(a) Connect 3 dry batteries of 1.5 V in series.
(b) Connect VGS terminal to the batteries' positive (+) terminal, and GGND terminal to the batteries' negative (-) terminal, apply about 4.5 V between VGS and GGND terminals.

NOTICE: Do not apply voltage of 6 V or more to terminals VGS and GGND.





(c) Check the output voltage of GL1 and GL2 terminals.

HINT:
- If the sensor is tilted too much it may show the wrong value.
