1.2.3 The radiometers measure irradiances as specified in Table 1-1.
The sensor generates electrical current proportional to the irradiance
experienced at a plane defined by the face of the sensor.
Amplification and current-to-voltage conversion circuitry are con-
tained within the hand-held display unit and its integrated nature
provides high reliability and accuracy in the readings.
1.2.4 The numerical display is a light-emitting diode (LED) for precise
reading in even total darkness. The numerals are 0.5 inch (12.7mm)
high and in a single plane for distant and wide-angle viewing.
1.3 ACCESSORIES AND REPLACEMENT PARTS
All accessories and replacement parts required for the operation of
the radiometers are listed in Table 7-1.
1.4 TECHNICAL DATA
Table 1-1 lists all the technical specifications for the radiometers.
SECTION II INSTALLATION
2.1 UNPACKING AND INSPECTION
2.1.1 Unpack and inspect the radiometer for possible damage in
shipment. Check the performance as soon as possible. If damage is
noted, notify the carrier and supplier before using the instrument.
Also check that all items are included.
2.1.2 Save the shipping carton and packing materials for future
storing or shipping of the radiometer.
2.2 POWER SOURCE REQUIREMENTS
The radiometer is battery operated. The batteries are factory
installed in the instrument.
WARNING
This radiometer is carefully designed to prevent accidental shock to
the operator when properly used. However, no engineering design
can render safe an instrument which is used carelessly. Therefore,
recommendations presented in this manual must be read carefully
and thoroughly understood before any measurements are made.
Failure to follow directions could result in serious adverse effects.
Also, certain models are designed for use in regions of the spectrum,
notably the ultraviolet range, which may be hazardous to the eyes
and/or skin of individuals. Ultraviolet protective eyewear (UVS-30
spectacles or UVG-50 goggles) and facewear (UVF-80 face shield)
are obtainable from Spectronics Corporation.
