[. . . ] PD 25 quick-start instructions Display and control panel 2 Type AA Display functions Graphical display Status indicator (measuring reference point) Main menu 3 1 Button functions Buttons for menu selection Show menu / select function Scroll forward / back in the selected menu Memory functions Button for switching on and taking measurements Press twice briefly: Take measurement Press once (long press): Begin continuous measurement (tracking) "Clear" button for clearing the display (also individual place values) and for cancelling a function (press briefly to go back step by step, press long to go back to start menu) Numeric keypad (0. . . 9) for entering identification codes and values used in calculations The measurement can be saved and identified (tagged). On pressing the button (after taking a measurement or, additionally, after a calculation), the memory menu is shown in the display: Memory locations 0-999 (assigned by the PD 25) Measurement Group code e. g. type of measurement "Decimal value" button for entering decimal values or for setting units to entered values "Equals" button, for executing a calculation, confirming an entry or accening the memory menu Switch the tool off The group and measurement codes can be entered using the numeric keypad (0. . . 9). The memory operation is confirmed by pressing the *338487* 338487 button or cancelled by pressing . PD 25 menu overview Special measuring functions Determine lengths of sides, or parts of sides, of a triangle Total length Part length Opposite side "MIN / MAX" function Determine maximum distance Determine shortest distance Mean value measurement Triangle calculations (height, angle, area) Pitched roof calculations (length of inclined section, angle, area of gable end) Set out distances Mean value from several measurements (max. [. . . ] The following example shows how 2 individually measured distances can be added together. When a tripod is used: Set the measuring reference to the tripod axis. 1) 2) Distances of over 100 m can be measured in this way. 1) Press the "measure" button. Press the "measure" button again. The first distance is measured and indicated (laser switches off). Press the "+" button for addition. Pivot the tool through 180° between measurements 1 and 2. 2) Press the "measure" button. Press the "measure" button again. The second distance is measured and indicated (laser switches off). Press the "equals" button. The total distance can then be read from the display. 38 4. Working with the PD 25 Calculation, continued Multiplication (areas / volumes) Example 1: Calculating the floor area of a room Measure the width of the room. Press "x" for multiplication. Measure the length of the room. Press the "equals" button. The floor area can then be read from the display. Example 2: Calculating the volume of a room After calculating the floor area of the room: x Press "x" for multiplication. Measure the height of the room. Press the "equals" button. The volume can then be read from the display. Consecutive calculations Consecutive calculations can also be made without pressing the "equals" button. distance x distance x distance = m3 or (distance x distance) + (distance x distance) = m2 The subtraction, square and square root functions can be used in the same way. Manually entered values or values from intermediate memory can also be used for all calculation functions. When the calculation is unrealistic (e. g. m2 x m3) the display begins to blink. 39 4. Working with the PD 25 Measuring distances indirectly In a right-angled triangle, the distance to be determined is calculated by the PD 25 according to the Pythagoras principle. Application - Determining the height of a building or other distance which cannot be measured directly. The sequence of the measuring operations described must be adhered to. When the measurements are unrealistic, this is indicated by the PD 25 which causes the display to blink. [. . . ] (The measuring reference point must be set to . ) Continued 64 9. Accessories, continued PA 421 telescopic sight Used to position the target spot exactly on objects from which measurements are taken. Do not aim the PA 421 telescopic sight at objects with highly reflective surfaces. 65 10.
