Mastercraft Digital Caliper AD9114 Instruction Manual

1. Produktüberschreitungview

The Mastercraft Digital Caliper (Model AD9114) is a precision measuring instrument designed for accurate internal, external, depth, and step measurements. It features a large LCD for easy reading, a thumb wheel for fine adjustment, and the ability to convert between metric, imperial (decimal inches), and fractional imperial units.

2. Einrichtung und Batterieinstallation

2.1. Einlegen der Batterie

The caliper requires one LR44 1.5V button cell battery. While some packages may include batteries, it is recommended to have spares. To install or replace the battery:

1. Suchen Sie die Abdeckung des Batteriefachs auf der Rückseite des digitalen Anzeigegeräts.
2. Use a small Phillips head screwdriver (if provided) to carefully remove the screw securing the battery cover.
3. Remove the cover and insert the LR44 battery with the positive (+) side facing upwards.
4. Bringen Sie die Batterieabdeckung wieder an und sichern Sie sie mit der Schraube.

Note: The caliper may turn on automatically once the battery is inserted. Ensure the battery is correctly oriented to prevent damage.

2.2. Initial Zeroing

Before taking any measurements, ensure the caliper is properly zeroed:

1. Close the measuring jaws completely, ensuring they are clean and free of debris.
2. Press the 'ZERO' button on the digital display. The display should read '0.00' (or '0.000' depending on the unit setting).

3. Bedienungsanleitung

3.1. Power On/Off and Unit Conversion

• Drücken Sie die Taste „EIN/AUS“, um den Bremssattel ein- oder auszuschalten.
• Press the 'mm/in/F' button to switch between millimeters (mm), decimal inches (in), and fractional inches (F).

3.2. Messen

The caliper can perform four types of measurements:

• Äußere Messung: Use the large jaws to measure the outside dimensions of an object. Open the jaws, place the object between them, and close the jaws until they firmly contact the object. Read the measurement on the display.
• Interne Messung: Use the small jaws at the top to measure inside dimensions. Insert the small jaws into the opening, then expand them until they firmly contact the inner surfaces. Read the measurement on the display.
• Tiefenmessung: Use the depth rod located at the end of the sliding jaw. Place the end of the main beam on the top surface of the object, then extend the depth rod until it touches the bottom of the hole or step. Read the measurement on the display.
• Schrittmessung: Use the step measuring face at the end of the main beam. Place the main beam on the higher surface and extend the sliding jaw until its step measuring face rests on the lower surface. Read the measurement on the display.

3.3. Thumb Wheel and Locking Screw

• Daumenrad: Verwenden Sie das knurled thumb wheel for precise and smooth adjustment of the sliding jaw.
• Feststellschraube: Once a measurement is taken, tighten the locking screw (located on the top of the sliding jaw) to hold the jaws in place. This prevents accidental movement and allows for easy transfer of measurements.

4. Wartung

• Reinigung: Regularly clean the caliper bar with a soft, dry cotton cloth. Avoid using harsh chemicals or abrasive materials that could damage the surface or the digital components.
• Lagerung: Store the caliper in its fitted plastic case when not in use to protect it from dust, moisture, and physical damage.
• Batteriepflege: If the caliper will not be used for an extended period, remove the battery to prevent leakage and potential damage to the electronics.

5. Fehlerbehebung

• Bildschirm schaltet sich nicht ein: Check if the battery is correctly installed and has sufficient charge. Replace the LR44 battery if necessary.
• Ungenaue Messwerte: Ensure the jaws are clean and fully closed before zeroing. Re-zero the caliper. Avoid using the caliper in environments with extreme temperature fluctuations or high humidity.
• Jaws sticking or difficult to move: Clean the caliper bar thoroughly. A very small amount of light machine oil can be applied to the sliding surfaces, but avoid getting oil on the digital sensor strip.
