4. Nastavení
4.1 Vybalení
Carefully remove the micrometer from its packaging. Inspect the instrument for any visible damage that may have occurred during shipping. Retain the original packaging for future storage or transport.
4.2 Instalace baterie
This digital micrometer requires a battery for its display. Typically, these units use a SR44 or CR2032 type battery (battery not included). To install or replace the battery:
- Locate the battery compartment cover, usually on the side of the digital display unit.
- Use a small screwdriver or coin to gently open or slide off the cover.
- Insert the new battery with the positive (+) side facing up, ensuring correct polarity.
- Bezpečně nasaďte kryt.
4.3 Počáteční čištění
Before first use, gently wipe all measuring surfaces (anvil and spindle) with a clean, lint-free cloth. Avoid using harsh solvents or abrasive materials that could damage the surfaces or electronic components.
5. Návod k obsluze
5.1 Zapnutí/vypnutí
Stiskněte tlačítko ON/OFF button to turn the micrometer on or off. The display will illuminate when powered on.
5.2 Nastavení nuly
Accurate measurements depend on proper zero setting. Perform this step before each series of measurements or if the micrometer has been subjected to temperature changes.
- Ensure the measuring faces of the anvil and spindle are perfectly clean.
- Gently close the measuring faces by rotating the thimble using the ratchet stop until it clicks 2-3 times. This applies consistent measuring force.
- Stiskněte tlačítko NULA button. The display should now show "0.000" (or "0.0000" if in inch mode).
5.3 Unit Conversion (in/mm)
Stiskněte tlačítko in/mm button to switch between metric (millimeters) and imperial (inches) units. The selected unit will be indicated on the display.
5.4 ABS/INC Measurement
The ABS button allows switching between Absolute and Incremental measurement modes.
- Absolutní režim (ABS): This is the default mode where measurements are taken from the true zero point established during zero setting.
- Inkrementální (INC) režim: Stisknutím tlačítka ABS button will toggle to INC mode, allowing you to set a temporary zero point at any position. This is useful for comparative measurements. An "INC" indicator may appear on the display. Press ABS again to return to Absolute mode.
5.5 Provedení měření
- Open the micrometer jaws wider than the object to be measured.
- Carefully place the object between the anvil and spindle.
- Rotate the thimble using the ratchet stop until the spindle gently contacts the object and the ratchet clicks 2-3 times. This ensures consistent and repeatable measuring force, preventing overtightening.
- Odečtěte naměřenou hodnotu přímo z digitálního displeje.
- If needed, use the locking clamp to secure the spindle position before removing the object, especially for transferring readings.
6. Údržba
Proper maintenance is crucial for preserving the accuracy and lifespan of your micrometer.
- Čištění: After each use, wipe the micrometer, especially the measuring faces, with a clean, dry, lint-free cloth. For stubborn dirt or light oil, use a cloth lightly dampened with isopropyl alcohol. Ensure no liquid enters the electronic components.
- Skladování: Always store the micrometer in its protective case when not in use. Keep it in a dry, temperature-stable environment, away from direct sunlight, dust, and corrosive vapors. Slightly open the measuring faces before storage to prevent pressure on the spindle.
- Kalibrace: For critical applications or after prolonged use, regular calibration by a qualified technician is recommended to maintain certified accuracy.
- Výměna baterie: Replace the battery promptly when the display becomes dim, erratic, or stops functioning. Dispose of used batteries according to local regulations.
