Please use the attached adapter to pre-charge the device for 0.5 to 1 hour (depen
ding on the storage time) before turning it on. In addition, if the device is not used
for a long time, it is recommended to charge it at regular intervals to avoid over-di
scharge of the lithium battery.
Battery Charging
The lithium battery may not be fully charged at the factory. To fully charge the
battery, it takes about 3 hours to charge (when the device is turned off) or subject
to the charging indicator. After charging, the battery can supply power for about 10
hours (varies depending on the working state).
When using battery power, a battery indicator will appear at the top of the screen
to show battery usage. The symbol indicates that there are only about five
minutes of usage remaining. To charge the battery and power the instrument,
connect the USB to DC cable to charge the battery. Turning off the instrument
increases charging speed.
Charging Method
Connect the oscilloscope to an adapter or other device for charging via a
USB-to-DC data cable or Type-C interface (pay attention to the load capacity of
the power supply device, and an adapter of 2A or greater should be used to
prevent the device from working abnormally).
Note
To avoid overheating of the battery during charging, the ambient temperature must
not exceed the allowable value given in the technical specifications.
Replacement of Lithium Battery
Generally, the battery does not need to be replaced. However, when necessary, it
can only be replaced by qualified personnel, and only lithium batteries of the
same specification can be used.
