2.2 Konpozan Aparèy

Figi 2: Devan view of the atolla T201 with labeled buttons.
- Bouton ON/READ: Li limen aparèy la epi li kòmanse mezi yo.
- Bouton +/- INITE: Toggles between addition/subtraction and changes measurement units.
- Bouton Mezi Sifas/Volim/Endirèk: Cycles through various measurement modes.
- Bouton Istwa: Aksè a anrejistreman mezi ki estoke yo.
- Bouton Referans / Bouton Silans: Changes the measurement reference point (front/back) and mutes/unmutes sound.
- Bouton OFF/Retounen: Powers off the device or returns to the previous screen.
- Nivo ti wonn: Located on the top and side for horizontal and vertical alignment.
3. Enstalasyon
3.1 Enstalasyon batri
- Jwenn kouvèti konpatiman batri a sou dèyè aparèy la.
- Glise kouvèti a louvri.
- Mete de pil AAA, asire w polarite a kòrèk (+/-).
- Fèmen kouvèti lòj batri a byen.
3.2 Power On/Off
- Pou pouvwa sou, peze la LIKWI/LI button. The device will display the last used measurement mode.
- Pou koupe pouvwa a, peze epi kenbe OFF/Retounen button. The device also features an automatic shutdown after 3 minutes of inactivity to conserve battery life.
4. Operasyon Enstriksyon
4.1 Fikse Pwen Referans Mezi a
The device can measure from its front edge or its back edge. This is crucial for accurate measurements depending on your starting point.

Figure 3: Front and Back Measurement Reference Points.
- Peze a Reference / Mute button to toggle between the front and back reference points. An icon on the display will indicate the currently selected reference.
4.2 Chanje Inite Mezi yo
The atolla T201 supports meters, inches, and feet.

Figure 4: Changing Display Units.
- Peze a +/- INITE button to cycle through the available measurement units (m, in, ft).
4.3 Mòd Mezi
Peze a Mezi Zòn/Volim/Endirèk bouton pou sikile nan mòd sa yo:

Figure 5: Visual representation of different measurement modes.
- Mezi sèl: Peze LIKWI/LI once to activate the laser, then again to take a single distance measurement.
- Mezi Kontinyèl (Min/Max): In this mode, the device continuously measures and displays the current, minimum, and maximum distances. Press LIKWI/LI to start and again to stop.
- Mezi Zòn: The device will prompt you to measure two sides (length and width). After two measurements, it automatically calculates and displays the area.
- Mezi Volim: The device will prompt you to measure three sides (length, width, and height). After three measurements, it automatically calculates and displays the volume.
- Indirect Measurement (Pythagorean): This mode allows for indirect measurement of heights or distances using the Pythagorean theorem. Follow the on-screen prompts to take the required measurements (2 or 3 points).
4.4 Data Storage and Retrieval
The atolla T201 can store up to 20 measurement records.

Figi 6: Reviewing stored measurements.
- Peze a Istwa bouton pou view previous measurements. Use the arrow buttons to navigate through the records.
4.5 Adisyon ak Soustraksyon
- Apre ou fin pran mezi a, peze bouton an +/- INITE button to enter addition or subtraction mode. Take subsequent measurements to add or subtract them from the current value.
4.6 Oto-kalibrasyon
If you suspect measurement inaccuracies, you can perform a self-calibration. The device allows adjustment by ±7mm.
- Refer to the on-screen menu for specific instructions on initiating and completing the self-calibration process.
4.7 Fonksyon bèbè
The device can operate silently, which is useful in quiet environments.

Figure 7: Mute function for silent operation.
- Peze epi kenbe la Reference / Mute button to toggle the sound on or off.
5. Antretyen
- Netwayaj: Sèvi ak yon mou, damp twal pou netwaye aparèy la. Pa sèvi ak pwodui netwayaj abrazif oswa solvan.
- Depo: Store the device in a dry, cool place away from direct sunlight. Remove batteries if storing for extended periods.
- Ranplasman batri: Ranplase pil yo lè endikatè pil ki fèb la parèt sou ekran an.
NAN. Depanaj
| Pwoblèm | Kòz posib | Solisyon |
|---|---|---|
| Aparèy pa limen | Low or dead batteries; incorrect battery installation | Replace batteries; ensure correct polarity |
| Mezi ki pa kòrèk | Measurement reference point incorrect; device not calibrated; reflective surface issues | Check reference point; perform self-calibration; use a target plate for highly reflective/non-reflective surfaces |
| Lazè pa vizib | Bright ambient light; laser not activated | Operate in lower light conditions; press ON/READ to activate laser |
| Montre mesaj erè | Out of range; internal error | Ensure target is within range (0.15-60m); restart device |
