0.5 to 3.0 V

1 (TSL) - 3 (CLTE)

Sensor covered with cloth

0.5 V or less

2 (TSR) - 3 (CLTE)

Sensor subjected to electric light

0.5 to 3.0 V

2 (TSR) - 3 (CLTE)

Sensor covered with cloth

0.8 V or less

HINT:

  • As the inspection light is moved away from the sensor, the voltage increases.
  • Use an incandescent light for inspection. Bring it within 30 cm (11.8 in.) of the automatic light control sensor.
