3.1 ബാറ്ററി ഇൻസ്റ്റാളേഷൻ

The caliper requires one 1.5V SR44 type battery. To install or replace the battery:

1. Locate the battery compartment cover on the back of the LCD display unit.
2. കവർ തുറക്കുക.
3. Insert the SR44 battery with the positive (+) side facing upwards.
4. ബാറ്ററി കമ്പാർട്ട്മെൻ്റ് കവർ സുരക്ഷിതമായി അടയ്ക്കുക.

3.2 പ്രാരംഭ ക്ലീനിംഗ്

Before first use, gently wipe the measuring surfaces with a clean, dry, lint-free cloth to remove any protective oils or dust.

4. അടിസ്ഥാന പ്രവർത്തനം

4.1 പവർ ഓൺ/ഓഫ്

• അമർത്തുക ഓൺ/ഓഫ് button to turn the caliper on.
• അമർത്തുക ഓൺ/ഓഫ് button again to turn the caliper off. The caliper may also automatically shut off after a period of inactivity to conserve battery.

4.2 ഡിസ്പ്ലേ പൂജ്യമാക്കുന്നു

For accurate measurements, it is crucial to zero the caliper before use:

1. Close the external jaws completely, ensuring they are clean and free of debris.
2. അമർത്തുക ZERO button. The display should now read 0.00mm or 0.000in.
3. The caliper is now ready for measurement.

4.3 യൂണിറ്റ് പരിവർത്തനം (മില്ലീമീറ്റർ/ഇഞ്ച്)

അമർത്തുക മില്ലിമീറ്റർ/ഇഞ്ച് button to switch between metric (millimeters) and imperial (inches) units at any time during measurement.

5. Measurement Techniques

Always ensure the caliper is clean and zeroed before taking measurements.

5.1 External Measurement

To measure the external dimension of an object:

1. Open the external jaws wider than the object.
2. Place the object between the external jaws.
3. Use the thumb roller to gently close the jaws until they make firm contact with the object. Do not apply excessive force.
4. എൽസിഡി ഡിസ്പ്ലേയിലെ അളവ് വായിക്കുക.

5.2 Internal Measurement

To measure the internal dimension of an object (e.g., a hole or groove):

1. Insert the internal jaws into the opening.
2. Use the thumb roller to gently open the jaws until they make firm contact with the internal surfaces.
3. എൽസിഡി ഡിസ്പ്ലേയിലെ അളവ് വായിക്കുക.

5.3 Depth Measurement

To measure the depth of a hole or step:

1. Place the end of the main scale firmly on the top surface of the object.
2. Extend the depth rod into the hole or down to the step until it touches the bottom.
3. എൽസിഡി ഡിസ്പ്ലേയിലെ അളവ് വായിക്കുക.

6. പരിപാലനവും സംഭരണവും

Proper care will ensure the longevity and accuracy of your caliper.

• വൃത്തിയാക്കൽ: After each use, wipe the caliper clean with a dry, soft cloth. Avoid using solvents or harsh chemicals, as these can damage the display or measuring surfaces.
• ബാറ്ററി കെയർ: If the caliper will not be used for an extended period, remove the battery to prevent leakage and damage.
• സംഭരണം: Store the caliper in its original plastic case with foam insert to protect it from impacts, dust, and moisture. Keep it in a dry environment away from direct sunlight and extreme temperatures.
• കേടുപാടുകൾ ഒഴിവാക്കുക: Do not drop the caliper or subject it to strong impacts. Avoid scratching the measuring surfaces.

7. പ്രശ്‌നപരിഹാരം

If you encounter issues with your caliper, refer to the following common problems and solutions:

• Display is blank or flickering:
  പരിഹാരം: Check the battery. Replace with a new 1.5V SR44 battery if necessary. Ensure the battery is inserted correctly.
• കൃത്യമല്ലാത്ത വായനകൾ:
  പരിഹാരം: Ensure the measuring surfaces are clean and free of debris. Close the jaws completely and press the ZERO button to re-zero the caliper. Avoid applying excessive force during measurement.
• Sliding jaw movement is stiff:
  പരിഹാരം: Clean the main beam and sliding surfaces with a dry, lint-free cloth. A very small amount of light machine oil can be applied to the main beam, then wiped clean to leave a thin film.
