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 measuring reference point is altered automatically. The tool takes the extended measuring reference into account and automatically corrects the distance measured by this value. Measuring from an outside corner Check the measuring reference point. 34 4. Working with the PD 25 Measuring using the self-timer The use of an extension rod can be of great assistance for measuring with the PD 25 from points where access is difficult or even impossible to reach without some form of aid. One of the two threaded bushings (1/4" tripod thread) on the PD 25 can be used for attaching an extension rod. When an extension rod is used, the delay between pressing the "measure" button and the moment at which the measurement is taken can be set with the assistance of the self-timer (delay) function. Set the delay time The measurement is taken after: 0/2/5/10/20 seconds Press the arrow button repeatedly until the desired delay has been set. 35 4. Working with the PD 25 Measuring with the aid of a target object A board, bricks or other suitable objects can be used as the target when taking a measurement from an outside edge (e. g. outside walls of houses, perimeter fences etc). Taking measurements from various surfaces Plants and trees As a rule, it is not possible to take measurements from plants and trees, even over very short distances. rough plaster), the measurement obtained is a weighted average, whereby the centre of the laser beam receives a higher weighting than the surrounding area. 36 4. Working with the PD 25 Continuous measurement (tracking) Switch the tool on. Press the "measure" button once (long press) (=tracking). The words "LASER TRACKING" appear in the display: Move the tool to another position and read the current distance from the display. To cancel tracking mode, press the button. 37 4. Working with the PD 25 Calculation Addition / subtraction (distances) Individual distances can be added or subtracted easily. 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 "+" button for addition. Pivot the tool through 180° between measurements 1 and 2. 2) Press the "measure" button. The second distance is measured and indicated (laser switches off). Press the "equals" button. 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. 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. [. . . ] The tool can also be tested at one of our repair / service centres where confirmation of inspection can be given and, when necessary, a certificate issued for your documentation. 63 9. Accessories PA 411 target plate With two different target surfaces - White, for use when reflection is excessive - Brown, when reflection is too low PA 970 sighting glasses The sighting glasses improve visibility of the laser target spot (by the factor 4-5). PA 440 data set for the PD 25 - RS232 serial interface cable for connecting the PD 25 to a PC (for data transfer) - 31/2" diskette containing the PD 25 server software PA 450 tripod adaptor With fine adjustment of the X- and Y-axis for working accurately from a tripod.
