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
:
In X-Y mode, the X Input and Y Input 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.

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.
 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.
