Auto power-off

• Instructions for Use:

1. At the data output interface of position (1), data can be output,

The interface is a capacitive grid digital measuring tool interface.

1. Press the ZERO key (3) to reset to zero at any position.
2. The mm/in button (4) can be used to convert between metric and imperial systems.
3. Automatically power off if not measured within ten minutes.
4. Battery replacement method: Use a wrench with a round back as a wrench to unscrew the battery cover,

Replace the battery with a new one (with the positive electrode facing outward), and then screw on the battery cover.

• Precautions for using digital thin film thickness gauge:

1. Before use and calibration, please verify the zero position.
2. Electronic digital display components must prevent oil, water, or other liquids from entering.
3. The micrometer screw and measuring surface must be cleaned regularly and coated with anti rust oil after use.
4. The digital thin film thickness gauge is a precision measuring tool and should be prevented from impact to avoid affecting accuracy.
5. The movement distance of the differential cylinder should be within the range of the scale sleeve's markings, and the deviation from the markings should not exceed 0.5mm.
6. When the thin film thickness gauge is not used for a long time, the battery should be removed.
