9. Commissioning and

settings a) Switching the device On and Off

• In order to switch the laser measuring device on, push the red button (1) labelled “MEAS” and the laser warning symbol. Ensure that the laser is switched on at once and that a measurement is performed directly when you keep this button pushed.

• To switch the device off, push and hold the CLR - (10) button until the display light goes out. Switching off is acousticallyconrmed.Pushingthisbuttonbrieywillonly switch the laser off and delete the last measured value. The device will also switch off on its own if you do not use it for 3 minutes. b) Triggering a measurement

• To measure a distance (individual measurement), point the laser point at the desired position. The direct or small- est distance is measured between this position and the device.

• Hold the device steady and push the MEAS - (1) button.

• Measurement starts with a beep. Another beep follows upon a mechanical click. The measurement is now com- plete.

• The current measured value is always displayed in the bottom-most line (display area 12).50

• After a new measurement, the last two measured values aredisplayedinthelinesabove.Furthervaluesareled in the measured value storage. c) Deleting a measured value

• Torepeattheleastmeasurement,brieypushtheCLR- (10) button.

• The value is reset. Individual memory items cannot be deleted.

• Concurrent pushing of the measured value memory (7) button and the CLR (10) button will delete all saved measured values. d) Selection of the reference edge After switching on, the default measurement starts at the bottom edge of the device. Figure 4

• To switch between the reference edges, push the button (4).

• The display shows the current reference edge at the up- per left with display elements 2 / 3.51

• The measurement from the laser exit edge is signalled as measurement from the lower edge of the device by a lowerbeep.Therespectivetonealsoconrmsswitching between the edges. The device length is considered in the displayed measured result. When measuring from the lower edge, the device length is added up automatical- ly. Changes to the device length falsify the meas- uring result. e) Measuring modes Single measurement See chapter 8 b.) Triggering a Measurement Continuous single measurement

• Push and hold the (1)-MEASbutton,untiltherst sound signal is given.

• The distance between the device and the projected laser point is measured continually. The current distance is dis- played in the bottom-most line.

• To transfer it into the measured value storage, push and hold the (1)- MEAS button.

• Continuous measurement is continued and can be left with the (10) - CLR button.52 Maximum and minimum distance measurement

• In this mode, measurements are performed continually with every beep.

• When a new maximum or minimum value is found, a pre- cise measurement is performed. New extreme values in the set of all measure- ments replace the old maximum and minimum values.

• The current measured value is always displayed in the bottom-most line.

• Measured values are renewed at intervals of approx.

• Holding the (1)- MEAS button terminates the meas- urement. After 500 measurements, this measuring mode will be left automatically. MIN MAX Figure 5 Example The distance from a narrow object such as a column should be measured from a (larger) distance.

• Switch the device on via the (1)- MEAS button and target the object to be measured.53

• Switch the device to “Continuous measurement” with the (4)button.Arstmeasuredvalueisrecordedanddis- played as actual value (in the display area 12).

• Move the laser measuring point over the entire object. The measurement does not need to be triggered via the (1) - MEAS button. When the device recognises a lower minimum or a larger maximum value, a precise measurement is triggered. The lowest value from the current measurements is displayed under MIN (in the display area 10), the highest one under MAX (in the display area 11). The device may trigger additional measurements. These are displayed as actual values, but do not change the minimum and maximum values when they are in the interval between these. For a very precise measurement, limit the de- grees of freedom of movement of the device during measurement. To only turn the device around one axis, you can, e.g., support it on a level surface. The distance from the column to be measured is the minimum value. Example A tube depth can be measured the same way as described above.

• Move from one inner tube wall to the opposite inner tube wall in the middle. The total depth is displayed as the maximum value.54 Addition and subtraction measurement

• Push and hold the (5) button for adding up all subse- quent measured values to the current value or the (6) button to subtract the following measurements from the current value.

• Conduct the measurements (as described in b.)), but push the (1)- MEAS button twice. Combination of the modes is possible. For ex- ample, you can subtract the distances measured subsequently from the added values.

• For this, hold the (6) button to switch the mode. You can also switch from subtraction mode to ad- dition mode. After a measurement, the old total is displayed in the top-most line, the measured value of the recorded distance in the middle and the new total value at the bottom. The last meas- urement can be deleted and repeated via the (10) - CLR button. Example addition The total of all package dimensions must not exceed a certain limit for shipping. Choose the addition function and measure the individual edges. Example subtraction You want to measure the distance of an edge to a protrusion. However, the protrusion cannot be clearly recorded from the edge. The entire wall length is measured and the measure- ment of the protrusion is deduced with the subtraction mode.55 Area and volume measurement The area of rectangular rooms can be calculated automati- cally by measuring two edges.

• Switch to area calculation mode by pushing button 2.

• Conduct two individual measurements (as described in b.)) for the room’s edges in sequence. Ensure that you measure two adjacent orthogo- nal (perpendicular) edges.

• The display (ashing on the left) will display a symbol fortheedgetobemeasured.Therstmeasurementis displayed in the top-most display line, the second one in the middle. Measurements can be rejected with the (10) - CLR button and repeated.

• The area calculation is displayed in the bottom-most line andledinthemeasuredvaluememory.Itisevidentas area/volume via the measured unit and the corresponding symbol (display element 4). The volume calculation of a cubic room is conducted ac- cordingly.

• Switch to volume calculation mode by pushing button (2).

• Inadditiontothetworstmeasuredvaluesforthearea measurement, you also must conduct another individual measurement (as described in b.)) for the height. The distance to be measured must be orthogonal on the dis- tances measured previously.

• The new measured value is displayed in the middle line of the display. The previous one in the top-most line and the volume in the bottom line.56 Indirect measurement (with 2 measuring points) Partial measurements between two points on an area can- not be determined by an individual measurement.

• Push the (3) button once to switch to indirect measure- ment mode .

• Target the two points between which you want to calculate the distance and conduct two individual measurements (as described in b.)). Internally, the distance between the two points will be calculated by trigonometry (Pythagoras:

Make sure to measure the point that is farther awayrst.Ifyoumeasuretheshorterdistance rst, an error message (Err) will appear in the display. For correct calculation, the second distance must be orthogonal on the edge to be calculated. For a precise measurement, rotate the laser me- teratthecurrentpointaftertherstmeasurement and do not move it. Indirect measurement (with 3 measuring points) If you cannot measure from the position at which one edge is orthogonal on the edge to be calculated, three distances must be measured.

• Position yourself within the projected measuring section for the measurement.

• Push the button (3) twice until the iconashes. Start the measurement at one end point of the section to be measured.57

• Measure the distance from a point on the section to be calculated. The second distance measurement should be orthogonal again.

• Measure the end point of the section.58 f) Measurement unit change The laser measuring device LDM-100H can measure and save measured values in different units. To change the unit, push and hold the UNIT(9) button. Push and hold it again until the desired unit is shown. You can switch between the units metre (m), inch (in) and feet (ft) - in this order. New measured values are measured and displayed in the unit that has been set before. While measured values are dis- played in the measuring mode, you can switch between the units for all displayed values.
