- Éteindre: Disconnect the LENSOMETER from the main power supply.

3. Fonctionnement
Once installed, the replacement bulb operates as part of your OL-5 LENSOMETER's illumination system. Its function is to provide the necessary light for accurate measurements.
- Marche/Arrêt : The bulb will illuminate when the LENSOMETER is powered on, and turn off when the device is powered off.
- Luminosité: The brightness is controlled by the LENSOMETER's internal circuitry and is not adjustable directly from the bulb.
4. Entretien
The Technical Precision OL-5 LENSOMETER Replacement Light Bulb requires minimal maintenance. Follow these guidelines to ensure optimal performance and longevity:
- Nettoyage: If the bulb's glass surface becomes dusty or smudged, gently wipe it with a clean, dry, lint-free cloth. Avoid using abrasive cleaners or excessive moisture. Ensure the bulb is cool and the LENSOMETER is unplugged before cleaning.
- Remplacement: Replace the bulb when it burns out or if its light output significantly diminishes. The average lifespan is approximately 500 hours.
- Manutention: Always handle the bulb by its base to avoid transferring oils from your skin to the glass, which can reduce bulb life.
