Description:
The ET50 is a digital vernier caliper, typically made of stainless steel, that provides high-precision measurements in millimeters, inches, and fractions. A common version of the ET50 is a 150mm (6-inch) model with a resolution of 0.01mm. It features an easy-to-read LCD screen for displaying measurements.
Key features:
- Measurement Range: Typically 0.01mm to 150mm (0.001 inch to 6 inches).
- Accuracy: Approximately ±0.04mm.
- Display: A clear LCD screen for easy reading of measurements.
- Power: Usually operates on a single LR44 button battery.
- Automatic functions: Includes an automatic on/off feature.
- Construction: Durable stainless steel construction.
- Conversion: Allows for easy switching between different units of measurement (mm, inches, and fractions).
- Zero calibration: A switch allows for resetting the display to zero at any point.
- Applications: Suitable for a wide range of precision measurement tasks in mechanical work, woodworking, and other DIY and industrial applications.
How to use an ET50 digital caliper:
-
Calibration: Before taking a measurement, press the zero calibration button to set the caliper to zero. Then, ensure the jaws are fully closed to confirm the calibration.
Turn On: The device may turn on automatically when you move the jaws apart. Additionally, check the display to verify that the caliper is ready for measurement.
- Measurement:
- Hold the object between the jaws to measure its external dimensions.
- Use the “rabbit ears” (the smaller jaws on top) for internal measurements.
- Extend the depth blade from the back of the caliper to measure depth.
- Read the measurement: The reading will be displayed clearly on the LCD screen.
- Hold reading: Some models allow you to clamp the movable jaw to hold a reading.
