It is not allowed to measure AC power when charging the oscilloscope with adapter.
Warning:
To avoid fire or electrical shock if a test tool input is connected to more 42V peak (30Vrms)
or on circuits of more than 4800VA:
● Use only insulated voltage probes, test leads and adapter supplied with the test tool, or
indicated by OWON as suitable for the Oscilloscope & Multimeter.
● Before use, inspect voltage probes, test leads and accessories for mechanical damage and
replace when damaged.
● Remove all probes, test leads and accessories that are not in use.
● Always connect the power adapter first to the AC outlet before connecting it to the
Oscilloscope & Multimeter.
● Do not apply voltages that differ more than 400 V from earth ground to any input when
measuring in a CAT Ⅱ environment.
● Do not apply voltages that differ more than 400 V from each other to the isolated inputs
when measuring in a CAT Ⅱ environment.
● Do not apply input voltages above the rating of the instrument Use caution when using
1:1 test leads because the probe tip voltage will be directly transmitted to the
Oscilloscope & Multimeter.
● Do not use exposed metal BNC or banana plug connectors.
● Do not insert metal objects into connectors.
● Always use the Oscilloscope & Multimeter only in the manner specified.

4.1 Performing the General Inspection
When you have got a new HDS1021M series oscilloscope, it is suggested that you should perform
a general inspection on the instrument according to the following steps.
4.1.1 Check whether there is any Damage on it Due to Transportation
If the packing boxes or foam cushions are found in serous damage, keep them in a proper place till
the complete instrument and accessories have passed the electrical and mechanical tests.
4.1.2 Make a Check on Accessories
The accessory list has been described in the picture of Digital Oscilloscope Parts of this manual.
You can make a check and find whether there is any accessory loss with reference to the
Appendix. In case of any accessory loss or damage, consult the OWON dealer responsible for
such a business or the local office of OWON.
4.1.3 Make a Check on the Complete Instrument
If the instrument is damaged in its appearance or it fails in normal operation or performance test,
consult the OWON dealer responsible for such a business or the local office of OWON. If the
instrument is damaged due to transportation, keep the packing in a proper place and consult the
transportation department and the OWON dealer responsible for such business, who will provide
an instrument replacement or maintenance.
