SKF TKRS 21 Hand-Held Stroboscope

1. Introducció

The SKF TKRS 21 is a robust, hand-held stroboscope designed for visual inspection of rotating and reciprocating machinery. It allows for the apparent freezing of motion or slow-motion observation of equipment, enabling detailed inspection of components such as fan blades, belts, gears, and shafts without stopping the machinery. This instrument is essential for maintenance professionals to identify defects, monitor processes, and ensure operational efficiency in various industrial environments.

2. Informació de seguretat

Always read and understand all safety warnings and instructions before operating the SKF TKRS 21. Failure to do so may result in injury or damage to the instrument.

• Protecció ocular: The stroboscope emits intense, rapidly flashing light. Prolonged exposure can cause discomfort or, in rare cases, trigger photosensitive epileptic seizures. Avoid looking directly into the light source. If you have a history of epilepsy or light sensitivity, consult a medical professional before use.
• Entorn de funcionament: Use the stroboscope in well-ventilated areas. Do not operate in explosive atmospheres or near flammable materials.
• Seguretat elèctrica: Ensure the battery compartment is securely closed before operation. Do not attempt to open or modify the device.
• Manipulació: Handle the instrument with care. Avoid dropping or subjecting it to severe impacts.
• Manteniment: Only perform maintenance as described in this manual. Refer all other servicing to qualified SKF personnel.

5. Configuració

5.1 Instal·lació de la bateria

1. Locate the battery compartment cover at the bottom of the stroboscope handle.
2. Twist or slide the cover to open it (refer to markings on the device).
3. Insert three (3) AA batteries, ensuring correct polarity (+/-) as indicated inside the compartment.
4. Torneu a col·locar la tapa del compartiment de la bateria i fixeu-la fermament.

6. Instruccions de funcionament

6.1 Funcionament bàsic

1. Power on the stroboscope. The display will show the current flash rate, typically in RPM (revolutions per minute) or Hz (Hertz).
2. Point the stroboscope's LED array towards the rotating or reciprocating object you wish to inspect.
3. Adjust the flash rate using the control dial. Rotate the dial to increase or decrease the flash frequency.
4. Observe the object. When the stroboscope's flash rate matches the object's rotational speed, the object will appear to stand still. If the flash rate is slightly off, the object will appear to move slowly, allowing for detailed inspection.

6.2 Mode Selection (RPM/Hz)

The SKF TKRS 21 typically allows switching between RPM and Hz units for flash rate measurement. Refer to the device's specific buttons (e.g., "Mode" or "Unit") to toggle between these units. The selected unit will be displayed on the LCD screen.

6.3 Ajust fi

For precise synchronization, use the fine adjustment buttons (often marked with "fast" and "slow" arrows or similar symbols) to incrementally increase or decrease the flash rate. This allows for very accurate "freezing" of motion.

7. Manteniment

7.1 Neteja

• Ensure the stroboscope is powered off before cleaning.
• Netegeu l'exterior del dispositiu amb un damp drap. No utilitzeu netejadors abrasius, dissolvents ni productes químics agressius, ja que poden danyar el casing o pantalla.
• For the LED array and display, use a lint-free cloth.
• No submergiu el dispositiu en aigua o cap altre líquid.

7.2 Emmagatzematge

• When not in use for extended periods, remove the batteries to prevent leakage and potential damage to the device.
• Store the stroboscope in its protective carrying case in a cool, dry place, away from direct sunlight, extreme temperatures, and high humidity.
