Keep Well Ventilation.
Inadequately ventilated will cause the temperature rises or damages to the device.
Please keep well ventilation and inspect the intake and fan regularly.
Do not Operate in Wet/Damp Conditions.
In order to avoid short circuit to the interior of the device or electric shock, please do
not operate in a humid environment.
Do not Operate in an Explosive atmosphere.
In order to avoid damages to the device or personal injury, please operate far away
from an explosive atmosphere.
Keep Product Surfaces Clean and Dry.
In order to prevent the performance of the device from influencing by dust or water in
air, please keep the surface of device clean and dry.
The disturbance test of all the models meet the limit values of A in the
standard of EN 61326: 1997+A1+A2+A3, but can't meet the limit values of
B.
Measurement Category
The DS1000E, DS1000D series Digital Oscilloscope is intended to be used for
measurements in Measurement Category I.
Measurement Category Definitions
Measurement Category I is for measurements performed on circuits not directly
connected to MAINS. Examples are measurements on circuits not derived from MAINS,
and specially protected (internal) MAINS derived circuits. In the latter case, transient
stresses are variable; for that reason, the transient withstand capability of the
equipment is made known to the user.
WARNING
IEC Measurement Category I, The input terminals may be connected to circuit
terminal in IEC Category I installations for voltages up to 300 VAC. To avoid the
danger of electric shock, do not connect the inputs to circuit's voltages above 300 VAC.
Transient overvoltage is also present on circuits that are isolated from mains. The
DS1000E, DS1000D series Digital Oscilloscopes is designed to safely withstand
occasional transient overvoltage up to 1000Vpk. Do not use this equipment to
measure circuits where transient overvoltage could exceed this level.
