Feature:_x000D_ _x000D_ The micrometer uses digital display and scale display. The two modes read the data, even if it is not powered, it will not affect the use. _x000D_ With data holding function, easy to read data. _x000D_ Large LCD display, reading data is clearer and more convenient. _x000D_ The product has a tight lock that holds and fixes the micrometer. _x000D_ Supports data conversion in mm/in units, you can get data as needed. _x000D_ _x000D_ Specification:_x000D_ Type: Digital Micrometer_x000D_ Measurement range: 0-25mm_x000D_ Resolution: 0.001 (mm)_x000D_ Benchmark rod: No_x000D_ Required batteries: lithium-ion batteries(No-include)_x000D_ Multi-function button description:_x000D_ In/mm means: metric conversion_x000D_ TOL means: tolerance test, over tolerance prompt_x000D_ Tol up means: upper tolerance_x000D_ Tol down means: lower tolerance_x000D_ OK means: within the tolerance range (preset value)_x000D_ HOLD means: data retention_x000D_ H means: data hold status (rotation data unchanged)_x000D_ R/A means: absolute/relative measurement, 2 continuous measurements_x000D_ REL 0.000 means: relative measurement status (relative zero)_x000D_ + means: positive number_x000D_ - means: negative set_x000D_ RESET means: the start value is reset_x000D_ _x000D_ Package list:_x000D_ 1 * Micrometer_x000D_ 1 * Wrench_x000D_ 1 * Plastic box_x000D_ _x000D_ Note:_x000D_ The actual product color may deviate from the photo due to light._x000D_ There may be a slight deviation in the measurement of product.
