Charging the Batteries

batteries. The battery symbols are:
. The
symbol indicates that there are typically five minutes
of operating time left. See also Displaying Battery
Information on page 101.
To charge the batteries and power the instrument, connect
the power adapter as shown in Figure 46. To charge the
batteries more quickly, turn off the test tool.
Caution
To avoid overheating of the batteries during
charging, do not exceed the allowable
ambient temperature given in the
specifications.
Note
No damage will occur if the power adapter is
connected for long periods, e.g., during the
weekend. The instrument then automatically
switches to trickle charging.
