Safety Symbols
Electrical Shock hazard.
Refer to the operating user manual for warning information to
avoid hazard or personal injury and prevent damage to
instrument.
This symbol shows that the switch is a power switch located at
the front panel. Pressing this button turns on the oscilloscope,
and holding it down for a few seconds turns off the
oscilloscope.
CATI
CATII Category I overvoltage conditions.
Measurement instruments whose measurement inputs are
not intended to be connected to the mains supply. The
voltages in the environment are typically derived from a
limited-energy transformer or a battery.
Category II overvoltage conditions.
Measurement instruments whose measurement inputs are
meant to be connected to the mains supply at a standard wall
outlet or similar sources.
CATIII Category III overvoltage conditions.
Measurement instruments whose measurement inputs are
meant to be connected to the mains installation of a building.
