Charging the Battery while using the Oscilloscope
When the oscilloscope is connected to the AC power via the external
power supply, it is possible to perform slow-charging of the battery. The
CHARGE LED of the external power supply lights up. Full recharging of a
totally discharged battery then takes approximately five and a half hours.
The LED goes out when the battery is fully charged.
Frequently recharging a battery when it is not fully discharged
reduces its life span.
1.4
Powering the Instrument with the Battery
When the oscilloscope is powered by a battery, a charge status indicator
appears in the display area:
the battery is 100% charged
the battery is 80% charged
the battery is 60% charged, etc.
If only one charge bar is present, it means that the battery can
only operate for a few minutes more, so you are advised to
recharge it or switch to the AC power supply.
The battery is totally dead and the screen is about to shut off.
You must either recharge the battery or connect the instru-
ment to the external power supply.
To maintain good condition of the battery, use the oscilloscope until at
least one bar remains before recharging.
1.5
