4. Fametrahana
4.1 Famandrihana ny fitaovana
The device is equipped with a rechargeable Lithium Polymer battery. Before first use, or when the low battery indicator appears on the display, charge the device using the provided USB-C cable.
- Connect the USB-C end of the cable to the charging port on the device.
- Connect the USB-A end to a standard USB power adapter (not included) or a computer USB port.
- The charging indicator on the display will show charging status.
- Rehefa feno tanteraka dia tapaho ny tariby.

4.2 Power On/off
- Mba hampandehanana dia tsindrio ny Power/ZERO bokotra.
- Mba hialana amin'ny herinaratra, kitiho ary hazony ny Power/ZERO bokotra mandritra ny 3 segondra eo ho eo.
5. Torolàlana miasa
5.1 Measurement Modes (Absolute and Relative)
Manana fomba fandrefesana roa ity fitaovana ity:
- Absolute Measurement Mode (ABS): This is the default mode upon powering on. It measures the angle relative to a true horizontal surface (0°).
- Relative Measurement Mode (REL): Raha te hiditra amin'ity fomba ity dia tsindrio ny Power/ZERO button briefly while the device is on. The display will show 'ZERO' and then '0.00°', setting the current position as the new 0° reference. This is useful for measuring angles relative to a non-level surface.

5.2 Changing Measurement Units and Range
Tsindrio ny MODE button to cycle through the available measurement units and angle ranges:
- Diplaoma (°)
- Persentage (%)
- mm/m
- IN/FT
The device supports two angle ranges: 0-90° (4 x 90°) and 0-180°.

Image 5.2: The device displaying measurements in both 0-90° and 0-180° ranges, highlighting its magnetic V-groove for pipe attachment.
5.3 Laser Line Modes
The integrated laser can project three types of lines:
- Tsipika mitsivalana: Projects a level line.
- Tsipika mitsangana: Projects a plumb line.
- Cross-Line: Mampiseho tsipika mitsivalana sy mitsangana miaraka.
Tsindrio ny Laser ON/OFF button to cycle through these modes or turn the laser off.

Sary 5.3: Eksamples of the three laser line modes: Horizontal, Vertical, and Cross-line, demonstrating their application for finding desired slope lines.
5.4 Magnetic Base and Auto-Reversible Display
- The strong magnetic base allows the device to be securely attached to ferrous metal surfaces, freeing your hands for other tasks.
- The LCD display automatically rotates when the device is inverted, ensuring readings are always upright and easy to read.
5.5 Data Hold and Audible Buzzer
- Tsindrio ny HOLD/Buzzer button briefly to freeze the current measurement on the display. Press again to release.
- Tsindrio ary hazòny ny HOLD/Buzzer button to toggle the audible buzzer on or off. The buzzer will alert when the device is within ±1° of the horizontal (0°) or vertical (90°) position.
5.6 Famantarana ny fahadisoana
If the angle gauge is used in an incorrect position, specifically tilted diagonally over 30 degrees, the screen will display "ERROR" to prompt the user to correct the device's orientation for accurate measurement.

6. calibration
The device is factory-calibrated. However, for lasting accuracy, user calibration is possible. Perform calibration on a flat, smooth surface with a tilt no more than 5°.
- Apetraho eo amin'ny toerana fisaka sy miorina tsara ilay fitaovana.
- Tsindrio ary hazòny ny MODE bokotra, avy eo tsindrio vetivety ny Power/ZERO button. The display will show "CAL 1".
- Tsindrio ny MODE button again. The display will show "CAL 2".
- Rotate the equipment 180° on the same flat surface.
- Tsindrio ny MODE button. The display will show "CAL 2" again, then briefly show "0.00°" indicating calibration is complete.
Soso-kevitra: If the surface tilt exceeds 5° during calibration, the display will read "ERR".

7. Fikojakojana
- Diovy ny fitaovana amin'ny malefaka, damp lamba. Aza mampiasa mpanadio abrasive na solvents.
- Store the device in its protective pouch in a dry, dust-free environment when not in use.
- Fadio ny mampiharihary ny fitaovana amin'ny hafanana tafahoatra na ny tara-masoandro mivantana mandritra ny fotoana maharitra.
- Ensure the laser apertures are clean and free from obstructions for optimal performance.
