Calibrating the Radiometer
The Radiometer 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 Radiometer should be
recalibrated every 12 months to a radiometric (irradiance) standard. Because
certain calibration factors are stored in the its memory, the Radiometer must be
recalibrated at the factory. The date of the last calibration and the date calibration is
CAUTION
Only qualified technicians should maintain or service this device.
Read and be familiar with this instruction manual before maintaining or servicing this device.
Do not allow liquid to enter the Radiometer case because this can cause electrical damage.
The printed circuit boards (PCBs) contain static sensitive parts. Always use appropriate
electrostatic discharge protection, such as an electrical-grounding wrist strap, when working with
internal components.
To assure accuracy, factory-calibrate the neoBLUE LED Phototherapy Radiometer to a
radiometric standard annually (see
).
