• Photoelectric Receiver: Detects the reflected laser light to calculate RPM.
• ЛЦД екран: Приказује очитавања мерења, јединице и индикаторе статуса.
• Дугме МЕМ: Cycles through Maximum, Minimum, Average, and Last measurement values.
• Дугме за напајање: Укључује или искључује уређај.
• Дугме за светло: Активира или деактивира позадинско осветљење екрана.
• Одељак за батерије: Located at the rear, holds two 1.5V AAA batteries.

Сетуп

1. Инсталација батерије

1. Пронађите поклопац одељка за батерију на задњој страни уређаја.
2. Отворите поклопац.
3. Уметните две батерије од 1.5 V AAA, водећи рачуна о исправном поларитету (+/-) као што је назначено унутар одељка.
4. Добро затворите поклопац одељка за батерије.

2. Applying Reflective Tape

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

• Cut a small piece of the provided reflective tape (approximately 10-30mm long).
• Attach it to the rotating shaft, disk, or wheel where you intend to measure RPM. Ensure the tape is flat, smooth, and securely adhered to prevent detachment during rotation.
• The reflective tape provides a distinct target for the laser beam, allowing the tachometer to count rotations.

Упутство за употребу

1. Укључивање/искључивање

Притисните тастер Повер дугме () to turn the tachometer on. The LCD display will illuminate. To turn it off, press and hold the Повер button for approximately 2 seconds. The device also features an automatic shutdown function, turning off after 60 seconds of inactivity to conserve battery life.

2. Мерење

1. Ensure the reflective tape is properly applied to the rotating object.
2. Hold the tachometer firmly and point the laser beam towards the reflective tape on the rotating object. The laser emitter is located at the top front of the device.
3. Maintain a measuring distance between 50mm and 500mm (approximately 2 to 20 inches) for optimal accuracy.
4. The current RPM reading will be displayed on the LCD screen. Ensure the laser spot consistently hits the reflective tape for stable readings.

3. Using Memory Functions (MAX/MIN/AVG/LAST)

During or after a measurement session, press the МЕМ дугме () repeatedly to cycle through the stored measurement values:

• МАКС: Displays the maximum RPM recorded during the current measurement session.
• МИН: Displays the minimum RPM recorded during the current measurement session.
• Просек: Displays the average RPM calculated from the measurements taken.
• ПОСЛЕДЊЕ: Displays the last measured RPM value before entering memory mode.

4. Позадинско осветљење

Притисните тастер Светлост дугме () to turn the LCD backlight on or off. This feature improves visibility of the display in low-light conditions.

Одржавање

Чишћење

Wipe the device with a soft, dry cloth. Do not use abrasive cleaners, solvents, or corrosive chemicals, as these can damage the casing or display. Keep the laser emitter and photoelectric receiver lenses clean and free of dust or debris to ensure accurate readings.

Замена батерије

When the low battery indicator appears on the display, replace the batteries promptly to ensure continued accurate readings. Refer to the "Battery Installation" section for detailed instructions.

Складиштење

If the device will not be used for an extended period, remove the batteries to prevent leakage and potential damage. Store the tachometer in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity.
