Verifying Proper Operation
Verify proper operation on receipt of a new Radiometer, after servicing, and before
each use.
To verify proper operation:
1
Confirm that calibration is current by checking the calibration date sticker both
on the bottom of the sensor and on the bottom of the readout.
2
Confirm that the sensor is connected to the readout.
3
Hold the sensor near a neoBLUE phototherapy light, and press the ON/READ
button. Verify that a reading appears and that it changes as the position of the
sensor moves.
4
Release the ON/READ button, and verify that the reading continues to be
displayed for 30 seconds.
Taking Measurements
To measure overhead lights:
1
Connect the sensor to the readout.
2
Hold the sensor against the infant’s body as near to the umbilical region as
possible and aim the sensor at the center of the neoBLUE phototherapy light
(see Figure 5).

For reproducible measurements, always hold the sensor at the same place on
the infant’s body.

Changes in the distance or angle of the light to the patient will change the
intensity (irradiance) reading.
CAUTION
To avoid damage, never pull on the cable to remove the connector.

NOTE

Factory calibration of neoBLUE lights occurs at a distance of 12 inches (30 cm) from the
infant. Use or measurement of a neoBLUE light at other distances results in different
intensity readings.
