To avoid body damage and prevent product and connected equipment damage, carefully
read the following safety information before using the test tool. This product can only be
used in the specified applications.
Warning:
The two channels of the oscilloscope are not electrically isolated. The channels should
adopt a common ground during measuring. To prevent short circuits, the 2 probe
grounds must not be connected to 2 different non-isolated DC levels.

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
42V peak (30Vrms) 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.
