Produs terminatview
The POPOMAN MTM320B is a versatile green cross line laser level designed for various leveling and alignment tasks. It features a self-leveling pendulum system and can project both cross lines and two plumb dots.
Caracteristici cheie:
- Tehnologie laser verde: Provides a brighter and more visible laser line compared to red lasers, especially indoors.
- 2-Point and Cross Line Projection: Projects one horizontal line, one vertical line, and two plumb dots (up and down).
- Modul de autonivelare: Automatically levels within a 4° inclination. If the tilt exceeds 4°, the laser will blink to indicate an out-of-level condition.
- Modul manual: Allows locking the pendulum to project lines at any desired angle for non-level applications.
- Modul puls: Enables use with a laser detector (not included) for extended working distances up to 60 meters or in bright light conditions.
- Baterie reîncărcabilă USB: Equipped with a 4500mAh Lithium-Ion battery, providing up to 20 hours of continuous operation on a single charge.
- Opțiuni de montare versatile: Includes a magnetic L-bracket and a rotary base for flexible positioning. Features 1/4"-20 and 5/8"-11 threaded mounts.

Înființat
1. Încărcarea bateriei:
Before first use, ensure the battery is fully charged. The 4500mAh Lithium-Ion battery provides extended operation time.
- Locate the USB-C charging port on the device or the battery pack.
- Connect the provided USB-C cable to the device/battery and a suitable USB power source (e.g., wall adapter, power bank, computer USB port, car charger).
- The charging indicator light will show the charging status. A full charge typically takes several hours.
- Important: Remove the protective film from the battery inside the battery compartment before initial use.

2. Montarea dispozitivului:
The MTM320B offers flexible mounting options:
- On the Rotary Base: Place the laser level directly onto the included rotary base for 360-degree rotation and fine adjustment.
- With Magnetic L-Bracket: Attach the laser level to the magnetic L-bracket using the threaded mount. The bracket can then be affixed to metal surfaces or hung from screws.
- Pe un trepied: The device features 1/4"-20 and 5/8"-11 threaded mounts on its base, allowing it to be mounted on standard tripods (not included).
Instrucțiuni de operare
1. Pornire/Oprire:
To power on the device, slide the pendulum lock switch to the unlocked position. To power off, slide the switch back to the locked position. The pendulum lock also serves as a transport lock, protecting the internal mechanism.
2. Mod de autonivelare:
When the pendulum lock is in the unlocked position, the device automatically enters self-leveling mode. It will self-level within a 4° inclination. If the surface is too steep, the laser lines will blink rapidly to indicate that it is out of range. Adjust the position of the laser level until the lines stop blinking and become steady.

Figure 6: Self-Leveling and Manual Modes. The top image shows the laser in self-leveling mode, projecting a level line. The bottom image illustrates manual mode, where the laser can project lines at an angle.
3. Modul manual:
To use the device in manual mode (for projecting lines at an angle), keep the pendulum lock switch in the locked position. Press the power button to activate the laser lines. The lines will not self-level and can be projected at any angle. This is useful for tasks like installing handrails or decorative patterns.
4. Switching Laser Lines/Dots:
Press the mode button (often indicated by a laser icon or 'M') to cycle through different laser projection modes:
- Horizontal line only
- Vertical line only
- Cross lines (horizontal and vertical)
- Plumb dots only
- Cross lines + Plumb dots
5. Pulse Mode:
Activate pulse mode by pressing the dedicated pulse mode button (often indicated by a pulse icon). In pulse mode, the laser beam is modulated, allowing it to be detected by a compatible laser receiver (not included) over longer distances (up to 60m) or in brighter outdoor conditions. The indicator light for pulse mode will illuminate when active.

Întreţinere
- curatenie: Folosiți un moale, damp cloth to clean the device. Do not use abrasive cleaners or solvents. Keep the laser output windows clean for optimal performance.
- Depozitare: When not in use, store the laser level in its protective carry bag in a cool, dry place. Ensure the pendulum lock is engaged before storage or transport.
- Îngrijirea bateriei: For long-term storage, charge the battery to approximately 50% every three months to prolong its lifespan.
- Verificare calibrare: Periodically check the accuracy of the laser level. Refer to the troubleshooting section for basic calibration checks.
Depanare
| Problemă | Cauza posibila | Soluţie |
|---|---|---|
| Liniile laser clipesc rapid. | Device is out of self-leveling range (>4° inclination). | Place the device on a flatter surface or adjust its position until the lines become steady. |
| Laserul nu se pornește. | Battery is depleted or not properly inserted. Pendulum lock is engaged. | Charge the battery. Ensure the battery is correctly inserted. Slide the pendulum lock switch to the unlocked position. |
| Liniile laser sunt estompate sau invizibile. | Operating in bright light conditions. Laser output window is dirty. | Use pulse mode with a laser detector for outdoor/bright conditions. Clean the laser output window with a soft cloth. |
| Inaccurate leveling. | Device is not properly calibrated or has been subjected to severe impact. | Perform a basic calibration check (see below). If issues persist, contact customer support. |
Basic Calibration Check:
To check the accuracy of the horizontal line:
- Place the laser level on a flat surface approximately 5 meters from a wall.
- Turn on the horizontal line in self-leveling mode and mark the center of the line on the wall (Point A).
- Rotate the laser level 180 degrees without moving its base and mark the center of the line again on the wall (Point B).
- The difference between Point A and Point B should be within ±3mm at 10 meters. For 5 meters, the tolerance is ±1.5mm. If the deviation is greater, the device may require professional calibration.
