Appendix B Reference Information
B.1.17 How long is the battery life?
The charge of the NiMH (Nickel-Metal Hydride) battery lasts about nine (9)
hours using a VNIR-only spectrometer with accessory not powered by the
instrument in an ambient environment. The charge of the NiMH battery lasts
over four (4) hours using a full-range spectrometer with a Contact Probe in an
ambient environment.
The Gel Cell rechargeable battery lasts about nine (9) hours using a
VNIR-only spectrometer with accessory not powered by the instrument in an
ambient environment. The charge of the Gel Cell battery lasts over four (4)
hours using a full-range spectrometer with a Contact Probe in an ambient
environment.
The Gel Cell rechargeable batteries are rated to give 200 to 300 uses when
they are fully drained (discharged to 9 volts) each use. Letting the battery
discharge under 9 Volts will shorten the battery's life. If the battery is only
used for 50% rated capacity up to 500 uses are possible. In the same way
using only 30% capacity can result in up to 1,000 uses.
Note:
The limiting factor for how long you can work in the field may be the battery
in the instrument controller rather than the spectrometer’s batteries.
B.1.18 What type of Ethernet cable can I use for the static IP
configuration?
The spectrometer can be plugged directly into the instrument controller using
a cross-over, shielded Ethernet cable.
When the spectrometer and instrument controller communicate over a
network, use standard shielded Ethernet cables and IP addresses compatible
with the network. The spectrometer imposes significant traffic on the
network, which can cause packet delays to other users. More importantly,
network traffic from other users can negatively impact the reliability of the
communication between spectrometer and instrument controller.
B.1.19 Can I install additional software on the instrument
controller?
Yes, but with qualifications.
The types of applications that can interfere with the measurement of data are
utility programs, network programs, and those working in the background,
such as virus checkers.
ASD programs, such as RS
3
and Indico, require real-time access to the data
that is being streamed from the TerraSpec spectrometer at a high rate of speed.
Programs running in the background can cause packets to be lost.
