Crafted from durable stainless steel, it offers accurate and reliable measurements for both internal and external dimensions up to 150mm. Its digital display provides clear, immediate readings, enhanced by a micro-adjustment wheel for fine-tuning and a jaw lock screw to secure measurements. With switchable metric and imperial units, a high accuracy of 0.01mm, and an absolute/zero function, this vernier caliper combines user-friendly features with professional-grade precision, making it perfect for engineering, woodworking, jewellery making, and various DIY tasks.

Stainless Steel 4 Key Digital Vernier | 150mm Benefits and Features

• High Precision & Accuracy: Offers a remarkable accuracy of 0.01mm, making it suitable for tasks requiring fine tolerances.
• Digital Readout: Provides clear, instant, and easy-to-read measurements, reducing the chance of reading errors common with analogue verniers.
• Versatile Measurement Capabilities: Measures both internal (using the upper jaws) and external (using the lower jaws) dimensions, catering to a wide range of applications.
• Durable Stainless Steel Construction: Ensures long-lasting performance, resistance to corrosion, and robustness for demanding work environments.
• Micro Adjustment Wheel: Allows for extremely fine and precise movements of the slider, crucial for accurate positioning and measurement.
• Jaw Lock Screw: Securely holds the measured dimension, preventing accidental movement and allowing for precise recording or transfer of readings.
• Metric/Imperial Conversion: Easily switch between millimetres (mm) and inches, eliminating the need for manual conversions and speeding up workflow.
• Absolute/Zero Function: Enables setting a zero point at any position, facilitating comparative measurements (incremental mode) or measuring from a true zero (absolute mode).
• Ergonomic Design: The 4-key layout provides intuitive control over its various functions.

Steps to Follow For Using the Stainless Steel 4 Key Digital Vernier

Preparation:

1. Clean Workpiece: Ensure the workpiece to be measured is clean and free from dust, debris, oil, or burrs on its edges. Burrs can lead to inaccurate readings.
2. Clean Calliper: Wipe the measuring surfaces of the vernier calliper with a clean, lint-free cloth.
3. Check Battery: Ensure the battery is functional and the digital display is clear. Replace if necessary.
4. Zero Calibration: Close the jaws completely and ensure the digital display reads “0.00mm” (or “0.0000 inches”). If not, press the “ZERO” button to re-zero the tool.

Taking Measurements:

For External Measurements:

1. Open Jaws: Open the main jaws of the calliper wider than the object you wish to measure.
2. Position Object: Place the object firmly between the main jaws.
3. Close Jaws: Gently close the jaws until they make firm but not excessive contact with the object. Use the micro-adjustment wheel for fine closure.
4. Lock Jaw: Tighten the jaw lock screw to secure the measurement.
5. Read Measurement: Read the dimension directly from the digital display.

For Internal Measurements:

1. Insert Jaws: Insert the smaller, upper jaws into the opening you wish to measure.
2. Open Jaws: Open the jaws until they make firm but not excessive contact with the internal surfaces.
3. Lock Jaw: Tighten the jaw lock screw.
4. Read Measurement: Read the dimension from the digital display.

For Depth Measurements (using the depth rod):

1. Place Base: Place the flat end of the main beam (the bottom of the fixed jaw) firmly on the top surface of the object you are measuring.
2. Extend Depth Rod: Extend the depth measuring rod (located at the end of the sliding jaw) into the hole or recess until it touches the bottom.
3. Lock Jaw: Tighten the jaw lock screw.
4. Read Measurement: Read the depth from the digital display.

For Step Measurements (using the step face):

1. Position Step Face: Place the step measuring face (the end face of the main beam) on the higher surface of the step.
2. Extend Jaw: Extend the sliding jaw until its end face touches the lower surface of the step.
3. Lock Jaw: Tighten the jaw lock screw.
4. Read Measurement: Read the step height from the digital display.

After Use & Storage:

1. Clean: Wipe the calliper clean, especially the measuring surfaces, to remove any dirt, oil, or fingerprints.
2. Store Safely: Store the digital vernier in its protective case (if included) in a clean, dry, and cool place, away from magnetic objects and direct sunlight.

Health and Safety

• Handle with Care: Digital verniers are precision instruments. Avoid dropping or subjecting them to impacts, as this can affect their accuracy.
• Clean Workpiece: Always ensure the workpiece being measured is clean and has no burrs on the edges. Burrs can not only lead to inaccurate readings but also scratch the calliper’s measuring surfaces or cut your hands.
• Lathe Safety: When measuring a workpiece in a lathe or any rotating machinery, ensure that it is switched off and completely stopped before taking any measurements. This prevents serious injury.
• Keep Away from Magnetic Objects: Precision measuring tools, especially digital ones, should be kept away from strong magnetic fields as these can affect the electronic components and accuracy of the readings.
• Battery Safety: If replacing the battery, ensure it is inserted correctly and dispose of old batteries responsibly.
• Storage: Store in a protective case to prevent damage from dust, moisture, and accidental impacts.
