Instructions for usePreparation for work:- Clean the measuring surfaces and the guide. Use a cotton cloth for this purpose. Do not use solvents or acids.
- Check the zero position by bringing the measuring surfaces together by turning the friction clutch knob only. Then press and hold the "ON/OFF•••SET" button for approximately 2 seconds until the reading resets to zero.- Check that all buttons, switches, and the display are functioning properly.Basic measurement methods:1. Absolute measurement- Loosen the retaining clamp.- Turn the device on by pressing the "ON" button. Select the measurement unit by pressing and holding the "ABS/INC•••UNIT" button for approximately 2 seconds. Each measurement will alternately be displayed in inches or millimeters. The measurement in inches is indicated by the "in" symbol on the display.
Press the "ABS/INC•••UNIT" button until the "ABS" symbol appears on the display.
- Separate the measuring surfaces slightly further than the object being measured.
- Then, turn the spindle knob to obtain a rough setting, and then continue tightening by turning the friction clutch knob. Stop tightening when the clutch engages.
- Read the measurement result on the display.2. Relative MeasurementThe measurement principle is the same as described above, but relative measurement is used to compare two dimensions.
- Pressing the "ABS/INC•••UNIT" button will reset the reading to zero, and the "INC" symbol will appear on the display. After measuring again, you can read the difference in dimensions.
The micrometer is equipped with a steel ball in a rubber mount that allows for mounting on the micrometer's measuring surface. This facilitates the measurement of small-area elements. After mounting the ball, zero the reading according to the procedure described above.
Note! It is recommended to secure the workpiece or micrometer being measured before starting the measurement. This will ensure the highest measurement accuracy. It is also recommended to perform several measurements to obtain the arithmetic mean of the results.
