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 
DS1000B  series  Digital  Oscilloscopes  is  designed  to  safely  withstand  occasional 
transient overvoltage up to 1000 Vpk. Do not use this equipment to measure circuits 
where transient overvoltage could exceed this level.
