Charging the Battery Pack
The battery pack charges automatically when the
oscilloscope is connected to the external power supply. You
can also charge the battery pack with the external power
supply and the optional THSCHG battery charger base.
You do not need to continuously charge (trickle charge)
Li-Ion battery packs to maintain full operating capacity
between jobs. However, a Lithium-Ion battery pack will
self-discharge during non-use. To achieve the longest
operating time, charge your battery pack before use. If you
plan to store battery packs, read the speci
fi
c instructions to
do this. Do not leave a battery on prolonged charge when
not in use.
When the battery pack is in the oscilloscope, the gauge
icon on the oscilloscope display indicates the amount of
charge in increments of approximately 25% each. You can
also access battery information through the Version and
Calibration tab in the oscilloscope User menu.
To avoid automatic shutdown of the battery pack, only
run the oscilloscope on the battery pack when the gauge
on the oscilloscope indicates 25% or more charge.
To ensure the accuracy of the gauge, occasionally
allow the oscilloscope to run on the battery pack until
automatic shutdown occurs.
Always verify the correct placement of the battery in
the product or the External Battery Charger.
CAUTION.
To avoid damage to the battery pack, use
only the oscilloscope or the THSCHG battery charger
to charge the battery pack. Do not connect any other
voltage source to the battery pack.
CAUTION.
To avoid overheating of the batteries
during charging, do not exceed the allowable ambient
temperature given in the speci
fi
cations.
NOTE.
For optimum performance, charge the battery
pack completely before using it for the
fi
rst time or after
prolonged storage.
To discharge the battery pack completely, continue to
run the oscilloscope on the battery pack until automatic
shutdown occurs.
NOTE.
To prolong the life of the battery pack 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.
Cold temperatures adversely affect the normal
electrochemical reactions within a battery pack, reducing
the available capacity. You can minimize this loss by
keeping the battery packs at room temperature prior to and
during use.
Do not leave a battery pack discharged for extended periods.
See the Storing Battery Packs section for information on
how to properly store a battery pack.
The battery pack switches to trickle charging when the
battery pack is fully charged.
Battery Use Guidelines
Do not leave a battery unused for an extended period of
time, either in the product or in storage. When a battery
has been unused for six months, check the charge status,
and charge or dispose of the battery as appropriate. See
Charging the Battery Pack
and
Battery Recycling
.
The typical estimated life of a Lithium-Ion battery is about
two to three years, or 300 to 500 charge cycles, whichever
occurs
fi
rst. One charge cycle is a period of use from fully
charged, to fully discharged, and fully recharged again. You
should use a two to three year life expectancy for batteries
that do not run through complete charge cycles.
A rechargeable Lithium-Ion battery has a limited life and
will gradually lose its capacity to hold a charge. This loss
of capacity (aging) is irreversible. As the battery loses
capacity, the length of time it will power the product (run
time) decreases.
A Lithium-Ion battery continues to slowly discharge
(self-discharge) when not in use or while in storage. You
need to routinely check the charge status of the battery.
Use the battery only in the application for which it is
intended. Use only THSBAT battery packs in your
THS3000 series oscilloscope.
Maintaining the Battery Pack
Observe and note the run time that a new fully-charged
battery provides for powering your product. You can
use this new battery run time as a basis to compare run
times for older batteries. The run time of your battery
will vary depending on the product’s con
fi
guration and
the applications that you run.
The battery pack gives the best performance when
operated at normal room temperature, 20 °C ±5 °C
(68 °F ±9 °F).
Routinely check the charge status of the battery.
Carefully monitor a battery that is approaching the end
of its estimated life.
Consider replacing the battery with a new one if
the battery run time drops below about 80% of the
original run time, or the battery charge time increases
signi
fi
cantly.
Follow the storage requirements if you store or do not
use a battery for an extended period. If you do not
follow the storage requirements, and the battery will
not power the oscilloscope when installed, consider the
battery to be damaged. Do not connect power to the
oscilloscope during this time. Remove the battery pack
from the oscilloscope. Do not attempt to recharge or
reuse the battery. Replace it with a new battery.
Handling Battery Packs
Do not disassemble, crush, or puncture the battery.
Do not short the external contacts on the battery.
Do not dispose of the battery in
fi
re or water.
Do not expose the battery to temperatures above
+60 °C (+140 °F).
Seek medical advice if a battery or part of it has been
swallowed.
Do not put battery packs near heat or
fi
re. Do not put
in sunlight.
Keep the battery pack clean and dry. Clean dirty
connectors with a dry, clean cloth.
Batteries contain hazardous chemicals that can cause
burns or explode. If exposure to chemicals occurs,
clean with water and get medical aid. Repair the
product before use if the battery leaks.
Do not attempt to open, modify, reform or repair a
battery pack that appears to be malfunctioning, or
which has been physically damaged.
Keep the battery away from children and animals.
Avoid exposing the battery to excessive shock or
vibration.
Do not use a damaged battery or charger.
If a battery pack has leaking
fl
uids, do not touch any
fl
uids. Dispose of a leaking battery pack. See the
Battery Recycling
section for information on Disposal
and Recycling.
In case of eye contact with
fl
uid, do not rub eyes.
Immediately
fl
ush eyes thoroughly with water for at
least 15 minutes, lifting upper and lower lids, until no
evidence of the
fl
uid remains. Seek medical attention.
