Once the battery is located in its compartment, follow the external power supply
start-up instructions.
•
To speed up recharging of the battery, switch off the power to the
oscilloscope by a long press on the ON/OFF button.
•
Battery fully discharged: during the first 10 minutes, the CHARGE LED of the
external power supply flashes, indicating that the battery is slow-charging.
The CHARGE LED then lights up when it switches to fast-charging.
During the charging of the battery (after 15 min), the startup of the
oscilloscope causes the premature stop of the load. It is possible to restart
the charging while disconnecting, then reconnecting the charger.
The LED goes out when the battery is fully charged (approx. 2h30).
When the oscilloscope is connected to 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 approx. 5 1/2 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.
When the oscilloscope is powered by a battery, an charge status indicator is
included in the display area of the current value:
The battery is 100% charged
The battery is 80% charged
The battery is 60% charged, etc.
If only one charge level 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 total
ly dead and the screen is about to be deactivated. You must
either recharge the battery or connect the instrument to the
external power supply.
If you change battery, a complete battery charge and discharge cycle (until the
instrument is automatically deactivated when discharging has finished) is
essential to calibrate this indicator.
To maintain the battery in good condition, use the oscilloscope at least until
the level before recharging.
