5. Setup
5.1. Iċċarġjar tal-Apparat
Before first use, fully charge the device. The REVASRI N40-PLUS features a built-in Lithium-Ion battery and charges via a USB Type-C port.
- Qabbad il-kejbil USB tat-Tip C provdut mal-port tal-iċċarġjar fuq l-apparat.
- Qabbad it-tarf l-ieħor tal-kejbil USB ma' adapter tal-enerġija USB standard (eż., ċarġer tat-telefon, port USB tal-kompjuter, power bank).
- The battery indicator on the display will show the charging status. A full charge allows for approximately 8,000-10,000 measurements.

Figura 5.1: Illustration of the USB Type-C charging port and connection with the charging cables.
5.2. Power On/Off
- Biex Tixgħel: Agħfas il- MEAS/ON buttuna. Id-displej se jixgħel.
- Biex Tifi: Agħfas u żomm il- Ċara / Mitfi Agħfas il-buttuna għal ftit sekondi. L-apparat jintefa wkoll awtomatikament wara perjodu ta’ inattività biex jiffranka l-batterija.
5.3. Tibdil tal-Unitajiet tal-Kejl
To switch between meters (M), inches (In), and feet (Ft):
- Waqt li l-apparat ikun mixgħul, agħfas fil-qosor il-buttuna Function/Unit button until your desired unit is displayed.
5.4. Setting Reference Point
The device can measure from its front or rear edge. The default is usually the rear edge.

Figura 5.2: Diagram illustrating how to set the baseline for measurement from different positions of the device (front or rear) to meet various measurement requirements.
- Agħfas il- Punt ta' Referenza button to toggle between the front and rear reference points. An icon on the display will indicate the active reference point.
6. Istruzzjonijiet Operattivi
The REVASRI N40-PLUS offers multiple measurement modes for various applications.

Figura 6.1: Fuqview of available measurement models including single measurement, area, volume, continuous measurement, Pythagorean measurement, data storage, HD screen, and horizontal bubbles.

Figura 6.2: Eż. viżwaliamples of various measurement methods: Single measurement, Continuous measurement, Area measurement, and Pythagorean measurement.
6.1. Kejl tad-Distanza Uniku
This is the basic mode for measuring the linear distance between two points.
- Kun żgur li l-apparat ikun mixgħul.
- Ipponta l-lejżer lejn il-mira.
- Agħfas il- MEAS/ON button once. The laser will activate.
- Agħfas il- MEAS/ON button again to take the measurement. The result will be displayed instantly.
6.2. Continuous Measurement (Tracking)
This mode allows for dynamic measurement, displaying the maximum, minimum, and current distances as you move the device.
- Agħfas il- Function/Unit button repeatedly until the continuous measurement icon (often a series of lines or a tracking symbol) appears on the display.
- Agħfas il- MEAS/ON button to start continuous measurement.
- Move the device slowly towards or away from the target. The display will update in real-time with Max, Min, and current values.
- Agħfas il- MEAS/ON Agħfas il-buttuna mill-ġdid biex twaqqaf il-kejl kontinwu.
6.3. Kejl taż-Żona
To calculate the area of a rectangular space (Length x Width).
- Agħfas il- Function/Unit button until the area measurement icon (a square) appears.
- Take the first measurement (e.g., length) by pointing the laser and pressing MEAS/ON.
- Take the second measurement (e.g., width) by pointing the laser and pressing MEAS/ON.

8 Issolvi l-problemi
| Problema | Kawża Possibbli | Soluzzjoni |
|---|---|---|
| Cannot get a reading / Display shows error. | Measurement range too short (minimum 5 yards/meters). Measuring through glass or highly reflective surfaces. Target is outside the allowable range. Signal too weak (Error 157). | Ensure target is within the minimum and maximum range. Avoid measuring through transparent or highly reflective materials. Use a reflective target plate if the surface is difficult to measure or the distance is long. |
| Kejl mhux preċiż. | Environmental factors (rain, fog, strong light, heavy dust). Device not held steady. Incorrect reference point selected. | Perform measurements in stable environmental conditions. Hold the device firmly or place it on a stable surface. Verify the correct reference point (front/rear) is selected. |
| Laser point difficult to see. | Strong ambient light (e.g., direct sunlight). | Use the device in lower light conditions if possible. Consider using a laser target plate or a specialized laser viewing glasses (not included). |
| L-apparat ma jixgħelx. | Il-batterija hija eżawrita. | Iċċarġja l-apparat billi tuża l-kejbil USB tat-Tip C provdut. |
