Operation

  O/ON      In the shutdown state, press the O/ON key briefly to display the power on display; Under the power on state, press the O/ON key for a short time to set zero, and press the O/ON key for about 3 seconds to shut down the machine, or the machine will shut down automatically if there is no change in the display data after several minutes.

    C        Press C to make sure the correct length of the claw.

MODE      Switch different function。

Replace claw   Select a suitable measuring claw according to the object to be measured. Generally speaking, select a large measuring claw with a large radius. The measuring jaws are numbered 10, 20, 30, 60, 100 from small to large. After replacing the measuring jaws, press the C key to change the C value (i.e. measuring jaws length). C=10, 20, 30, 60, 100 will be displayed on the screen in turn, so that the measuring jaws number corresponds to the C value.
