Warning:
The channels should adopt common basis during measuring. To prevent short
circuits, the 2 probe ground must not be connected to 2 different non-isolated DC
level.

It is not allowed to measure AC power when the AC-powered oscilloscope is
connected to the AC-powered PC through the ports.
Warning:
To avoid fire or electrical shock, when the oscilloscope input signal
connected is more than 42 V peak (30 Vrms) or on circuits of more than
4800VA, please take note of below items:
 Only use accessory insulated voltage probes and test lead.
 Check the accessories such as probe before use and replace it if
there are any damages.
 Remove probes, test leads and other accessories immediately after
use.
 Remove USB cable which connects oscilloscope and computer.
 Do not apply input voltages above the rating of the instrument
because the probe tip voltage will directly transmit to the
oscilloscope. Use with caution when the probe is set as 1:1.
 Do not use exposed metal BNC or banana plug connectors.
 Do not insert metal objects into connectors.
