Do Not Operate With Suspected Failures. If suspected damage
occurs with the instrument, have it inspected by qualified service
personnel before further operations.
Provide Proper Ventilation. Refer to the installation instructions
for proper ventilation of the instrument.
Do not Operate in Wet/Damp Conditions.
Do not Operate in an Explosive Atmosphere.
Keep Product Surfaces 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 DS1000B 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 300Vrms. To avoid the danger of electric shock, do
not connect the inputs to circuit’s voltages above 300Vrms.
Transient overvoltage is also present on circuits that are isolated
from mains. The DS1000B 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.
