• Laser radiation may be dangerous if the laser beam or a reflection enters the unprotected eye. Therefore, familiarise yourself with the statutory regulations and measures of precaution for the operation of this kind of laser device before using the laser facility.
• Never look into the laser beam and never point it at people or animals. Laser irradiation may cause eye or skin damage.
• Never point the laser beam at any mirrors or other reflecting surfaces. The uncontrolledly reflected beam may hit persons or animals. Only operate the laser in monitored areas.
• Caution! Caution - if proceeding in a different way or using any other controls than those specified in this manual, you may expose yourself to hazardous radiation.
• This product is equipped with a class 2 laser. The scope of delivery includes laser warning signs in different languages. If the notice sign on the laser is not in your local language, attach the corresponding sign to your laser.

• Never look straight into the laser light source during operation. The bright light flashes temporarily impair your eyesight. Apart from this, epileptic fits may be triggered under certain circumstances in persons sensitive to such lights. This particularly applies to epileptics.

c) Batteries/rechargeable batteries

• Do not leave any batteries/rechargeable batteries lying around openly. There is a risk of batteries being swallowed by children or pets. If swallowed, consult a doctor immediately. Danger to life!
• Leaking or damaged batteries/rechargeable batteries can cause chemical burns to skin at contact; therefore, use suitable protective gloves.
• Observe correct polarity when inserting the batteries.
• Batteries/rechargeable batteries must not be short-circuited, disassembled or thrown into fire. There is a danger of explosion!
• Never recharge normal (non-rechargeable) batteries. There is a danger of explosion!
• If not used for a longer period, remove the inserted batteries/rechargeable batteries. Overaging otherwise poses the danger of the batteries/rechargeable batteries leaking. This may cause damage to the product. Loss of guarantee/warranty!

• Never mix batteries and rechargeable batteries. Use either batteries or rechargeable batteries.
• For proper disposal of batteries/rechargeable batteries, please read the chapter "Disposal".
• Ensure that you have chosen the right reference edge of the device before measuring. For measurements from the laser exit edge or from the hand strap, choose the correct reference via button 8 and check your settings in the display at the upper left.
• Inform all persons who may work in the measurement range during the measurement of your planned measurement and be attentive. If there are any persons, animals or sensitive objects (e.g. optical electronics) in the measurement range, discontinue your measurement and switch off the device. The high-energy light of the laser may cause severe damage and injury.
• Keep the device in the enclosed bag when it is not in use. To minimise the consequences of accidental activation, insert the laser meter into the protective sleeve with its laser exit opening first.
• Removing the batteries while the device is switched on may cause measured values to be lost and not be saved permanently in the log. Switch the device off to replace the batteries. The log is then preserved even if you (briefly) remove the batteries.
• Measure only in areas that you can view completely and where you do not endanger or distract anyone.

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 acoustically confirmed. Pushing this button briefly will only 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 smallest 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 complete.

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

• After a new measurement, the last two measured values are displayed in the lines above. Further values are filed in the measured value storage.

c) Deleting a measured value

To repeat the least measurement, briefly push the CLR - (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 upper left with display elements 2 / 3 .

• The measurement from the laser exit edge is signalled as measurement from the lower edge of the device by a lower beep. The respective tone also confirms switching 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 automatically. Changes to the device length falsify the measuring result.

e) Measuring modes

Single measurement

See chapter 8 b.) Triggering a Measurement

Continuous single measurement

• Push and hold the (1) - MEAS button, until the first sound signal is given.
• The distance between the device and the projected laser point is measured continually. The current distance is displayed 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.

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 precise measurement is performed.

New extreme values in the set of all measurements 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. 0.5 s.
• Holding the (1)- MEAS button terminates the measurement. After 500 measurements, this measuring mode will be left automatically.

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.

• Switch the device to "Continuous measurement" with the (4) button. A first measured value is recorded and displayed 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 degrees 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.

Addition and subtraction measurement

• Push and hold the (5) button for adding up all subsequent 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 example, 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 addition 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 measurement 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 measurement of the protrusion is deduced with the subtraction mode.

Area and volume measurement

The area of rectangular rooms can be calculated automatically 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 orthogonal (perpendicular) edges.

• The display (flashing on the left) will display a for the edge to be measured. The first measurement is 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 and filed in the measured value memory. It is evident as area/volume via the measured unit and the corresponding symbol (display element 4).

The volume calculation of a cubic room is conducted accordingly.

• Switch to volume calculation mode by pushing button (2).
• In addition to the two first measured values for the area 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 distances 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.

Indirect measurement (with 2 measuring points)

Partial measurements between two points on an area cannot be determined by an individual measurement.

• Push the (3) button once to switch to indirect measurement 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: a^2 + b^2 = c^2 ).

Make sure to measure the point that is farther away first. If you measure the shorter distance first, an error message (Err) will appear display.

For correct calculation, the second distance must be orthogonal on the edge to be calculated.

For a precise measurement, rotate the laser meter at the current point after the first measurement 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 icon flashes. Start the measurement at one end point of the section to be measured.

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.

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 displayed in the measuring mode, you can switch between the units for all displayed values.

	Distance Area Volume
10.000 m 0.000 m2	0.000 m3
20.0 in 0.000 ft2 0.000 ft3
30.1/16 in 0.000 ft2 0.000 ft3
40.000 ft 0.000 ft2 0.000 ft3
50.000” 1/16 0.000 ft2 0.000 ft3

The values are saved in the memory with the unit chosen at the time of the measurement.

g) Display illumination

The () (9) - screen brightness button switches the display backlighting on and off. The display brightness is reduced automatically at extended inactivity. Pushing a button (other than the brightness button) switches on the display backlighting again.
