1. Turn the MTTS Light Meter on.
2. Hold the MTTS Light Meter against the infant’s body as near to the
umbilical as possible and aim the Light Meter at the center of the
phototherapy light (see figure below).
- For reproducible measurements, always hold the sensor on the
same place on the infant’s body.
- Changes in the distance or angle of the light to the patient will
change the irradiance the patient receives, requiring new measure-
ments to be taken.
