○

Red

: Out of measuring area (Piston is fully floating or in the bottom)

○

Yellow

: Instability area (Piston is a little float or down)

○

Green

: Measurable area

⑤

In order to reduce the friction of the piston and the cylinder, rotate the piston.

1) Red Button Only :

When this button is pressed, motor works then piston rotates always. If

piston is fully float or in the bottom, piston does not rotate and motor rotates

only. Even piston is in out of measuring area, motor always works therefore

we recommend between measurable area.

2) Red+Green Button : When these buttons are pressed, motor works and

piston rotates when piston is in measurable area. Automatically stop the

piston and motor rotation when piston is in out of measuring area.
