    NOTE: Do not drop the acceleration sensor. If it is dropped, replace it with a new one.
    1. Connect 3 dry batteries of 1.5 V in series.
    2. Connect the positive (+) end of the batteries to terminal 3 (SGB) of the acceleration sensor and the negative (-) end of the batteries to terminal 2 (SGG). Then measure the voltage between terminal 1 (SGFR*1, SGFL*2) and terminal 2 (SGG).
    3. Measure the voltage according to the value (s) in the table below.

      Standard Voltage 

    for RH 

    STANDARD VOLTAGE

    Tester Connection Condition Specified Condition
    1 (SGFR) - 2 (SGG) Sensor is not tilted Approx. 2.0 to 2.5 V
    Sensor is tilted Change between approx. 0.9 to 2.3 V

    for LH 

    STANDARD VOLTAGE

    Tester Connection Condition Specified Condition
    1 (SGFL) - 2 (SGG) Sensor is not tilted Approx. 2.0 to 2.5 V
    Sensor is tilted Change between approx. 0.9 to 2.3 V
    NOTE: Do not apply a voltage of higher than 6 V.

    HINT:

    The voltage may differ according to the amount that the sensor is tilted.

    If the result is not as specified, replace the acceleration sensor.
