User manual PENTAX AF400T FLASH

[. . . ] Auto focus The Auto focus may not function under every condition depending on brightness, contrast, and the shape and size of the target. In such a case, use the Power Focus buttons or the manual focus ring. Atmospheric correction During surveys for which the survey precision or atmospheric measurement method is defined, measure the atmospheric temperature and pressure separately and enter those values rather than using the Automatic Atmospheric Correction function. 7 1. Basic Operation 1. 1 Removing the Batter y (1) Rotate the knob above the battery pack counter-clockwise. 1. 2 Attaching the Batter y (1) Place the channel on the bottom of the battery pack, onto the protrusion of the instrument and push the battery pack down into place. [. . . ] 1. 7. 2 Distance measurement For a single shot measurement: [ When "Long Range Mode" is displayed ] NOTE: "Long Range Mode"is displayed only when measuring with higher laser power (in reflectorless measurement with the instrument setting "REF. LESS RANGE"set as "LONG"and "Warning Message"set as "ON") . For tracking measurement : NOTE: The number of shots can be defined. The default is "one time" The measuring modes activated by the above operations . can be also changed. NOTE: Quick mode is the function to shorten the initial measurement time using prism and reflector sheet. To set the mode, use direct command number [0][0][7][5][2][2]. When the meas key is pressed during quick mode, "<-- -->" is displayed on the screen. 1. 7. 3 Changing Target constants The default constants are: Reflecting sheet : 0mm Prism : -30mm Reflector-less : always 0mm Before changing the constants, set Target Constant in the Initial Setting to "INPUT" mode: x2 x2 x3 + To change Prism constant: input value by using : , , , x2 12 To change Sheet constant: input value by using: , , , x2 1. 7. 4 Input Temperature and Atmospheric pressure The default atmospheric correction mode is "Automatic" . Before manual input, change the default mode to "ATM INPUT" : + To Input temperature : , , , x2 x2 x2 x2 input value by using: To Input atmospheric pressure: x3 input value by using: 1. 7. 5 Laser pointer To activate Laser pointer : To quit Laser pointer : , , , x2 NOTE: The laser pointer is kept activated until it is deactivated by the above procedure. 1. 7. 6 Adjusting Laser Plummet brightness or 1. 7. 7 Adjusting LCD contrast + or 13 1. 7. 8 Adjusting Illumination brightness + for LCD (for Reticle) or 2.

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. - It takes time, longer than usual, to measure the distance exceeding 200m or to measure the distance to the object that is hard to measure. - The maximum distance that can be shown on the display is 322m in the non-prism measurement mode. - The measurement range, accuracy of distance measurement and time required to measure may be influenced by the shape, size of surface area and reflection rate of the target and its environment. * The operating time becomes shorter under the low temperature, due to the temperature dependence of the battery performance. 20 NOTICE TO THE USER OF THIS PRODUCT To assure compliance with the Safety standard 21 CFR, Chapter 1. bureau of Radiological Health requires the following information to be provided to user. : It can be dangerous to look into the beam with optical equipment such as binoculars and telescopes. 1. [. . . ] Laser radiation is emitted from this aperture. " 21 C) Warning logotype is located on the surface of the telescope: "CAUTION LASER RADIATION DO NOT STARE INTO BEAM" Or for R-300 NX models: "DANGER LASER RADIATION AVOID DIRECT EYE EXPOSURE" D) Warning label is Located near the exit aperture. 3. Caution to maintain the safety in compliance with the standard A) To maintain the safety standard, refrain from any operation, maintenance, or adjustment other than described in this instruction manual. B) Operation, maintenance or adjustment other than those specified in this instruction manual may result in hazardous radiation exposure. C) Maintenance and repair not covered in this manual must be done by an authorized Pentax dealer. [. . . ]
