Laser Safety Instructions

Laser Radiation Do not stare into the beam IEC 60825-1:2014 Class 2 laser product Max. power 1 mW at 650nm

• Use extreme caution when using the laser beam.
  • DO NOT point the laser towards yourself, other people's eyes or animals.
• DO NOT look directly into the laser beam. This can result in permanent eye damage if the eye's natural reflex to close does not take place.
• Keep out of reach of children. This is not a toy.
• Never direct the laser beam on o objects that can reflect light.
  • Even looking briefly into the beam can result in eye damage.
  • Any adjustment to increase the power of the laser is not permitted.
• Remove the batteries if the device breaks down or is defective.
• Otherwise, there is the danger that the laser may be inadvertently switched on. This could lead to permanent eye damage.

Before using

Before initial use, remove the protective film from the device display (10) and insert the battery.

Inserting / changing the battery

If the battery symbol appears in the display (10), the inserted battery is almost drained and must be replaced. Empty batteries can falsify the measured result.

To insert the battery proceed as follows:

• Open the battery compartment cover (12) on the back of the device. You can remove the used battery more easily with the aid of the material strip, which is inside the battery compartment. Just pull on the material strip.
• Rem ove the used battery.
• Plug the contacts of the 9 V-block battery on the contacts of the profiled plug. Make sure you fit the batteries the right way round. This is specified by the profiled shape of the contacts. Also ensure without fail that the material strip is underneath the battery.
• Insert the battery in the battery compartment and close the cover again, so that it audibly latches into place.

Start-up Measuring length

- Press the ON/OFF button (9) to switch the device on. If you do not press any button for 60s, the display (10) shuts down.

• To switch the device off manually, hold the ON/OFF button pressed down for 3 seconds, until the display goes out and a double tone signal sounds.
• Press the MODE button (8) repeatedly, until the display shows the symbol for length measurement "L" as well as the length designation 0.00m (or 0'00").
• Hold the reference area (6) of the ultrasonic rangefinder at the start point of your measurement. Hold the device in such a way, that the reference area is aligned parallel to the target area of the measurement.
• If necessary use the level indicator (7) to align the ultrasonic rangefinder horizontally. The air bubble of the level indicator should be between the two markings if the alignment is horizontal.
• Press the READ button (4). The laser diode (11) projects a dot of light onto the end point of the measurement. This dot of light will help you to correctly align the ultrasonic rangefinder. After successful measuring, the length will appear in the display.

Avoiding measuring error s

In order to avoid measuring errors, please note the following information:

- The measurement is performed by ultrasound, which travels from the ultrasonic transmitter (1) in a conical manner. The ultrasound is reflected from the target area and received by the ultrasonic receiver. The ultrasonic rangefinder calculates the measured length (Fig. B) from the travel time of the signal.

In order to guarantee an exact measurement, the following conditions must be maintained (Fig. B):

● The reference area (A) must be parallel to the target area (B).
● The distance to be measured must be between 0.6 m and 16 m long.
- There must be no objects in the conical path of the ultrasound, which could reflect the ultrasound prematurely. The conical path of the ultrasound has a width of about 6 m at a

length of 16 m.

● The target area must have a smooth surface, so that the ultrasound can be well reflected.
● Transparent surfaces, such as glass, generally reflect the ultrasound.
● The battery must not be empty. An empty battery is shown in the display (10) by the

battery symbol

- If a definitive measurement is not possible, the display shows the "Err" information. The

measurement must then be repeated.

Adding length s to gather

• Measure a length as described in the section "Measuring length". The length appears in the top line of the display (10).
• Now press the RECALL button (5). The length is transferred to the bottom line. This means that it has been saved in the aggregate memory. The character "+" appears at the top of the display. The device displays in this way, that it is ready for a new length measurement.
• Press the READ button (4). The length, which has now been measured, appears at the top of the display.
• Press the RECALL button. The measured value is then transferred to the aggregate memory, and the aggregate of the two measured lengths appears at the bottom of the display. If the measurement is an incorrect measurement, do not press the RECALL button but press the READ button again. The measured value, which is displayed at the top, is overwritten. Press the RECALL button to adopt the value into the aggregate memory.
• You can repeat this procedure as often as you wish, as long as the length of 9999.99 m is not exceeded.
