[. . . ] · "Material damage" refers to damage to facilities, buildings, acquired data, etc. Before using this product, be sure that you have thoroughly read and understood this instruction manual to ensure proper operation. After reading this manual, be sure to keep it in a convenient place for easy reference. This instrument complies with the protection requirement for residential and commercial areas. [. . . ] 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. · 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. · The WARNING (Laser Power) screen is displayed when Range LONG and Message ON are selected, and then F1 - MEAS key is pressed. · 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. [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 Prism. 1 2 3 4 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 measures the target of slope or sphere or rugged shape. · If the shot count for distance measurement has been set to 2 or more in "Initial Setting 2", the distance is measured for the specified number of times to display the averaged value. Example:"TRACK CONT" at second MEAS (Factory default setting) MODE A Collimate the telescope at a Target and press [F1] [MEAS] twice in succession H. angle to start measuring the distance, H. dst. CONT target, the instrument beeps and displays MEAS TARGET the mark to start the TRACK distance measurement. 15°C P0 92° 30' 20" ((( ))) 0 SET DISP MODE 27 · If the instrument is in mode B, press [F5] [MODE] to switch to mode A and press [F1] [MEAS ] twice. · Pressing [F1] [MEAS] twice after collimating the telescope at the Target starts Continuous distance measurement at fast speed with the "MEAS" text blinking. 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 initial 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 is done in Quick Mode. 7. CORRECTION MODE 7. 1 Changing the target constant Changing the Target Constant can be performed only when the Reflector sheet and Prism Constant setting are "INPUT" in Initial Setting 1. CORRECTION Example: Prism Constant - 25mm setting Press [F4] [CORR] in mode B. (If the instrument is in mode A, press [F5] [MODE] to enter mode B. ) 1. ppm * -30mm 0mm 15°C 1013hPa 0 ppm Press the [F5] [SELECT] to enable the Prism Constant to be changed. Clear the exiting values by pressing [CLEAR] key. PRESS * 5. ppm * -25mm 0mm 15°C 1013hPa 0 ppm SELECT Press the [ENT] key to accept the Prism Constant to -25mm. MODE A H. angle 15°C P0 Pressing the [ENT] key returns the instrument to mode A. 92° 30' 20" H. dst. [. . . ] 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 favourable 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 moderate wind. Good: Visibility of approximately 40 km, overcast, with no shimmer and moderate wind. 49 12. 5 Specifications V-325 V-325N 67 SHIFT 75MM F/4. 5 LENS V-323N Telescope Magnification 30 x Resolving power 3" Field of view 2. 6% (1° 30') Minimum focus 1. 0m Distance measurement Laser Class (Visible Laser) Visible Laser:Class II Visible Laser: Class IIIR (Reflectorless), Class II (Prism) Measurement range (Good condition) Reflectorless 1. 5~300m Mini prism 1100m (1600m) 1P 3400m (4500m) 3P 4500m (5600m) Accuracy Prism 1. 5m~10m:±(3+2ppmxD)mm 10m~ :±(2mm+2pmxD)mm Reflectorless 1. 5~200m:±(5+2ppmxD)mm, 200m~:±(7+10ppmxD)mm Measuring time (minimum count) Normal 2. 0 Seconds (1mm) Track 0. 4 Seconds (1cm) Quick Mode 1. 2 Seconds (1mm) Angle measurement Measuring method Absolute rotary encoder Detection 1 side 2 side Minimum count 1" / 5" selectable Accuracy (ISO17123-3) 5" 3" Compensator Single axis Tangent screw 1 speed Sensitivity of vials Plate level (electronic) 40"/2div.
