Laser Classification
Integrated distance meter
The distance meter produces a visible laser beam which emerges from the front of the instrument. It is a Class 2 laser product in accordance with: IEC60825-1:2014 “Radiation safety of laser products”.
Laser Class 2 products
Do not stare into the laser beam or direct it towards other people unnecessarily. Eye protection is normally afforded by aversion responses including the blink reflex.
WARNING:
Looking directly into the beam with an optical lens (e.g. binoculars, telescopes) can be hazardous.
Precautions
- Do not look directly into the beam with an optical lens.
CAUTION:
Looking into the laser beam may be hazardous to the eyes.
Precautions
- Do not stare into the beam. Do not look into the laser beam. Make sure the laser is aimed above or below eye level (particularly with fixed installations, in machines, etc.)
Start-up
Inserting/Replacing Batteries
- Remove the battery compartment lid and attach the hand strap.
- Insert the batteries in the correct polarity.
- Close the battery compartment.
Replace the batteries, when the display shows "203".
Only use alkaline batteries.
Remove the batteries before any long period of non-use to avoid the danger of corrosion.
Menu Functions
Setting the unit for distance measurements
- Press
for a long time to set the unit. - The following units are available: m (meter), ft (feet), in (inch), ft +/in, (feet-inch-1/16)
Beep
- Press
for a long time to turn beeps on or off.
Laser Continuous 
- Press and hold down the
button when switching on the device until 
appears permanently on the display and you hear a beep. Pressing the button again will show a distance measurement. 
Press and hold the button to switch the device and Laser continuous operation off.
Operation
Switching On or Off
- Switches on the instrument and laser. The display shows the battery symbol until the next button is pressed.
- Pressing this button for longer switches the instrument off.
- The device switches off automatically after 3 minutes of inactivity.
Clear Button
The last action is cancelled. While making area or volume measurements, single measurements can be deleted and remeasured in series.
Measuring Reference Setting
The default reference setting is from the rear of the instrument, meaning that the measurement includes the length of the device. It will show 
. on the display.
Long press 
to take the next measurement from the front edge. The display will show . Press the button, and the reference will be set to the rear again.
Measuring
Single Distance Measurement
- Press to activate the laser. Press again to trigger the distance measurement. The result will be displayed immediately.
Minimum/Maximum Measurement
This function allows the user to measure the minimum or maximum distance from a fixed measuring point. It can also be used to determine spacing. It is commonly used to measure room diagonals (maximum values) or horizontal distances (minimum values) or the difference of maximum and minimum.
- Press and hold down the button until you hear a beep. Then slowly sweep the laser back and forth, up and down over the desired target point - (e.g. into the corner of a room).
- Press to stop continuous measurement. The values for maximum and minimum distances are shown in the display as well as the last measured value in the summary line.
Functions
Addition/Subtraction Distance Measuring
- Press the button once, the next measurement is added to the previous one.
- Press the button once again, the next measurement is subtracted from the previous one.
- This process can be repeated as required, the measurement will be displayed in the summary line while the previous one displayed on the second line.
Area
- Press once. The
symbol appears in the display. - Press the button to take the first length measurement (e.g. length).
- Press it again to take the second length measurement (e.g. width).
- The result will be displayed in the summary line.
Volume
- Press the button twice. The
symbol appears in the display. - Press the button to take the first length measurement (e.g. length).
- Press the button to take the second length measurement (e.g. width).
- Press the button to take the third length measurement (e.g. height).
- The volume then appears in the summary line.
- Press the button 5 times, will add one more function "history memory", can check the stored, last 10 measurement records. The button can be used for navigation.
Indirect Measurement (Pythagoras proposition)
The instrument can calculate distances using Pythagoras proposition. Make sure you adhere to the prescribed sequence of measurement:
- All target points must be in a horizontal or vertical plane.
- The best results are achieved when the instrument is rotated about a fixed point (e.g. with the positioning bracket fully folded out and the instrument placed on a wall).
- Make sure that the first measurement and the distance to be measured are at right angle. Use the Minimum/maximum function, as explained in "Measuring -> Minimum/maximum measurement".
Indirect measurement - determining a distance using 2 auxiliary measurements
E.g. for measuring building heights. It is helpful to use a tripod.
- Press the button 3 times, the display shows
. The laser is switched on. - Aim at the upper point (1) and trigger the measurement. After the first measurement the value is adopted. The result is displayed in the summary line, the partial results will show on the second line.
- Press and hold down the button to trigger continuous measurement. Sweep the laser back and forth up and down over the ideal target point.
- Press to stop continuous measurement point (2). The result is displayed in the summary line, the partial results on the second line.
Indirect measurement - determining a distance using 3 auxiliary measurements
- Press the button 4 times, the display shows the following symbol
. The laser is switched on.
If the measurement is the horizontal distance, fix the instrument. - Let the light point direct to point (1) and point (3), read angle values on the secondary line of point (1) and (3). If less than 45°, it only needs to measure the point (1) and point (3), then it will be able to confirm the distance. Otherwise, also need to measure the point (2), to determine the distance.
- Aim at the upper point (1) and trigger the measurement. After the first measurement, the value is adopted. After the measurement, if the angle sensor is turned off, keep the instrument as horizontal as possible.
- Press and hold down the button to begin continuous measurement. Sweep the laser up and down over the ideal target point (2).
- Press to stop continuous measurement (2). The value is adopted.
- The result is displayed in the summary line, the partial results in the secondary lines.

* Use a target plate to increase the measurement range during daylight or if the target has poor reflection properties.
** Measurement accuracy could reach ±2mm in good conditions (good measurement surface, room temperature). If under adverse measuring conditions, such as the light is too strong, the temperature difference is too large or the measured surface reflects weakly, the deviation over distance will increase.
Measuring Conditions
Measuring Range
The range of 40m instrument is limited to 40m, the range of 70m instrument is limited to 70m; the range of 100m instrument is limited to 100m. At night or dusk and if the target is in shadow the measuring range without target plate is increased.
Use a target plate to increase the measurement range during daylight or if the target has poor reflection properties.
Target surfaces
Measuring errors can occur when measuring toward colourless liquids (e.g. water) or dust-free glass, Styrofoam or similar semi-permeable surfaces. Aiming at high gloss surfaces may deflect the laser beam and lead to measurement errors. Against non-reflective and dark surfaces the measuring time may increase.
