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.
