1. General Safety Requirements
Before use, please read the following safety precautions to avoid any possible bodily
injury and to prevent this product or any other connected products from damage. In
orderto avoid any contingent danger, ensure this product is only used within the range
specified.
Only the qualified technicians can implement the maintenance.
To avoid Fire or Personal Injury:
Connect the probe correctly. The grounding end of the probe corresponds to the
grounding phase. Please don't connect the grounding end to the positive phase.
Use Proper Power Cord. Use only the power cord supplied with the product and
certified to use in your country.
Connect or Disconnect Correctly. When the probe or test lead is connected to a
voltage source, please do not connect and disconnect the probe or test lead at random.
Product Grounded. This instrument is grounded through the power cord grounding
conductor. To avoid electric shock, the grounding conductor must be grounded. The
product must be grounded properly before any connection with its input or output
terminal.
When powered byAC power, itis not allowed tomeasureAC powersource directly,
because the testing ground and power cord ground conductor are connected
together, otherwise, it will cause short circuit.
When powered by battery, the product must ground connection. To avoid electric
shock, there must be a ground wire connect between ground and the ground port
(on the back of product panel).
Check all Terminal Ratings. To avoid fire or shock hazard, check all ratings and
markers of this product. Refer to the user's manual for more information about ratings
before connecting to the instrument.
Do not operate without covers. Do not operate the instrument with covers or panels
removed.
Use Proper Fuse. Use only the specified type and rating fuse for this instrument.
Avoid exposed circuit. Do not touch exposed junctions and components when the
instrument is powered.
Do not operate if in any doubt. If you suspect damage occurs to the instrument, have
it inspected by qualified service personnel before further operations.
Use your Oscilloscope in a well-ventilated area. Make sure the instrument installed
with proper ventilation, refer to the user manual for more details.
Do not operate in wet conditions.
Do not operate in an explosive atmosphere.
Keep product surfaces clean and dry.

Safety Terms
Terms in this manual. The following terms may appear in this manual:
Warning: Warning indicates the conditions or practices that could result in injury
or loss of life.
Caution: Caution indicates the conditions or practices that could result in damage
to this product or other property.
Terms on the product. The following terms may appear on this product:
Danger: It indicates an injury or hazard may immediately happen.
Warning: It indicates an injury or hazard may be accessible potentially.
Caution: It indicates a potential damage to the instrument or other property might occur.
Safety Symbols
Symbols on the product. The following symbol may appear on the product:
Hazardous Voltage Refer to Manual
Protective Earth Terminal Chassis Ground
Test Ground
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 four 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.

The diagram of the oscilloscope ground wire connection:
The diagram of the ground wire connection when the battery-powered oscilloscope is
connected to the AC-powered PC through the ports:
It is not allowed to measureAC power when the oscilloscope is AC powered, or when
the battery-powered oscilloscope is connected to theAC-powered PC through theports.
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.
