If power is still present on the cable after the FILTER
option is deselected in the menu, the message center
will alternately display POWERED CABLE and FILTER
OFF.
The combination of automatic and manual noise filters
effectively filters out unwanted signals and will display
the normal waveform signature of the cable.
2.3.11 Charging the Batteries
The Model 1205CXA is powered by a rechargeable bat-
tery pack contained within the instrument. The Model
1205CXA is shipped from the manufacturing plant with
a full charge and will operate approximately 6 hours
between charges.
When the battery supply has been depleted and the
batteries need to be recharged, plug the external bat-
tery charger into the front panel charger socket and into
any common AC outlet. The front panel green LED will
light to indicate the batteries are being charged. The
LED indicator will stay illuminated while the charger is
plugged in.
The Model 1205CXA will operate while being charged
as long as the battery level indicator is above a quarter
charge. Allow at least 16 hours charging time for the
batteries to cycle from a completely discharged state
to a fully charged state. The Model 1205CXA may be
operated while the batteries are charging, but this will
increase the charging time.
The Model 1205CXA has a built-in, current-limiting
circuit which limits battery charge current. As the
batteries approach maximum charge, the charging rate
is decreased. Do not leave the batteries charging for
long periods of time; their useful life will be shortened.
The Model 1205CXA can be charged with either an AC
or DC power source with correct voltage and current
specifications.
NOTE: The Model 1205CXA may also be
charged using an optional 12 volt cigarette lighter
adapter.
2.3.12 RS-232 Interface
Model 1205CXA includes an RS-232 Interface
Connector for serial printing and the WAVE-VIEW
software option. Two serial printer drivers are available
in the setup options menu.
