AC Power Source
The instrument operates from a single-phase, 100 to 240
V
(+/-10%) AC power source at 50/60 Hz (+/-5%), or
rms
single-phase 100 to 120 V
400 Hz (+/-5%).
No manual voltage selection is required because the
instrument automatically adapts to line voltage.
Depending on the accessories installed (front panel probes,
PC port plug-ins, etc.), the instrument can draw up to 340 W
(340 VA); WaveRunner model 62Xi: 290 W (290 VA).
Power and Ground Connections
The instrument is provided with a grounded cord set containing
a molded three-terminal polarized plug and a standard IEC320
(Type C13) connector for making line voltage and safety ground
connection. The AC inlet ground terminal is connected directly
to the frame of the instrument. For adequate protection against
electrical shock hazard, the power cord plug must be inserted
into a mating AC outlet containing a safety ground contact. Use
only the power cord specified for this instrument and certified for
the country of use.
The DSO should be positioned to allow easy access to the
socket-outlet. To completely remove power to the DSO, unplug
the instrument's power cord from the AC outlet after the DSO is
placed in Standby state.
In Standby state the DSO is still connected to the AC supply.
The instrument can only be placed in a complete Power Off
state by physically disconnecting the power cord from the AC
supply. It is recommended that the power cord be unplugged
from the AC outlet if the DSO is not being used for an extended
period of time.
See On/Standby Switch for more information.
On/Standby Switch
The front panel On/Standby switch controls the operational state of the DSO. This toggle switch is activated by
momentarily pressing and releasing it.
There are two basic DSO states: On or Standby. In the "On" state, the DSO, including its computer subsystems
(CPU, hard drive, etc,) is fully powered and operational. In the "Standby" state, the DSO, including computer
subsystems, is powered off with the exception of some "housekeeping" circuitry (approximately 12 watts
dissipation).

WARNING
Electric Shock Hazard!
Any interruption of the protective conductor
inside or outside of the DSO, or disconnection
of the safety ground terminal creates a
hazardous situation.
Intentional interruption is prohibited.
CAUTION
The outer shells of the front panel terminals
(CH1, CH2, CH3, CH4, EXT) are connected to
the instrument's chassis and therefore to the
safety ground.
