SATA GL91531 Outside Micrometer 0-25mm

Key specs include a 0–25 mm measuring range, a high-resolution graduated scale for precise readings, a durable construction with hardened steel measuring surfaces, a precision spindle and anvil for smooth operation, a micrometer thimble with fine adjustment, a locking screw to secure measurements, and a protective ABS case for safe storage.

1) Clean the object to be measured. 2) Bring the spindle to lightly contact the object using the ratchet until you hear consistent, tactile click. 3) Check the reading on the scale and, if needed, use the thimble for fine adjustment. 4) Lock the measurement with the locking screw if you need to record or compare multiple parts.

Reading typically involves the main scale for whole millimeters and the thimble for the finer fractional part. The display is designed to be clear and easy to interpret, so you can quickly determine the exact outside dimension of the part being measured.

Close the spindle until the faces contact the measuring surfaces and observe the reading. If the zero point isn’t aligned, use the thimble or calibration procedure specified by SATA to set zero. Once you have the desired measurement, engage the locking screw to prevent drift during subsequent measurements.

The ratchet mechanism ensures you apply a constant, repeatable measuring force. This minimizes user-induced variation and improves measurement repeatability, which is especially important in precision work.

Keep the measuring faces clean and free from dust and debris. Wipe with a soft, dry cloth after use. Store in the included protective ABS case to protect against impact and moisture. Periodically inspect for signs of wear and ensure the locking screw operates smoothly.

It's well-suited for machining, engineering and quality-control tasks that involve checking external dimensions, verifying part tolerances, and ensuring consistent component sizing during manufacturing or prototype development.

Handle with care to avoid dropping or impacts that could misalign the spindle. Avoid forcing measurements beyond the 25 mm range. Keep the instrument clean and dry, and use the locking mechanism to prevent accidental changes during measurements.
