5. Nastavení

5.1 Instalace baterie

1. Najděte kryt přihrádky na baterie na zadní straně otáčkoměru.
2. Posuňte nebo odepněte kryt pro otevření přihrádky.
3. Insert three (3) 1.5V AA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
4. Bezpečně nasaďte kryt prostoru pro baterie.

5.2 Reflective Tape Application

For accurate non-contact measurement, a piece of reflective tape must be applied to the rotating object.

1. Ensure the surface of the rotating object where the tape will be applied is clean, dry, and free of grease or dust.
2. Cut a small piece of the provided reflective tape (approximately 10-12mm in length).
3. Firmly apply the reflective tape to the rotating shaft or disk. Ensure it is flat and smooth, without wrinkles or air bubbles.
4. For best results, apply the tape perpendicular to the direction of rotation.
5. If the object is highly reflective, cover the surrounding area with non-reflective black tape or paint to prevent false readings.

6. Návod k obsluze

6.1 Provedení měření

1. Ensure batteries are installed and reflective tape is applied to the target object as described in Section 5.
2. Hold the tachometer firmly in your hand.
3. Point the laser beam towards the reflective tape on the rotating object. The detecting distance should be between 50mm and 500mm (2 to 20 inches).
4. Press and hold the "TEST" button (usually the main button on the front). The laser will activate, and the display will show the RPM reading.
5. Adjust the distance and angle slightly until a stable reading appears on the LCD. The tachometer automatically selects the appropriate range.
6. Release the "TEST" button to stop the measurement. The last measured value will remain on the display.

6.2 Funkce paměti

The DT2234C tachometer automatically stores the following values during a measurement session:

• LAST Value: The most recent measurement taken.
• MAXIMÁLNÍ hodnota: The highest RPM recorded during the measurement session.
• MINIMÁLNÍ hodnota: The lowest RPM recorded during the measurement session.

These values can typically be recalled by pressing a dedicated "MEM" or "MODE" button, or by cycling through display modes after a measurement. Refer to the device's specific button layout for exact recall procedures.

7. Údržba

7.1 Čištění

• Otřete zařízení měkkým suchým hadříkem.
• Nepoužívejte abrazivní čisticí prostředky, rozpouštědla ani agresivní chemikálie.
• Keep the laser aperture and LCD display clean and free of dust for optimal performance.

7.2 Výměna baterie

When the low battery indicator appears on the display, replace all three 1.5V AA batteries promptly to ensure accurate readings and proper device function. Refer to Section 5.1 for battery installation instructions.

7.3 Skladování

Store the tachometer in a cool, dry place away from direct sunlight and extreme temperatures. If storing for an extended period, remove the batteries to prevent potential leakage and damage to the device.
