battery mark. For example in case of each Constant 0, Reflector sheet; S 0, Reflectorless (Non-Prism); N 0, Prism; P 0

MODE A H.angle 15C S0

TARGET CHANGED -40 (CONST.: 0mm) SHEET
Pressing [F2][TARGET] changes the target mode.
The target mode is changed sequentially as follows. Reflector sheet - Prism - Reflectorless (reflectorless models), Reflector sheet - Prism (standard 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.
[Distance measurement by reflectorless (Non-Prism) mode] The measurement range and accuracy of Reflectorless are based on the condition that laser beam is emitted perpendicular to the white side of the Kodak Gray Card. The measurement range may be influenced by the shape of the target and its environment. 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 200m and the Laser closs 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, F3- NORMAL and F5-LONG are viewed. Pressing [MEAS] one time selects Second MEAS setting and twice selects QUIT. And then, Normal or Long measurement is selected by pressing F3 or F5.

Example:TRACK CONT at second MEAS (Factory default setting) Collimate the telescope at a Target MODE A and press [F1] [MEAS] twice in succession H.angle to start measuring the distance, H.dst. upon reception of a reflected light from the V.dst. CONT target, the instrument beeps and displays MEAS TARGET the _ mark to start the TRACK distance measurement.

Pressing [F1] [MEAS] twice after collimating the telescope at the Target starts Continuous distance measurement at fast speed with the MEAS text blinking. It remains blinking during the measurement. If you press the [F1] [MEAS] again, Distance measurement is completed and the MEAS text stops blinking. Pressing [F4] [DISP] cycles through the sets of display items:H.angle/H.dst./V.dst. , H.angle/V.angle/S.dst. and H.angle/V.angle/H.dst./S.dst./V.dst. , Pressing the [ESC] or [F2] [TARGET] or [F5] [MODE] during fast distance measurement stops it.

6.3 Quick mode

The Quick Mode is to shorten the measuring time using prism or reflector sheet. The Quick Mode is effective to measure the distance up to 500M using prism or reflector sheet. After selecting Quick Mode from the Quick Mode setting screen, the distance measurement MODE A 15C S0 is done in Quick Mode. H.angle 20 If the quick mode is selected, H.dst. the distance measurement mark, V.dst. CONT "<-<- ->->", instead of "((( )))", is displayed

10. CHECKS AND ADJUSTMENTS
Checks and adjustments should be performed before and during measurement. The instrument should be checked after long storage and transportation. The checks should be performed in the following order.

Circular vial adj. screw

Tighten the screws equally after the above adjustment.

10.3 Vertical reticle

[Checks] 1 Set the instrument up the tripod and carefully level it. 2 Sight the target Point A with telescope. 3 Using the telescope fine adjustment screws, move Point A to the edge of the field of view by screw (Point A). 4 No adjustment is necessary if Point A moves along the vertical line of the reticle. Vertical line Line of sight axis
[Adjustments] 1 If Point A is off from the vertical line of the reticle, first remove the eyepiece cover. 2 Using the adjusting pin, loosen the four reticle adjustment screws slightly loosening each screw by the same amount, and then rotate the reticle line around the sight axis and align the vertical line of the sight axis with Point A. 3 Tighten the reticle adjustment screws again by the same amount, and repeat the check to make sure the adjustment is correct. Since the R-322NX,R-322EX,R-323NX and R-323EX have triple axis compensation, it is necessary to make other settings besides the adjustments mentioned above. For details, contact the dealers from whom the instrument was purchased.
Recticle adjusting screws
10.4 Perpendicularity of line of sight to horizontal axis
[Checks] 1 Position a target Point A at a distance 30m - 50m away from the instrument, and sight it with the telescope. 2 Loosen the telescope lock screw and turn the telescope until a point is sighted at a distance roughly equal to that of Point A. This is Point B. 3 With the telescope still reversed loosen the horizontal lock screw and rotate the instrument around the vertical axis, and sight Point A again. 4 Loosen the telescope lock screw and turn the telescope until a point is sighted at a distance equal to that of Point B. This is Point C. 5 No adjustment is necessary if Point B and C are aligned.

30-50m

[Adjustments] 1 If Points B and C are not aligned, mark Point D at 1/4 the length of the BC, from Point C in the direction of Point B. 2 Using the adjustment pin, rotate the reticle adjustment screws horizontally opposite each other (see preceding page), and move the reticle to sight Point D. 3 Repeat the check and make sure the adjustment is correct.
Since the R-322NX, R-322EX, R-323NX and R-323EX have triple axis compensation, it is necessary to make other settings besides the adjustments mentioned above. For details, contact the dealers from whom the instrument was purchased.
10.5 Vertical 0 point error
Be sure to follow check procedures mentioned below after making adjustments on reticle and perpendicularity of line of sight to horizontal axis. [Checks] 1 Set up the instrument and turn the power on. 2 Sight the telescope at any reference target A at Normal state. Read the vertical angle (y). 3 Turn the telescope and rotate the alidade. Sight the same target A again at Back state and read the vertical angle R. 4 Ify+R = 360, no further adjustment is necessary. [Adjustments] If the deviation d (y+ R - 360 ) is wide, contact your local dealer.

[Note] The measurement range may vary by measurement conditions. Normal conditions: 20km visibility with slight shimmer. Good conditions: 40km visibility, overcast, no heat, no shimmer and moderate wind. Reflector sheet: PENTAX genuine reflector sheet (5cm x 5cm). Quick Mode, wich is effective only under Normal mode (1mm) setting, functions with Prism and Reflectorless Sheet. It is incorporated in all X series models and effective up to 500m. When Quick Mode is on, the EDM accuracy using prism and reflector sheet is (3+2ppm x D)mm. When automatic correction is activated in Quick Mode, the EDM accuracy is (3 +10ppm x D)mm. EDM Measuring time varies according to distance to be measured and conditions of the environment. Reflectorless: - The measurement range and accuracy of Reflectorless are based on the condition that laser beam is emitted perpendicular to the white side of the Kodak Gray Card. - The measurement range may be influenced by the shape of the target and its environment. - The measurement range at TRACK mode is over 5m. The operating time becomes shorter under the low temperature, due to the temperature dependence of the battery performance. The points that can be recorded in one job file are maximum 2,000 measuring points (XYZ). The user can make up to 50 job files. Job history can be managed thanks to date clock recorded in each job file.
