It is not allowed to measure AC power when the oscilloscope is AC powered through the adapter, or
when the oscilloscope powered by PC USB is connected to the AC-powered PC through the ports.
Warning:
To avoid fire or electrical shock if a test tool input is connected to more 42V
circuits of more than 4800VA:
Use only insulated probes and adapter supplied with the Oscilloscope.
Before use, inspect probes and accessories for mechanical damage and replace when damaged.
Remove all probes and accessories 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.
Do not touch the exposed part of metal BNC.
Do not insert metal objects into connectors.
Always use the Oscilloscope 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, which is applicable for appliances and portable
equipment.
