Tektronix TDS3BAT Betriebsanleitung Seite 2

Charging the Battery Pack
The battery pack charges automatically when the
oscilloscope is connected to line power. For a
more efficient charge, use the optional external
charger (TDS3CHG).
When the battery pack is in the oscilloscope, the
gauge icon ( ) on the display indicates the
amount of charge.
S
To avoid automatic shutdown of the battery
pack, run the oscilloscope on the battery pack
only when the gauge indicates sufficient
charge.
S
To ensure the accuracy of the gauge, occasion-
ally allow the oscilloscope to run on the bat-
tery pack until automatic shutdown occurs.
NOTE. The TDS3CHG external charger may
increase the available charge and reset the
gauge to a higher level. Subsequent charges
using the oscilloscope may indicate less than
a full charge.

CAUTION.
pack, use only the oscilloscope or the
TDS3CHG battery charger to charge the
battery pack. Do not connect any other
voltage source to the battery pack.
NOTE. Charge the battery pack completely
before using it for the first time or after
prolonged storage. Several charge/discharge
cycles may be required before the battery
pack can charge to its full capacity.
NiCad batteries appear to lose capacity if not
allowed to occasionally discharge completely.
Every few months, run your oscilloscope until it
shuts down and then recharge the battery pack
completely to keep your battery pack at peak
performance.
To discharge the battery pack completely, continue
to run the oscilloscope on the battery pack until
automatic shutdown occurs. The display may turn
white a few minutes before the automatic
shutdown to allow the oscilloscope to completely
discharge the battery pack.
NOTE.
and to prevent shutdown, do not operate or
charge the battery pack at high
temperatures. For best results, allow the
battery pack to cool to room temperature
before using or charging the battery pack.
The battery pack stops charging under the
following conditions:
S
The battery pack is fully charged
S
The battery pack temperature exceeds +45_ C
S
The charge time exceeds 4.5 hours when
charging with the TDS3CHG
S
The charge time exceeds 24 hours when
charging in the TDS3000 series oscilloscope.
The battery pack shuts down and disconnects
itself from the TDS3000 series oscilloscope under
the following conditions:
S
The battery pack is fully discharged
S
There is a fault current in excess of 7A
S
The temperature inside the battery pack
compartment exceeds 70_ C
