Quick Guide for DS1000B Series 
III 
 
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.
