OWON HDS1021M Handheld DSO & DMM 2-Safety Information
2.2 General Safety Information
Carefully read the following safety information in order to avoid any personal injury and damage
on this product or any products connected with it. This product can only be used in the specified
applications to prevent any possible dangers.
Warning:
To avoid fire or electrical shock. Please use proper power adapter. Use only the power
adapter appointed by the manufacturer and subject to approval of being used in the user’s
country.
Warning:
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 than 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 (power adapter, USB line) that are not in
use.
● 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.
● Voltage ratings that are mentioned in the warning are giver as limits for “working
voltage”. The represent V ac rms (50-60Hz) for AC sine wave applications and as V dc
for DC applications. Overvoltage Category Ⅱ refers to local level, CAT is the prefix
refers to level II, Class II is a low-voltage high-energy level, which is applicable for
appliances and portable equipment.
