Measuring Irradianc
e
The Bili-Meteris aspectroradiometer that measures the therapeutic irradiance
(radiant power) of neonatal phototherapy lights. It measures the irradiance of the
wavelengths from 425 to 475 nanometers (nm), the blue-green portion of the
spectrum, which includes the principal action spectrum of bilirubin.

per nanometer (µW/cm2/nm). Ananometer is ameasure of wavelength equal to
one-billionth of a centimeter. The term “per nanometer” indicates the average
irradiance per nanometer across the spectral band being measured, which is 50 nm
wide. This makes it possible to compare average irradiance across spectral bands of
different widths.
Instrument Response

To use the Type B-22 sensor:
1Connect the sensor to the readout.
2Hold the sensor against the infant’s body as near to the umbilical as possible
and aim the sensor at the center of the phototherapy light (see Figure 7).

Low Ba t Battery power is low; replace the battery (see page 7).
Over Range If 150 flashes on the display when
READ is pressed, the
irradiance is greater than 150 µW/cm²/nm and is out of range of
the B i li-Meter .
Error If dashes flash on the display when
READ is pressed, an error
condition is present:
The sensor may not be connected. Check the sensor
connection and verify the sensor version.
The wrong version of sensor may be connected to the digital
readout unit. The color of the sensor and readout calibration
labels must match.
The sensor may have failed. Retry the read. If the problem
continues, contact Natus Medical (see page 8 ) .
The digital readout may have failed. Retry the read. If the
problemcontinues, contact Natus Medical (see page 8 ) .
Always make sure that the entire white diffuser of the sensor is over the lighted area of the
CAUTION pad, otherwise inaccurate measurements may r
e sult.

Only qualified technicians should maintain or service this device .
Read and be familiar with this instruction manual before maintaining or servicin g
The printed circuit boards ( P C B s) contain static sensitive parts. Always use ap p ropriat e
electrostatic discharge protection, such as an electrical-grounding wrist strap, when
working with internal components.
To assure accuracy, factory-calibrate the Bili-Meter to a radiometric standard annually
( s ee page 8 ) .

Calibrating
the
Bili
-
Mete
r
The Bili-Meter was factory calibrated to a radiometric standard traceable to the
National Institute of Standards and Technology (NIST). The calibration certificate
is enclosed with this manual.
To assure continued accurate measurement of irradiance, the Bili-Metershould be
recalibrated every 12 months to aradiometric (irradiance) standard. Be
cause certain
calibration factors are stored in the Bili-Metermemory, the Bili-Metermust be
recalibrated at Natus Medical. The date of the last calibration is labeled on the
readout and sensor.
Both the readout and sensor should be returned for calibration. Bili-Meters under
warranty are recalibrated at no cost. Others are recalibrated at nominalcost. For
information on returning the Bili-Meter, see below.
Service
and
Repair
The Olympic Bili-Meterhas no customer serviceable parts, and must be returned to
Natus Medical for all repairs and parts replacement. After any service, the
Bili-Metermust be recalibrated radiometrically to assure accurate measurement
of irradiance.
Retu
r
ning
for
Calibration
or
Service
The readout and sensor must be returned together for calibration or service.
