1. Read the instruction manual carefully before

operation. Store it away well.

2. The warning labels on the device must never be

effaced or removed. The device is being delivered with English warning labels. Prior to the first commissioning, please paste them over with the included warning labels in your respective language. LASER RADIATION Avoid direct eye exposure Laser Class 2 IEC 60825-1:2014 Pmax≤1mW; λ=630-670nm

3. Do not focus on eyes of other people or animals.

Do not look into the laser beam and do not bundle the laser beam with optical tools. This can damage your eyes.

4. Do not let children use the laser meter unattended.

They can harm themselves or others unintentionally.18 | English LASER METER 20 PS 7520 LASER METER 20 PS 7520 English | 19

5. Do not use the device in the presence of flammable

or explosive substances. Inside the meter, sparks can emerge that may inflame the environment.

6. Only let the meter be repaired by qualified personnel

and with only the appropriate genuine parts. This way, the safety of your device will be maintained. Attention: Through severe shocks or falls, the meter might lose its measurement precision. For safety in a case of doubt, always perform a precision test at a known distance. The meter is to be protected from moisture and high heat exposure, e. g. direct insolation. Calculate some additional time to let the meter adjust to the ambient temperature.20 | English LASER METER 20 PS 7520 Technical data Effective range of measurement

max <1 mW Laser class Class II Power supply 2 x AAA Micro LR03 batteries Automatic shutdown The laser will automatically be deactivated after 30 sec. The device will automatically shut down after 3 minutes. Operating temperature 0° C to 40° C Storage temperature -10° C to 60° C Dimensions 120 × 48 × 27 mm Weight with batteries ca. 120 g

Precision within measuring range ≤ 10 m, precision ± 0,0025 m within measuring range ≤ 20 m. The range and precision are dependent on the environmental conditions. With inconvenient conditions like strong insolation and / or poorly reflecting measuring surfaces, the measurements listed might deviate .20 | English LASER METER 20 PS 7520 LASER METER 20 PS 7520 English | 21 Operation Applying and removing the clamp Through snapping-in, the mounting clap can easily be attached to the back of the device. To remove it, push the button on the bottom of the device and simultaneously slide off the clamp.

Ill. 1: Removing the mounting clamp Inserting / exchanging batteries If the mounting clamp is attached, you need to remove it first. The battery case cover can now be removed by pushing up the looking hooks and at the same time pull the cover up. Now, insert the batteries according to the marking inside the battery case. Please consider the appropriate polarity.

Ill. 2: Inserting batteries Subsequently, close the battery case cover again. Attention: Remove the batteries from the device if not in use for a longer period of time.22 | English LASER METER 20 PS 7520 Turning on / off Turn the device on or off by pressing the on / off button CLEAR until a short audio signal can be heard. The laser distance meter is immediately ready for measuring distances. After 30 seconds of disuse, the laser is being deactivated automatically, after 3 minutes without activity the entire device shuts down automatically. Setting the reference plane At the meter, two different reference planes can be selected:

• Front edge of the device, to e. g. measure from an edge

• Back edge of the device, to e. g. place it against a wall To change the reference plane, please push the button . The activated plane is being shown on the display. Ill. 3: Possible reference planes With every turn-on of the device, the reference plane is set on back edge.22 | English LASER METER 20 PS 7520 LASER METER 20 PS 7520 English | 23 Measuring functions Note: With every successful measurement, with selecting / abandon a function or with turning on or off of the device, a short audio signal sounds. If an error occurs during measuring, this will be indicated through a longer audio signal. Measuring distance Press the button CLEAR to turn on the device. The distance measuring mode is pre-set with every turning on of the meter and the symbol of distance measuring appears on the display. Target the end of the about to be measured distance and press the measuring button MEAS . The measured value appears on the display on the bottom line and a short audio signal sounds. Press the measurement button for another measuring to activate the laser. Target the end of the distance and initiate measuring by pressing the measurement button again. With every new measuring, the last measured value is displayed one line above before it will be deleted after three further measurements. This way, the last three values can be compared to the current value. With a short pressing of the button CLEAR the respective last value can be deleted.24 | English LASER METER 20 PS 7520 Measuring surfaces With the device turned on, press the button once to select measuring a surface. The symbol for surface measurement

appears on the display, the first distance of the surface flashes. Target the end of the about to be measured distance and press the measurement button MEAS once to perform the measurement. The measured value appears on the top display line while the second distance of the surface flashes. With the laser, target the end of the next distance and press the measurement button to perform a second measuring. The second measured value will be displayed in the second line. Simultaneously, the resulting surface is being calculated and is shown in the bottom line of the display. The circumference of the measured surface is additionally listed in the third display line. If you want to delete one of the measured lengths during measuring a surface, press the button CLEAR once. Afterwards, you can proceed with the measuring as before. First distance Second distance Circumference Surface 24 | English LASER METER 20 PS 7520 LASER METER 20 PS 7520 English | 25 Measuring indirect distance (Measurement via three distances) With the help of this function, you can measure hard- to-access distances (e. g. heights of exterior walls) by linking three measureable distances via trigonometrical functions with one another. With the device turned on, press the button twice to select the indirect distance measuring via three distances. The symbol for indirect distance measuring appears on the display, the first distance flashes. Target the end and press the measuring button MEAS once to perform the first measurement. The measured value appears in the top line of the display, while the second distance flashes. With the laser, target the end of the next distance and press the measuring button to measure. The measured value is being shown on the display. Continue with the third distance in an analogously way. The measured value will be listed on the display. At the same time, the resulting distance will be calculated and listed in the bottom line. For measuring an indirect distance, the three measured points need to be in one line and one measurement needs to be in a 90° angle to the measured object. If the first or last measuring point is being seized in a 90° angle (Ill. 5 a and b), the distance of the other two measuring points is respectively being listed in the bottom line of the display. If the total distance between the first and the third point is to be measured, the second point needs to be seized in a 90° angle. (Ill. 5c).26 | English LASER METER 20 PS 7520

Ill. 5: Measuring indirect distances First measured value Second measured value Third measured value Final measured value Steady measuring With the steady measuring you can easily seize minimum and maximum values. For this, the meter needs to be moved relatively towards the target whereby the mea- sured value will update every 0.5 sec. The minimum distance is being displayed in the second line and the maximum value in the third line. In the bottom line, the most current value is being displayed always.26 | English LASER METER 20 PS 7520 LASER METER 20 PS 7520 English | 27 Press the measuring button MEAS until a long audio signal can be heard and you receive the readout. Move the meter, the measured distances will be listed on the display. Short audio signals constantly indicate that the laser is active. To cancel this function, press the measuring button again or the CLEAR button. Ill. 6: Examples for the seizing of minimum or maximum values during the steady measurement Fault causes and remedies The device helps you with measuring problems by showing different codes on the display.
