The remaining portion of the case is designed to hold the various accessories
that may have been purchased with the instrument. There are specific
locations for the Contact Probe, Hi-Bright Muglite, Spectralon, battery pack,
and miscellaneous power cables.
WARNING! The fiber cable should never be stored with a bend of less
than a 5" diameter for long periods of time, the cable can
be damaged with undetectable longitudinal fractures that
can cause light leakage and weaker signals.
2.2 Power Supply
The FieldSpec spectroradiometer requires input power to be 12 VDC (60 W).
It does not contain an internal power supply to convert AC voltage to DC, nor
does it have internal batteries.
The three options for providing the spectroradiometer with the appropriate
DC voltage are:
• An external power supply that converts 100 VA C t o 2 4 0 VAC ( 5 0 Hz or
60
Hz) to 12 VDC (shown in Figure 2-7).
• An external battery pack that delivers 12 VDC.
• An external adapter for vehicle cigarette lighters (sold separately and
should not be used with vehicle engine running).
Use only ASD approved power supplies or connectors to
power the instrument.
