[. . . ] · "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. [. . . ] 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. 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. [Distance measurement by reflector sheet mode] Position the Reflector sheet whose reflecting surface faces the aiming line to be approx. Right angle when the distance is measured by it. Right angle, there is a possibility that correct distance measurement may be impossible by dispersion or reduction of laser beam. 26 [Applied measurement range by each target mode] · When a wrong target mode is selected, a correct distance cannot be measured. Please select a correct target mode and measure. · It is sometimes possible to measure without 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. 2 Distance measurement The V-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 primary 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. · 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 SELECT CORRECTION 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. Input 25 by pressing the numeric keys. CORRECTION 1.
