8 SENSOR CALIBRATION
Instruments are factory-calibrated and do not require any additional intervention by
users. Each sensor in the HD2402 is individually calibrated in different modes.
Luxmeter (Channel 6) , calibration is performed by comparison to the second-line
reference luxmeter used at the Delta OHM metrological laboratory; the comparison is
performed through an incandescent lamp operating at a color temperature of 2856K
(illuminant A).
UV Radiometer (Channel 2) , calibration is performed by comparison to the second-
line reference radiometer used at the Delta OHM metrological laboratory; calibration is
performed with a 270nm monochromatic light obtained at the output of a double mo-
nochromator and using a Xe-Hg lamp as a source.
UVA Radiometer (Channel 5) , calibration is performed by comparison to the sec-
ond-line reference radiometer used at the Delta OHM metrological laboratory; calibra-
tion is performed with a 365nm monochromatic light obtained by applying a 365nm
interferential filter to a Xe-Hg lamp.
BLU Radiometer (Channel 7) , calibration is performed by comparison to the sec-
ond-line reference radiometer used at the Delta OHM metrological laboratory; calibra-
tion is performed with a 440nm monochromatic light obtained by applying a 440nm
interferential filter to a halogen lamp.
IR Radiometer (Channel 3) , calibration is performed by comparison to the second-
line reference radiometer used at the Delta OHM metrological laboratory; calibration is
performed with a 680nm monochromatic light obtained by applying a 680nm interfer-
ential filter to a halogen lamp.
Pyranometer (Channel 9) , calibration is performed by comparison to the reference
pyranometer by using the light produced by a halogen lamp. Light is perpendicular to
the thermopile surface. Calibration is performed in compliance with ISO 9847 ("Cali-
bration of field pyranometers by comparison to a reference pyranometer"), method
IIc.
It is recommended to check sensor calibration at least once per year.
