Frequently Asked Questions - 303169 Brandson

How to turn on the distance meter and perform a simple measurement?

Press the ON/MEAS button to turn on the device and activate the laser. Aim at the target and press ON/MEAS again to take the measurement. The distance is displayed on the screen.

How to change the unit of measurement (m, inches, feet)?

Press the UNITS button to switch between available units: m (meter), in (inch), and ft (foot). The selected unit is displayed on the screen.

How to use the area measurement function?

Press the MENU button until the area symbol (square) appears. First measure the length, then the width by pressing ON/MEAS each time. The calculated area is automatically displayed.

How to perform indirect measurement using the Pythagorean theorem?

Press the MENU button until the desired Pythagorean symbol (triangle) appears. Follow the prompts: measure the two required distances in order. The height is calculated automatically.

What to do if the screen displays 'Err10'?

Code Err10 indicates low battery. Replace both AAA batteries with new ones.

How to clear a measurement or the last action?

Press the C/OFF button (Clear/Power Off). A single press cancels the last action or clears the current value. A long press turns off the device.

What safety precautions should be observed with the laser?

Never look into the laser beam and do not point it at people or animals.
Avoid reflective surfaces. The laser is class 2 but can cause eye injuries.

How to maintain the distance meter?

Clean it with a dry, soft cloth. Do not use aggressive cleaners. Avoid moisture, excessive heat, and shocks.

Can I use rechargeable batteries?

The manual advises against using rechargeable batteries as they may cause malfunctions. Use standard AAA alkaline batteries.

How to view the measurement history?

Press the UNITS button to access the memory. Use the + and - buttons to browse through the last 99 measurements. Press C/OFF to delete an entry.

Thank you for choosing a Brandon product. Please read the following user manual carefully so that you can enjoy the purchased product for a long time. Before using the delivered product, check that it is complete, faultless and undamaged.

Important safety guidelines for this product

Laser

• When using laser equipment, it should be ensured that people are not present in the projection range of the laser beam of the device. Ensure that the beam is not reflected to areas where people are present.
• Before using this device, inform yourself about the legal requirements and preventive measures for operating such a laser device.
• Never look into the laser beam and never point it at people or animals. Such laser radiation can cause eye injuries!
• As soon as laser radiation impinges on the eye, the eyes must be closed immediately and the head must be moved away from the laser beam immediately.
• Never point the laser beam at a mirror or other reflective surfaces. The uncontrolled beam may hit persons or animals!
• Manipulations (modifications) to the laser equipment are not permitted.
• This user manual should be kept carefully, and if you give the laser equipment away, it should be handed over along with it.
  • This product is equipped with a laser of Class 2.

5. Commissioning

Take the device out of the package and remove all the packaging material. Open the battery cover at the back of the device and insert two AAA 1.5V batteries. Then close the battery compartment. When the device is put into operation for the first time, check the intactness of the product or components and their function again.

Note: It is recommended not to use rechargeable batteries as it may lead to malfunctions.

6. Initial commissioning and initial settings

Switching on the device and the laser.

Press for a long time to switch off the device. Alternatively, the device switches to the standby mode if it is not used for approx. 3 minutes.

C/OFF "Clear/Power Off" button cancels the last action and clears the current display. In the "history", the "Clear/Power Off" button clears the currently displayed value.

6.1 Measurement reference

The position of the measurement reference edge of the device can be adjusted as desired. The desired reference point can be set using the “Measurement

reference" button ( )

The configured reference point is displayed on the top left. Restarting the device resets the configured measurement reference point to the default setting.

6.2 Selecting the measurement unit

Press the "UNITS" button to select the desired measurement unit.

The following measurement units are available: m (metre), in (inch) and ft (foot).

7. Measuring

7.1 Single distance measurement

Press the "ON" button to switch on the laser. Press this button once again to start the measurement. The measured data is subsequently shown on the display.

7.2 Continuous measurement

To perform a continuous measurement, press the "ON" button to switch on the laser. Press and hold the button once again to start the continuous measurement. The display now shows a maximum and a minimum measurement value. To stop continuous measurement, press the "C/OFF" button.

The following figure shows examples for continuous measurement:

7.3 Configuring the measurement reference

Press the button to change the measurement reference. The symbol in the display shows the point of the laser measuring device from which the measurement is being made.

8. Functions

Plus/Minus Distance measurement

+ Press the "PLUS" button in the individual measurement in order to add the next measurement value to the previous measurement value.

— Press the “MINUS” button in the individual measurement in order to subtract the next measurement value from the previous measurement value.

If you press the "CLR" button once during these steps, then the last measured value is deleted. If you then press the "CLR" button again, then the "C/OFF" function is cancelled.

Area measurement

Press the “” button to activate surface measurement. The “” symbol is shown in the display. Press the “” button to measure the length of the desired object.

Press the "button again to subsequently measure the height of the object. The corresponding measured area is now shown in the display.

Volume measurement

Press the “” button twice till the “” symbol is shown in the display.

Press the "MEAS" button to measure the length of the desired object. Then press the "MEAS" button again to measure the width of the same object. Then you must again press the "MEAS" button to measure the height of the object.

Once you have measured the 3 values, the volume of the object is shown in the display.

Special functions (Pythagoras)

This mode is meant for the automatic calculation of the Pythagorean theorem. There are three different Pythagorean measurements. Select the desired measurement and then carry out the measurement.

Press the "MENU" button once, until the desired symbol of the respective Pythagoras measurement appears in the display ("", "", ""). Press the "Switch on/Measure" button to perform the first measurement. Then measure the second desired point of the object. The respective Pythagorean side that you are currently measuring flashes in the display.

Stored measured values

"Button: Using this button you can view the last 100 stored measurements. You can scroll through the values using the "+" and "-" buttons. To delete an entry, select the corresponding measurement and press the "C/OFF" button.

Angle function

In the lower left area, the current angle to the horizontal is displayed. Notes for measurements

• If the upper surface of the object to be measured is a liquid or a clear and transparent substance, then the measurement may result in an error.
• If the object to be measured is highly reflective, then the laser may also be reflected and errors may occur in the measurement.
• If the object to be measured is very dark or hardly reflective, then the time required for measurement may increase.
• Sunlight adversely affects the range of the device!
