Influence of humidity: irrelevant under 80% relative air humidity control / application for precise measurements and easy reading of 0 to 25 mm. Using method work preparation:
- Clean the measuring surfaces and guidance. Use a cotton cloth. Do not use solvents or acids.
- Check the zero position, touch the measuring surfaces by only turning the friction clutch with the button. Then keep the on / off ••• Set ”button” approx. Press for 2 seconds until the display is reset to zero.
- Check whether all buttons, switches and ads work properly.


Basic measurement methods:

1. absolutely measurement
- Loosen the clamp.
-Ut switch on the device by pressing the "On" button. Select the measuring unit by pressing the "ABS / Inc ••• Unit" button for about 2 seconds. Every time the measurement result is displayed alternately in customs or millimeters. The result in customs is described by the "In" symbol, which is displayed on the screen.
Press the "ABS / Inc ••• Unit" button until the "ABS" symbol is displayed on the display.
- Spread the measuring surfaces a little further than the measuring object.
- then roughly set by turning with the spindle button and continue tightening by turning the friction clutch button. Stop pulling when the clutch snaps in.
- Read the measurement result from the display.

2. Relative measurement
The measuring principle corresponds to the above, but the relative measurement is used to compare two dimensions.
- If you press the "ABS / Inc ••• Unit" button, the display is reset and "Inc" is displayed on the display. After again measuring, you can read the difference in the dimensions.

The micrometer is equipped with a steel ball in a rubber bearing that enables the assembly on the measuring surface of the micrometer. It facilitates the measurement of elements with a small area. After installation, the display should be reset in accordance with the procedure described above.
Note! It is recommended to assemble the workpiece or the micrometer before starting the measurement. In this way you can achieve the highest measurement accuracy. It is also recommended to carry out several measurements to obtain the arithmetic means of the results.
