Charging the oscilloscope
The are several charging options: Use the included USB charger, plugged into a computer USB
port, a mains to USB adaptor, a car 12V to USB adaptor or any USB type socket that can supply
5V/500mA. For measurements during charging, it is strongly advised to use a 9Vdc/min 200mA
mains adaptor.
Charging of completely drained batteries can take up to 7 hours. The charge LED indicator will
light while the scope is charging.
Quick use of the oscilloscope
After turning ON, a start-up screen appears. During this time, some
calibrations are performed, so it can take a few seconds before the
oscilloscope is ready for use.
The scope always starts in full auto set-up mode. This mode can be
used for most
(

)
signals. Set the input coupling to "DC" if
very low frequencies or DC voltages are measured (see further).
